ADV7344 has a 30-bit pixel input port that can be configured in a variety of ways. SD video formats are supported over a SDR interface and ED/HD video formats are supported over SDR and DDR interfaces. Pixel data can be supplied in either the YCrCb or RGB color spaces. The ADV7344 also supports embedded EAV/SAV timing codes, external video synchronization signals, and I2C and SPI communication protocols. In addition, simultaneous SD and ED/HD input and output is supported. 216 MHz (SD and ED) and 297 MHz (HD) oversampling ensures that external output filtering is not required, while full-drive DACs ensure that external output buffering is not required. Cable detection and DAC auto power-down features keep power consumption to a minimum. Table 1 lists the video standards directly supported by the ADV7344. Table 1.

In DNR mode, the range of gain values is 0 to 1 in increments of 1/8. This factor is applied to the DNR filter output that lies below the set threshold range. The result is then subtracted from the original signal. In DNR sharpness mode, the range of gain values is 0 to 0.5 in increments of 1/16. This factor is applied to the DNR filter output that lies above the threshold range. The result is added to the original signal. Block Size Control—Subaddress 0xA4, Bit 7 This bit is used to select the size of the data blocks to be processed. Setting the block size control function to Logic 1 defines a 16 pixel × 16 pixel data block, and Logic 0 defines an 8 pixel × 8 pixel data block, where one pixel refers to two clock cycles at 27 MHz. DNR Input Select Control—Subaddress 0xA5, Bits[2:0] Three bits are assigned to select the filter, which is applied to the incoming Y data. The signal that lies in the pass band of the selected filter is the signal that is DNR processed. Figure 80 shows the filter responses selectable with this control. 1.0 FILTER D 0.8 MAGNITUDE Coring Gain Data—Subaddress 0xA3, Bits[7:4] These four bits are assigned to the gain factor applied to the luma data inside the MPEG pixel block. In DNR mode, the range of gain values is 0 to 1 in increments of 1/8. This factor is applied to the DNR filter output that lies below the set threshold range. The result is then subtracted from the original signal. In DNR sharpness mode, the range of gain values is 0 to 0.5 in increments of 1/16.

Logic 0 selects DNR mode; Logic 1 selects DNR sharpness mode. DNR works on the principle of defining low amplitude, high frequency signals as probable noise and subtracting this noise from the original signal. In DNR mode, it is possible to subtract a fraction of the signal that lies below the set threshold, assumed to be noise, from the original signal. The threshold is set in DNR Register 1. When DNR sharpness mode is enabled, it is possible to add a fraction of the signal that lies above the set threshold to the original signal, because this data is assumed to be valid data and not noise. The overall effect is that the signal is boosted (similar to using the extended SSAF filter). Figure 78. SD DNR Offset Control DNR Threshold—Subaddress 0xA4, Bits[5:0] These six bits are used to define the threshold value in the range of 0 to 63. The range is an absolute value. Border Area—Subaddress 0xA4, Bit 6 When this bit is set to Logic 1, the block transition area can be defined to consist of four pixels. If this bit is set to Logic 0, the border transition area consists of two pixels, where one pixel refers to two clock cycles at 27 MHz. 720 × 485 PIXELS (NTSC) 2-PIXEL BORDER DATA DNR Block Offset Control—Subaddress 0xA5, Bits[7:4] Four bits are assigned to this control, which allows a shift of the data block of 15 pixels maximum. Consider the coring gain positions fixed. The block offset shifts the data in steps of one pixel such that the border coring gain factors can be applied at the same position regardless of variations in input timing of the data. 8 × 8 PIXEL BLOCK 8 × 8 PIXEL BLOCK Figure 79.

To utilize this low power mode, these DACs must be operating in full-drive mode (RSET = 510 Ω, RL = 37.5 Ω). Low power mode is not available in low drive mode (RSET = 4.12 kΩ, RL = 300 Ω). Low power mode can be independently enabled or disabled on DAC 1, DAC 2, and DAC 3 using Subaddress 0x0D, Bits[2:0]. Low power mode is disabled by default on each DAC. In low power mode, DAC current consumption is content dependent. On a typical video stream, it can be reduced by as much as 40%. For applications requiring the highest possible video performance, low power mode should be disabled. With this feature enabled, the cable detection circuitry monitors DAC 1 and/or DAC 2 once per frame. If they are unconnected, some or all of the DACs automatically power down. Which DAC or DACs are powered down depends on the selected output configuration. For CVBS/YC output configurations, if DAC 1 is unconnected, only DAC 1 powers down. If DAC 2 is unconnected, DAC 2 and DAC 3 power down. For YPrPb and RGB output configurations, if DAC 1 is unconnected, all three DACs power down. DAC 2 is not monitored for YPrPb and RGB output configurations. Once per frame, DAC 1 and/or DAC 2 are monitored. If a cable is detected, the appropriate DAC or DACs remain powered up for the duration of the frame. If no cable is detected, the appropriate DAC or DACs power down until the next frame when the process is repeated. CABLE DETECTION Subaddress 0x10 The ADV7344 includes an Analog Devices Inc. proprietary cable detection feature. The cable detection feature is available on DAC 1 and DAC 2, while operating in full-drive mode (RSET1 = 510 Ω, RL1 = 37.5 Ω, assuming a connected cable). The feature is not available in low drive mode (RSET = 4.12 kΩ, RL = 300 Ω). For a DAC to be monitored, the DAC must be powered up in Subaddress 0x00. The cable detection feature can be used with all SD, ED, and HD video standards. It is available for all output configurations, that is, CVBS, YC, YPrPb, and RGB output configurations. For CVBS/YC output configurations, both DAC 1 and DAC 2 are monitored, that is, the CVBS and YC luma outputs are monitored. For YPrPb and RGB output configurations, only DAC 1 is monitored, that is, the luma or green output is monitored. Once per frame, the ADV7344 monitors DAC 1 and/or DAC 2, updating Subaddress 0x10, Bit 0 and Bit 1, respectively. If a cable is detected on one of the DACs, the relevant bit is set to 0. If not, the bit is set to 1. PIXEL AND CONTROL PORT READBACK Subaddress 0x12 to Subaddress 0x16 The ADV7344 supports the readback of most digital inputs via the I2C/SPI MPU port. This feature is useful for board-level connectivity testing with upstream devices. The pixel port (S[9:0], Y[9:0], and C[9:0]), the control port (S_HSYNC, S_VSYNC, P_HSYNC, P_VSYNC and P_BLANK), and the SFL/MISO pin are available for readback via the MPU port. The readback registers are located at Subaddress 0x12 to Subaddress 0x16. When using this feature, a clock signal should be applied to the CLKIN_A pin in order to register the levels applied to the input pins. RESET MECHANISM Subaddress 0x17, Bit 1 The ADV7344 has a software reset accessible via the I2C/SPI MPU port. A software reset is activated by writing a 1 to Subaddress 0x17, Bit 1. This resets all registers to their default values. This bit is self-clearing, that is, after a 1 has been written to the bit, the bit automatically returns to 0. When operating in SPI mode, a software reset does not cause the device to revert to I2C mode. For this to occur, the ADV7344 needs to be powered down. The ADV7344 includes a power-on reset (POR) circuit to ensure correct operation after power-up. DAC AUTO POWER-DOWN Subaddress 0x10, Bit 4 For power sensitive applications, a DAC auto power-down feature can be enabled using Subaddress 0x10, Bit 4. This feature is only available when the cable detection feature is enabled. Rev. 0 | Page 64 of 88 ADV7344 PRINTED CIRCUIT BOARD LAYOUT AND DESIGN DAC CONFIGURATIONS The ADV7344 contains six DACs. All six DACs can be configured to operate in low drive mode. Low drive mode is defined as 4.33 mA full-scale current into a 300 Ω load, RL. DAC 1, DAC 2, and DAC 3 can also be configured to operate in full-drive mode. Full-drive mode is defined as 34.7 mA fullscale current into a 37.5 Ω load, RL. Full-drive is the recommended mode of operation for DAC 1, DAC 2, and DAC 3. The ADV7344 contains two RSET pins. A resistor connected between the RSET1 pin and AGND is used to control the fullscale output current and, therefore, the DAC output voltage levels of DAC 1, DAC 2, and DAC 3. For low drive operation, RSET1 must have a value of 4.12 kΩ, and RL must have a value of 300 Ω. For full-drive operation, RSET1 must have a value of 510 Ω, and RL must have a value of 37.5 Ω. A resistor connected between the RSET2 pin and AGND is used to control the full-scale output current and, therefore, the DAC output voltage levels of DAC 4, DAC 5, and DAC 6. RSET2 must have a value of 4.12 kΩ, and RL must have a value of 300 Ω (that is, low drive operation only). The resistors connected to the RSET1 and RSET2 pins should have a 1% tolerance. The ADV7344 contains two compensation pins, COMP1 and COMP2. A 2.2 nF compensation capacitor should be connected from each of these pins to VAA. For applications requiring an output buffer and reconstruction filter, the ADA4430-1, ADA4411-3, and ADA4410-6 integrated video filter buffers should be considered. Table 53.

Alternatively, the ADV7344 can be used with an external voltage reference by connecting the reference source to the VREF pin. For optimal performance, an external voltage reference such as the AD1580 should be used with the ADV7344. If an external voltage reference is not used, a 0.1 μF capacitor should be connected from the VREF pin to VAA. BNC OUTPUT 560 Ω Figure 84. Example of Output Filter for SD, 16× Oversampling 4.7µH DAC OUTPUT 6.8pF 600Ω 6.8pF 600Ω 4 3 75Ω 1 BNC OUTPUT 560Ω An output buffer is necessary on any DAC that operates in low drive mode (RSET = 4.12 kΩ, RL = 300 Ω). Analog Devices, Inc. produces a range of op amps suitable for this application, for example, the AD8061. For more information about line driver buffering circuits, see the relevant op amp data sheet. An optional reconstruction (anti-imaging) low-pass filter (LPF) may be required on the ADV7344 DAC outputs if the ADV7344 is connected to a device that requires this filtering. The filter specifications vary with the application. The use of 16× (SD), 8× (ED), or 4× (HD) oversampling can remove the requirement for a reconstruction filter altogether. Figure 85.

It has been designed to minimize interference effects on the integrity of the analog circuitry by the high speed digital circuitry. It is imperative that these same design and layout techniques be applied to the system-level design so that optimal performance is achieved. The layout should be optimized for lowest noise on the ADV7344 power and ground planes by shielding the digital inputs and providing good power supply decoupling. It is recommended to use a 4-layer printed circuit board with ground and power planes separating the signal trace layer and the solder side layer. 06400-088 GAIN (dB) –40 –50 10M 100M FREQUENCY (Hz) Figure 87.

The external loop filter components and components connected to the COMP, VREF, and RSET pins should be placed as close as possible to and on the same side of the PCB as the ADV7344. Adding vias to the PCB to get the components closer to the ADV7344 is not recommended. It is recommended that the ADV7344 be placed as close as possible to the output connector, with the DAC output traces as short as possible. The termination resistors on the DAC output traces should be placed as close as possible to and on the same side of the PCB as the ADV7344. The termination resistors should overlay the PCB ground plane. External filter and buffer components connected to the DAC outputs should be placed as close as possible to the ADV7344 to minimize the possibility of noise pickup from neighboring circuitry, and to minimize the effect of trace capacitance on output bandwidth. This is particularly important when operating in low drive mode (RSET = 4.12 kΩ, RL = 300 Ω). 06400-089 GAIN (dB) –40 GROUP DELAY (Seconds) PHASE (Degrees) 10M 100M FREQUENCY (Hz) Figure 88.

For optimal performance, linear regulators rather than switch mode regulators should be used. If switch mode regulators must be used, care must be taken with regard to the quality of the output voltage in terms of ripple and noise. This is particularly true for the VAA and PVDD power domains. Each power supply should be individually connected to the system power supply at a single point through a suitable filtering device, such as a ferrite bead. –30 –40 –40 –120 1 10 FREQUENCY (MHz) 100 Figure 89.

The VAA, PVDD, VDD_IO, and both VDD pins should be individually decoupled to ground. The decoupling capacitors should be placed as close as possible to the ADV7344 with the capacitor leads kept as short as possible to minimize lead inductance. A 1 μF tantalum capacitor is recommended across the VAA supply in addition to the 10 nF and 0.1 μF ceramic capacitors. Due to the high clock rates used, avoid long clock traces to the ADV7344 to minimize noise pickup. Any pull-up termination resistors for the digital inputs should be connected to the VDD power supply. Any unused digital inputs should be tied to ground. Analog Signal Interconnect DAC output traces should be treated as transmission lines with appropriate measures taken to ensure optimal performance (for example, impedance matched traces). The DAC output traces should be kept as short as possible. The termination resistors on the DAC output traces should be placed as close as possible to and on the same side of the PCB as the ADV7344. To avoid crosstalk between the DAC outputs, it is recommended that as much space as possible be left between the traces connected to the DAC output pins. Adding ground traces between the DAC output traces is also recommended. Power Supply Sequencing The ADV7344 is robust to all power supply sequencing combinations. Any particular sequence can be used. Digital Signal Interconnect The digital signal traces should be isolated as much as possible from the analog outputs and other analog circuitry. Digital signal traces should not overlay the VAA or PVDD power planes.

ADV7344 Typical Application Circuit Rev. 0 | Page 68 of 88 ADV7344 APPENDIX 1—COPY GENERATION MANAGEMENT SYSTEM SD CGMS Subaddress 0x99 to Subaddress 0x9B The ADV7344 supports copy generation management system (CGMS) conforming to the EIAJ CPR-1204 and ARIB TR-B15 standards. CGMS data is transmitted on Line 20 of the odd fields and Line 283 of even fields. Subaddress 0x99, Bits[6:5] control whether CGMS data is output on odd or even fields or both. SD CGMS data can only be transmitted when the ADV7344 is configured in NTSC mode. The CGMS data is 20 bits long. The CGMS data is preceded by a reference pulse of the same amplitude and duration as a CGMS bit (see Figure 91). When HD CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 1080i CGMS data is applied to Line 19 and Line 582 of the luminance vertical blanking interval. The HD CGMS data registers are at Subaddress 0x41, Subaddress 0x42, and Subaddress 0x43. The ADV7344 also supports CGMS Type B packets in HD mode (720p and 1080i) in accordance with CEA-805-A. When HD CGMS Type B is enabled (Subaddress 0x5E, Bit 0 = 1), 720p CGMS data is applied to Line 23 of the luminance vertical blanking interval. When HD CGMS Type B is enabled (Subaddress 0x5E, Bit 0 = 1), 1080i CGMS data is applied to Line 18 and Line 581 of the luminance vertical blanking interval. The HD CGMS Type B data registers are at Subaddress 0x5E to Subaddress 0x6E. ED CGMS Subaddress 0x41 to Subaddress 0x43 Subaddress 0x5E to Subaddress 0x6E 525p The ADV7344 supports copy generation management system (CGMS) in 525p mode in accordance with EIAJ CPR-1204-1. When ED CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 525p CGMS data is inserted on Line 41. The 525p CGMS data registers are at Subaddress 0x41, Subaddress 0x42, and Subaddress 0x43. The ADV7344 also supports CGMS Type B packets in 525p mode in accordance with CEA-805-A. When ED CGMS Type B is enabled (Subaddress 0x5E, Bit 0 = 1), 525p CGMS Type B data is inserted on Line 40. The 525p CGMS Type B data registers are at Subaddress 0x5E to Subaddress 0x6E. CGMS CRC FUNCTIONALITY If SD CGMS CRC (Subaddress 0x99, Bit 4) or ED/HD CGMS CRC (Subaddress 0x32, Bit 7) is enabled, the upper six CGMS data bits, C19 to C14, which comprise the 6-bit CRC check sequence, are automatically calculated on the ADV7344. This calculation is based on the lower 14 bits (C13 to C0) of the data in the CGMS data registers, and the result is output with the remaining 14 bits to form the complete 20 bits of the CGMS data. The calculation of the CRC sequence is based on the polynomial x6 + x + 1 with a preset value of 111111. If SD CGMS CRC or ED/HD CGMS CRC are disabled, all 20 bits (C19 to C0) are output directly from the CGMS registers (CRC must be calculated by the user manually). If ED/HD CGMS Type B CRC (Subaddress 0x5E, Bit 1) is enabled, the upper six CGMS Type B data bits (P122 to P127) that comprise the 6-bit CRC check sequence are automatically calculated on the ADV7344. This calculation is based on the lower 128 bits (H0 to H5 and P0 to P121) of the data in the CGMS Type B data registers. The result is output with the remaining 128 bits to form the complete 134 bits of the CGMS Type B data. The calculation of the CRC sequence is based on the polynomial x6 + x + 1 with a preset value of 111111. If ED/HD CGMS Type B CRC is disabled, all 134 bits (H0 to H5 and P0 to P127) are output directly from the CGMS Type B registers (CRC must be calculated by the user manually). 625p The ADV7344 supports copy generation management system (CGMS) in 625p mode in accordance with IEC 62375 (2004). When ED CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 625p CGMS data is inserted on Line 43. The 625p CGMS data registers are at Subaddress 0x42 and Subaddress 0x43. HD CGMS Subaddress 0x41 to Subaddress 0x43 Subaddress 0x5E to Subaddress 0x6E The ADV7344 supports copy generation management system (CGMS) in HD mode (720p and 1080i) in accordance with EIAJ CPR-1204-2. When HD CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 720p CGMS data is applied to Line 24 of the luminance vertical blanking interval.

WSS data is transmitted on Line 23. WSS data can be transmitted only when the device is configured in PAL mode. The WSS data is 14 bits long. The function of each of these bits is shown in Table 55.

Closed captioning is transmitted during the blanked active line time of Line 21 of the odd fields and Line 284 of the even fields. Closed captioning consists of a 7-cycle sinusoidal burst that is frequency- and phase-locked to the caption data. After the clock run-in signal, the blanking level is held for two data bits and is followed by the Logic 1 start bit. Sixteen bits of data follow the start bit. These consist of two 8-bit bytes, seven data bits, and one odd parity bit. The data for these bytes is stored in the SD closed captioning registers (Subaddress 0x93 to Subaddress 0x94). The ADV7344 also supports the extended closed captioning operation, which is active during even fields and encoded on Scan Line 284. The data for this operation is stored in the SD closed captioning registers (Subaddress 0x91 to Subaddress 0x92). The ADV7344 automatically generates all clock run-in signals and timing that support closed captioning on Line 21 and Line 284. All pixels inputs are ignored on Line 21 and Line 284 if closed captioning is enabled. The FCC Code of Federal Regulations (CFR) 47 Section 15.119 and EIA-608 describe the closed captioning information for Line 21 and Line 284. The ADV7344 uses a single buffering method. This means that the closed captioning buffer is only 1-byte deep. Therefore, there is no frame delay in outputting the closed captioning data, unlike other 2-byte deep buffering systems. The data must be loaded one line before it is output on Line 21 and Line 284. A typical implementation of this method is to use VSYNC to interrupt a microprocessor, which in turn loads the new data (2 bytes) in every field. If no new data is required for transmission, 0s must be inserted in both data registers; this is called nulling. It is also important to load control codes, all of which are double bytes, on Line 21. Otherwise, a TV does not recognize them. If there is a message such as “Hello World” that has an odd number of characters, it is important to add a blank character at the end to make sure that the end-of-caption, 2-byte control code lands in the same field. 10.5 ± 0.25µs 12.91µs 7 CYCLES OF 0.5035MHz CLOCK RUN-IN TWO 7-BIT + PARITY ASCII CHARACTERS (DATA) S T A D0 TO D6 R T BYTE 0 P A R I T Y P A R I T Y 50 IRE D0 TO D6 40 IRE REFERENCE COLOR BURST (9 CYCLES) FREQUENCY = FSC = 3.579545MHz AMPLITUDE = 40 IRE 10.003µs 27.382µs BYTE 1 33.764µs Figure 99.

The register settings in Table 56 are used to generate an SD NTSC 75% color bar test pattern. CVBS output is available on DAC 4, S-Video (Y/C) output is on DAC 5 and DAC 6, and YPrPb output is on DAC 1 to DAC 3. Upon power-up, the subcarrier frequency registers default to the appropriate values for NTSC. All other registers are set as normal/default. Table 56. SD NTSC Color Bar Test Pattern Register Writes Subaddress 0x00 0x82 0x84 Setting 0xFC 0xC9 0x40 Note that when programming the FSC registers, the user must write the values in the sequence FSC0, FSC1, FSC2, FSC3. The full FSC value to be written is accepted only after the FSC3 write is complete. ED/HD TEST PATTERNS The ADV7344 is able to generate ED/HD color bar, black bar, and hatch test patterns. The register settings in Table 58 are used to generate an ED 525p hatch test pattern. YPrPb output is available on DAC 1 to DAC 3. All other registers are set as normal/default. Table 58.

For PAL output of either test pattern, the same settings are used, except that Subaddress 0x80 is programmed to 0x11 and the subcarrier frequency registers are programmed as shown in Table 57. Table 57.

To generate an ED 525p flat field test pattern, the same settings shown in Table 58 should be used, except that 0x0D should be written to Subaddress 0x31. The Y, Cr, and Cb levels for the hatch and flat field test patterns can be controlled using Subaddress 0x36, Subaddress 0x37, and Subaddress 0x38, respectively. For ED/HD standards other than 525p, the same settings as shown in Table 58 (and subsequent comments) are used except that Subaddress 0x30, Bits[7:3] are updated as appropriate.

All timing information is transmitted using a 4-byte synchronization pattern. A synchronization pattern is sent immediately before and after each line during active picture and retrace. If the S_VSYNC and S_HSYNC pins are not used, they should be tied high during this mode.
