The TVP5146 decoder supports the analog-to-digital (A/D) conversion of component RGB and YPbPr signals, as well as the A/D conversion and decoding of NTSC, PAL, and SECAM composite and S-video into component YCbCr. This decoder includes four 10-bit 30-MSPS A/D converters (ADCs). Preceding each ADC in the device, the corresponding analog channel contains an analog circuit that clamps the input to a reference voltage and applies a programmable gain and offset. A total of 10 video input terminals can be configured to a combination of RGB, YPbPr, CVBS, or S-video video inputs. Component, composite, or S-video signals are sampled at 2× the square-pixel or ITU-R BT.601 clock frequency, line-locked, and are then decimated to the 1× pixel rate. CVBS decoding utilizes five-line adaptive comb filtering for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap filter is also available. On CVBS and S-video inputs, the user can control video characteristics such as contrast, brightness, saturation, and hue via an I2C host port interface. Furthermore, luma peaking (sharpness) with programmable gain is included, as well as a patented chroma transient improvement (CTI) circuit. A built-in color space converter is applied to decoded component RGB data. The following output formats can be selected: 20-bit 4:2:2 YCbCr or 10-bit 4:2:2 YCbCr. The TVP5146 decoder generates synchronization, blanking, field, active video window, horizontal and vertical syncs, clock, genlock (for downstream video encoder synchronization), host CPU interrupt and programmable logic I/O signals, in addition to digital video outputs. The TVP5146 decoder includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI data processor (VDP) slices, parses, and performs error checking on teletext, closed caption (CC), and other VBI data. A built-in FIFO stores up to 11 lines of teletext data, and with proper host port synchronization, full-screen teletext retrieval is possible. The TVP5146 decoder can pass through the output formatter 2× the sampled raw luma data for host-based VBI processing. The decoder provides the option for concurrent processing of pixel-locked CVBS and RGB/YPbPr input formats. The main blocks of the TVP5146 decoder include: • Robust sync detection for weak and noisy signals as well as VCR trick modes • Y/C separation by 2-D, 5-line, adaptive comb or chroma trap filter • Fast-switch input for pixel-by-pixel switching between CVBS and YPbPr/RGB component video inputs (SCART support) • Four 10-bit, 30-MSPS A/D converters with analog preprocessors [clamp and automatic gain control (AGC)] • Luminance processor • Chrominance processor Macrovision is a trademark of Macrovision Corporation.

Analog Processors and A/D Converters 2.1.1 Video Input Switch Control The TVP5146 decoder has 4 analog channels that accept up to 10 video inputs. The user can configure the internal analog video switches via the I2C interface. The 10 analog video inputs can be used for different input configurations, some of which are: • Up to 10 selectable individual composite video inputs • Up to four selectable S-video inputs • Up to three selectable analog YPbPr/RGB video inputs and one CVBS input • Up to two selectable analog YPbPr/RGB video inputs, two S-video inputs, and two CVBS inputs The input selection is performed by the input select register at I2C subaddress 00h (see Section 2.11.1). SLES084C − August 2007 TVP5146 9 2.1.2 Analog Input Clamping An internal clamping circuit restores the ac-coupled video signal to a fixed dc level. The clamping circuit provides line-by-line restoration of the video sync level to a fixed dc reference voltage. The selection between bottom and mid clamp is performed automatically by the TVP5146 decoder. 2.1.3 Automatic Gain Control The TVP5146 decoder uses four programmable gain amplifiers (PGAs), one per channel. The PGA can scale a signal with a voltage-input compliance of 0.5-VPP to 2-VPP to a full-scale 10-bit A/D output code range. A 4-bit code sets the coarse gain with individual adjustment per channel. Minimum gain corresponds to a code 0x0 (2-VPP full-scale input, –6-dB gain) while maximum gain corresponds to code 0xF (0.5 VPP full scale, +6-dB gain). The TVP5146 decoder also has 12-bit fine gain controls for each channel and applies independently to coarse gain controls. For composite video, the input video signal amplitude can vary significantly from the nominal level of 1 VPP. The TVP5146 decoder can adjust its PGA setting automatically: an AGC can be enabled and can adjust the signal amplitude such that the maximum range of the ADC is reached without clipping. Some nonstandard video signals contain peak white levels that saturate the ADC. In these cases, the AGC automatically cuts back gain to avoid clipping. If the AGC is on, then the TVP5146 decoder can read the gain currently being used. The TVP5146 AGC comprises the front-end AGC before Y/C separation and the back-end AGC after Y/C separation. The back-end AGC restores the optimum system gain whenever an amplitude reference such as the composite peak (which is only relevant before Y/C separation) forces the front-end AGC to set the gain too low. The front-end and back-end AGC algorithms can use up to four amplitude references: sync height, color burst amplitude, composite peak, and luma peak. The specific amplitude references being used by the front-end and back-end AGC algorithms can be independently controlled using the AGC white peak processing register located at subaddress 74h. The TVP5146 gain increment speed and gain increment delay can be controlled using the AGC increment speed register located at subaddress 78h and the AGC increment delay register located at subaddress 79h, respectively. 2.1.4 Analog-to-Digital Converters (ADCs) All ADCs have a resolution of 10 bits and can operate up to 30 MSPS. All A/D channels receive an identical clock from the on-chip phase-locked loop (PLL) at a frequency between 24 MHz and 30 MHz. All ADC reference voltages are generated internally. 2.2 Digital Video Processing Figure 2−2 is a block diagram of the TVP5146 digital video decoder processor. This processor receives digitized video signals from the ADCs and performs composite processing for CVBS and S-video inputs, YCbCr signal enhancements for CVBS and S-video inputs, and YPbPr/RGB processing for component video inputs. It also generates horizontal and vertical syncs and other output control signals such as genlock for CVBS and S-video inputs. Additionally, it can provide field identification, horizontal and vertical lock, vertical blanking, and active video window indication signals. The digital data output can be programmed to two formats: 20-bit 4:2:2 with external syncs or 10-bit 4:2:2 with embedded/separate syncs. The circuit detects pseudosync pulses, AGC pulses, and color striping in Macrovision-encoded copy-protected material. Information present in the VBI interval can be retrieved and either inserted in the ITU-R BT.656 output as ancillary data or stored in internal FIFO and/or registers for retrieval via the host port interface. 10 TVP5146 SLES084C − August 2007 Copy Protection Detector VBI Data Processor Slice VBI Data Y[9:0] Output Formatter CH1 A/D 2

Digital Video Processor Block Diagram 2.2.1 2y Decimation Filter All input signals are oversampled by a factor of 2 (27 MHz). The A/D outputs first pass through decimation filters that reduce the data rate to 1× the pixel rate. The decimation filter is a half-band filter. Oversampling and decimation filtering can effectively increase the overall signal-to-noise ratio by 3 dB. 2.2.2 Composite Processor Figure 2−3 is a block diagram of the TVP5146 digital composite video processing circuit. This circuit receives a digitized composite or S-video signal from the ADCs and performs Y/C separation (bypassed for S-video input), chroma demodulation for PAL/NTSC and SECAM, and YUV signal enhancements. The 10-bit composite video is multiplied by the subcarrier signals in the quadrature demodulator to generate color difference signals U and V. The U and V signals are then sent to low-pass filters to achieve the desired bandwidth. An adaptive 5-line comb filter separates UV from Y based on the unique property of color phase shifts from line to line. The chroma is remodulated through a quadrature modulator and subtracted from line-delayed composite video to generate luma. This form of Y/C separation is completely complementary, thus there is no loss of information. However, in some applications, it is desirable to limit the U/V bandwidth to avoid crosstalk. In that case, notch filters can be turned on. To accommodate some viewing preferences, a peaking filter is also available in the luma path. Contrast, brightness, sharpness, hue, and saturation controls are programmable through the host port.

However, for video sources that have asymmetrical U and V side bands, it is desirable to limit the filter bandwidth to avoid UV crosstalk. The color low-pass filter bandwidth is programmable to enable one of the three notch filters.

The comb filter can be selectively bypassed in the luma or chroma path. If the comb filter is bypassed in the luma path, then chroma trap filters are used which are shown in Figure 2−8 through Figure 2−11. TI’s patented adaptive comb filter algorithm reduces artifacts such as hanging dots at color boundaries. It detects and properly handles false colors in high frequency luminance images, such as a multiburst pattern or circle pattern. Adaptive comb filtering is the recommended mode of operation. 10 10 5 Notch 2 Filter 0 0 −5 −5 Amplitude − dB Amplitude − dB 5 −10 −15 −20 Notch 3 Filter Notch 1 Filter −25 Notch 3 Filter −10 Notch 1 Filter −15 −20 Notch 2 Filter −25 No Notch Filter −30 −30 No Notch Filter −35 −35 −40 −40 0 1 2 3 4 5 6 0 7 1 2 f – Frequency – MHz Figure 2−8.

The luminance signal is then fed into the input of a peaking circuit. Figure 2−12 illustrates the basic functions of the luminance data path. In the case of S-video, the luminance signal bypasses the comb filter or chroma trap filter and is fed directly to the circuit. High-frequency components of the luminance signal are enhanced by a peaking filter (sharpness). Figure 2−13, Figure 2−14, and Figure 2−15 show the characteristics of the peaking filter at four different gain settings that are programmable via the host port.

Peaking Filter Response, PAL Square Pixel Sampling 2.2.3.1 Color Transient Improvement Color transient improvement (CTI) enhances horizontal color transients by delay modulation for both color difference signals. The operation must be performed only on YCbCr-formatted data. The color difference signal transition points are maintained, but the edges are enhanced for signals which have bandwidth-limited color components (for example, CVBS and S-video). 2.2.4 Component Video Processor The component video processing block supports a user-selectable contrast, brightness, and saturation adjustment in YCbCr output formats. For YCbCr output formats, gain and offset values are applied to the luma data path in order to map the pixel values to the correct output range (for 10-bit Ymin = 64 and Ymax = 940), and to provide a means of adjusting contrast and brightness. For Y, digital contrast (gain) and brightness (offset) factors can vary from 0 to 255. The contrast control adjusts the amplitude range of the Y output centered at the midpoint of the output code range. The limit block limits the output to the ITU-R BT.601 range (Ymin to Ymax) or an extended range, depending on a user setting. Offset Y x + Limit Y Gain Figure 2−16. Y Component Gain, Offset, Limit 16 TVP5146 SLES084C − August 2007 For CbCr components, a saturation (gain) factor is applied to the CbCr inputs in order to map them to the CbCr output code range and provide saturation control. Similarly, the limit block can limit CbCr outputs to a valid range: Cb,Crmin = 64 / Cb,Crmax = 960 CbCr x Limit CbCr Gain Figure 2−17. CbCr Component Gain, Offset, Limit 2.2.5 Color Space Conversion The formulas for RGB to YCbCr conversion are given as: Y = 0.299 × R + 0.587 × G + 0.114 × B Cb = –0.172 × R – 0.339 × G + 0.511 × B + 512 Cr = 0.511 × R – 0.428 × G – 0.083 × B + 512 2.3 Clock Circuits An internal line-locked PLL generates the system and pixel clocks. A 14.31818-MHz clock is required to drive the PLL. This can be input to the TVP5146 decoder at the 1.8-V level on terminal 74 (XTAL1), or a crystal of 14.31818-MHz fundamental resonant frequency can be connected across terminals 74 and 75 (XTAL2). If a parallel resonant circuit is used as shown in Figure 2−18, then the external capacitors must have the following relationship: CL1 = CL2 = 2CL – CSTRAY, where CSTRAY is the terminal capacitance with respect to ground. Figure 2−18 shows the reference clock configurations. The TVP5146 decoder generates the DATACLK signal used for clocking data.

Reference Clock Configurations 2.4 Real-Time Control (RTC) Although the TVP5146 decoder is a line-locked system, the color burst information is used to determine accurately the color subcarrier frequency and phase. This ensures proper operation with nonstandard video signals that do not follow exactly the required frequency multiple between color subcarrier frequency and video line frequency. The frequency control word of the internal color subcarrier PLL and the subcarrier reset bit are transmitted via terminal 37 (GLCO) for optional use in an end system (for example, by a video encoder). The frequency control word is a 23-bit binary number. SLES084C − August 2007 TVP5146 17 The instantaneous frequency of the color subcarrier can be calculated from the following equation: F PLL + F ctrl 2 23 F sclk where FPLL is the frequency of the subcarrier PLL, Fctrl is the 23-bit PLL frequency control word, and Fsclk is two times the pixel frequency.

In the event that composite video and RGB video are present simultaneously on the video terminals assigned to a SCART interface, the TVP5146 decoder assumes they are pixel synchronous to each other. The timing for both composite video and RGB video is obtained from the composite source, and its derived clock is used to sample RGB video as well. The fast-switch input terminal allows switching between these two input video sources on a pixel-by-pixel basis. The fast switch is a hard switch; there is no alpha blending between both sources. 2.5.2 Separate Syncs VS, HS, and VBLK are independently software programmable to a 1× pixel count. This allows any possible alignment to the internal pixel count and line count. The default settings for 525-line and 625-line video outputs are given as examples below. FID changes at the same transient time when the trailing edge of vertical sync occurs. The polarity of FID is programmable by an I2C interface.

The I2C standard consists of two signals, the serial input/output data (SDA) line and the serial input clock line (SCL), which carry information between the devices connected to the bus. A third signal (I2CA) is used for slave address selection. Although an I2C system can be multimastered, the TVP5146 decoder functions as a slave device only. 24 TVP5146 SLES084C − August 2007 Because SDA and SCL are kept open-drain at a logic-high output level or when the bus is not driven, the user must connect SDA and SCL to a positive supply voltage via a pullup resistor on the board. The slave-address select signal, terminal 37 (I2CA), enables the use of two TVP5146 decoders tied to the same I2C bus by controlling the least significant bit of the I2C device address. Table 2−4. I2C Host Interface Terminal Description SIGNAL TYPE DESCRIPTION I2CA I Slave address selection SCL I Input clock line SDA I/O Input/output data line 2.6.1 Reset and I 2C Bus Address Selection The TVP5146 decoder can respond to two possible chip addresses. The address selection is made at reset by an externally supplied level on the I2CA terminal. The TVP5146 decoder samples the level of terminal 37 at power up or at the trailing edge of RESETB and configures the I2C bus address bit A0. The I2CA terminal has an internal pulldown resistor to pull the terminal low to set a zero. Table 2−5.

In accordance with I2C specifications, the TVP5146 decoder holds the I2C clock line (SCL) low to indicate the wait period to the I2C master. If the I2C master is not designed to check for the I2C clock line held-low condition, then the maximum delays must always be inserted where required. These delays are of variable length; maximum delays are indicated in the following diagram: Normal register S 2.7 1011 1000 ACK Subaddress ACK Send data ACK Wait 64 µs P VBI Data Processor The TVP5146 VBI data processor (VDP) slices various data services like teletext (WST, NABTS), closed caption (CC), wide screen signaling (WSS), program delivery control (PDC), vertical interval time code (VITC), video program system (VPS), copy generation management system (CGMS) data, and electronic program guide (Gemstar) 1x/2x. Table 2−6 shows the supported VBI system. These services are acquired by programming the VDP to enable the reception of one or more VBI data standard(s) in the VBI. The VDP can be programmed on a line-per-line basis to enable simultaneous reception of different VBI formats, one per line. The results are stored in a FIFO and/or registers. Because of its high data bandwidth, the teletext results are stored in FIFO only. The TVP5146 decoder provides fully decoded V-CHIP data to the dedicated registers at subaddresses 800540h–800543h (see Sections 2.12.4 through 2.12.7). Table 2−6.

VBI data is output on the Y[9:2] terminals during the horizontal blanking period. Table 2−7 shows the header format and sequence of the ancillary data inserted into the video stream. This format is also used to store any VBI data into the FIFO. The size of the FIFO is 512 bytes. Therefore, the FIFO can store up to 11 lines of teletext data with the NTSC NABTS standard. Table 2−7.

This is transmitted as an ancillary data block, although somewhat differently from the way the sliced VBI data is transmitted in the FIFO format as described in Section 2.7.1. The samples are transmitted during the active portion of the line. VBI raw data uses ITU-R BT.656 format having only luma data. The chroma samples are replaced by luma samples. The TVP5146 decoder inserts a four-byte preamble 000h 3FFh 3FFh 180h before data start. There are no checksum bytes and fill bytes in this mode. Table 2−8. VBI Raw Data Output Format BYTE NO.

If using the 20-/16-bit mode or using this terminal as GPIO, then this terminal must be pulled low through a 2.2-kΩ pulldown resistor (see Figure 5−1). If unused, this terminal can be shorted to ground. (Note: If using the 20-/16-bit mode and only using the 16 MSBs, it is possible to short terminal 69 to GND, but the current for IOVDD will increase by 2 or 3 mA.) After reset, the user must write the following I2C commands to the TVP5146: STEP I2C SUBADDRESS I2C DATA 1 0xE8 0x02 2 0xE9 0x00 3 0xEA 0x80 4 0xE0 0x01 5 0xE8 0x60 6 0xE9 0x00 7 0xEA 0xB0 8 0xE0 0x01 9 0xE0 0x00 10 0x03 0x01 11 0x03 0x00 Afterward, the user programs the device as usual. 2.9 Adjusting External Syncs The proper sequence to program the following external syncs is: • • • To set NTSC, PAL-M, NTSC 443, PAL60 (525-line modes): − Set the video standard to NTSC (register 02h) − Set HSYNC, VSYNC, VBLK, and AVID external syncs (registers 16h through 24h) To set PAL, PAL-N, SECAM (625-line modes): − Set the video standard to PAL (register 02h) − Set HSYNC, VSYNC, VBLK, and AVID external syncs (registers 16h through 24h) For autoswitch, set the video standard to autoswitch (register 02h) 2.10 Internal Control Registers The TVP5146 decoder is initialized and controlled by a set of internal registers that define the operating parameters of the entire decoder. Communication between the external controller and the TVP5146 decoder is through a standard I2C host port interface, as described earlier. Table 2−10 shows the summary of these registers. Detailed programming information for each register is described in the following sections. Additional registers are accessible through an indirect procedure involving access to an internal 24-bit address wide VBUS. Table 2−11 shows the summary of the VBUS registers. NOTE: Do not write to reserved registers. Reserved bits in any defined register must be written with 0s, unless otherwise noted. 30 TVP5146 SLES084C − August 2007 Table 2−10.

Application Example SLES084C − August 2007 TVP5146 93 5.2 Designing With PowerPADt Devices The TVP5146 device is housed in a high-performance, thermally enhanced, 80-terminal PowerPAD package (TI package designator: 80PFP). Use of the PowerPAD package does not require any special considerations except to note that the thermal pad, which is an exposed die pad on the bottom of the device, is a metallic thermal and electrical conductor. Therefore, if not implementing the PowerPAD PCB features, the use of solder masks (or other assembly techniques) may be required to prevent any inadvertent shorting by the exposed thermal pad of connection etches or vias under the package. The recommended option, however, is not to run any etches or signal vias under the device, but to have only a grounded thermal land as explained in the following paragraphs. Although the actual size of the exposed die pad may vary, the minimum size required for the keep-out area for the 80-terminal PFP PowerPAD package is 8 mm × 8 mm. It is recommended that there be a thermal land, which is an area of solder-tinned copper, underneath the PowerPAD package. The thermal land varies in size, depending on the PowerPAD package being used, the PCB construction, and the amount of heat that needs to be removed. In addition, the thermal land may or may not contain numerous thermal vias depending on PCB construction. Other requirements for using thermal lands and thermal vias are detailed in the PowerPADt Thermally Enhanced Package technical brief, TI literature number SLMA002, available via the TI Web pages at URL http://www.ti.com. For the TVP5146 device, this thermal land must be grounded to the low-impedance ground plane of the device. This improves not only thermal performance but also the electrical grounding of the device. It is also recommended that the device ground terminal landing pads be connected directly to the grounded thermal land. The land size must be as large as possible without shorting device signal terminals. The thermal land may be soldered to the exposed thermal pad using standard reflow soldering techniques. While the thermal land may be electrically floated and configured to remove heat to an external heat sink, it is recommended that the thermal land be connected to the low impedance ground plane for the device. More information can be obtained from the TI Recommendations for PHY Layout applicaton report, TI literature number SLLA020.
