The device operates from a 5-V analog supply and a 3-V to 5-V range digital supply. The THS8134 has a sampling rate up to 80 MSPS. The device consists of three 8-bit D/A converters and additional circuitry for bi-level/tri-level sync and blanking level generation in video applications. THS8134 is also well-suited in applications where multiple well-matched and synchronously operating DACs are needed; for example, I-Q modulation and direct-digital synthesis in communications equipment. The current-steering DACs can be directly terminated in resistive loads to produce voltage outputs. The device provides a flexible configuration of maximum output current drive. Its output drivers are specifically designed to produce standard video output levels when directly connected to a single-ended doubly-terminated 75 Ω coaxial cable. Full-scale video/sync is generated in a 7:3 ratio, compliant with SMPTE standards for GBR and YPbPr signals. Furthermore, the THS8134 can generate both a traditional bi-level sync or a tri-level sync signal, as per the SMPTE standards, via a digital control interface. The sync signal is inserted on one of the analog output channels (sync-on-green/luminance) or on all output channels. Also, a blanking control signal sets the outputs to defined levels during the nonactive video window. The position of this defined (blanking) level and the temperature range, over which the maximum imbalance between the inserted analog syncs (KIMBAL(SYNC)), are the only differences between the unrev, revA, and revB device versions.

The second rising edge on CLK after a transition on SYNC latches M2. The interpretation is dependent on the polarity of the last SYNC transition: SYNC L to H: latched as M2_INT SYNC H to L: latched as INS3_INT Together with M1, M2_INT configures the device as shown in Table 1. When INS3_INT is high, the sync output is inserted on all DAC outputs; a low will insert it only on the AGY output. See also Figure 2 and Table 2. The value of M2 at power-up is undetermined. Therefore at least 1 L → H transition on SYNC is required to set M2. M2 48 NC 9, 10, 13, 14, 35, 36 RPr0−RPr7 15−22 I Red or Pr pixel data input bus. Index 0 denotes the least significant bit. Refer to functional description for different operating modes. SYNC 24 I Sync control input, active low. A rising edge on CLK latches SYNC. When asserted, only the AGY output (INS3_INT=L, see terminal M2) or ARPr, AGY and ABPb outputs (INS3_INT=H, see terminal M2) are driven to the sync level, irrespective of the values on the data or BLANK inputs. Consequently, SYNC should remain low for the whole duration of sync, which is in the case of a tri-level sync both the negative and positive portion (see Figure 7). SYNC_T 25 I Sync tri-level control, active high. A rising edge on CLK latches SYNC_T. When asserted, a positive sync (higher than blanking level) is generated when SYNC is low. When disabled, a negative sync (lower than blanking level) is generated when SYNC is low. When generating a tri-level (negative-to-positive) sync, a L → H transition on this signal positions the start of the positive transition. See Figure 6 for timing control. VREF 37 I/O Not connected The value on SYNC_T is ignored when SYNC is not asserted (high). Voltage reference for DACs. An internal voltage reference of nominally 1.35 V is provided, which requires an external 0.1 µF ceramic capacitor between VREF and AVSS. However, the internal reference can be overdriven by an externally supplied reference voltage. • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 • 3

 SLVS205D − MAY 1999 − REVISED MARCH 2000 functional description device configuration Input data to the device can be supplied from a 3x8b GBR/YPbPr input port. If the device is configured to take data from all three channels, the data is clocked in at each rising edge of CLK. All three DACs operate at the full clock speed of CLK. In the case of 4:2:2 sampled data (for YPbPr) the device can be fed over either a 2x8 bit or 1x8 bit multiplexed input port. An internal demultiplexer will route input samples to the appropriate DAC: Y at the rate of CLK, Pb and Pr each at the rate of one-half CLK. According to ITU-BT.656, the sample sequence is Pb-Y-Pr over a 1x8 bit interface (Y-port). The sample sequence starts at the first rising edge of CLK after BLANK has been taken high (inactive). In this case the frequency of CLK is two times the Y conversion speed and four times the conversion speed of both Pr and Pb. With a 2x8 bit input interface, both the Y-port and the Pr-port are sampled on every CLK rising edge. The Pr-port carries the sample sequence Pb-Pr. The sample sequence starts at the first rising edge of CLK after BLANK has been taken high (inactive). In this case the frequency of CLK is equal to the conversion speed of Y and 2x the conversion speed of both Pr and Pb. The device’s operation mode is set by the M1 and M2 mode selection terminals, according to Table 1. The operation mode also determines the blanking level, as explained below in the sync/blanking generation sections. Table 1.

Data clocked in on each rising edge of CLK from Y & Pr input channels. A sample sequence of Pb−Pr−... should be applied to the Pr port. At the first rising edge of CLK after BLANK is taken high, Pb should be present on this port. For the definition of the analog output levels during blanking, see note 1. H H YPbPr 1x8b−4:2:2 YPbPr mode 4:2:2 1x8 bit (ITU-BT.656 compliant). Data clocked in on each rising edge of CLK from Y input channel. For the definition of the analog output levels during blanking, see note 1. NOTE 1: In all device versions, the blanking level on the AGY channel output corresponds to input code 0 of the DAC. • • In the THS8134CPHP and the THS8134ACPHP versions, the blanking level on the ABPb and ARPr channel outputs corresponds to the 128 input code of the DAC, when sync is inserted on all three channels (INS3_INT=H), and to the 0 input code of the DAC, when sync is only inserted on the Y channel (INS3_INT=L). In the THS8134BCPHP version, the blanking level on the ABPb and ARPr channel outputs corresponds to the 128 input code of the DAC irrespective if sync is inserted on all three channels (INS3_INT=H), or if sync is inserted only on the Y channel (INS3_INT=L). • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 • 5

By combining the SYNC and SYNC_T control inputs, either bi-level negative going pulses or tri-level pulses can be generated. Depending on the timing controls for these signals, both horizontal and vertical sync signals can be generated. Assertion of SYNC (active low) will identify the sync period, while assertion of SYNC_T (active high) within this period will identify the positive excursion of a tri-level sync. Refer to the application information section for practical examples on the use of these control inputs for sync generation. blanking generation An additional control input BLANK is provided that will fix the output amplitude on all channels to the blanking level, irrespective of the value on the data input ports. However, sync generation has precedence over blanking; that is, if SYNC is low, the level of BLANK is don’t care. The absolute amplitude of the blanking level with respect to active video is determined by the GBR or YPbPr operation mode of the device. Refer to the application information section for practical examples on the use of this control input for blank generation. Figure 6 shows how to control SYNC, SYNC_T, and BLANK signals to generate tri-level sync levels and blanking at the DAC output. A bi-level (negative) sync is generated similarly by avoiding the positive transition on SYNC_T during SYNC low. 8 • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 •

Sync and Blanking Generation DAC operation The analog output drivers generate a current of which the drive level can be user-modified by choice of an appropriate resistor value RFS, connected to the FSADJ terminal. Refer to the paragraph on output amplitude control for details on how the output drive is affected by the operation mode of the device. All current sources derive their amplitudes from an internal generator that produces a 1.35 V reference level. All current source amplitudes (video, blanking, sync) also come from this reference so that the relative amplitudes of sync/blank/video are always equal to their nominal relationships. For increased stability on the absolute levels, the user can overdrive the reference by directly driving the VREF input terminal. output amplitude control The current drive on all three output channels and on the internal sync generator is controlled by a resistor RFS that must be connected between FSADJ and AVSS. In all operation modes the relative amplitudes of the current drivers are maintained irrespective of the RFS value, as long as a maximum current drive capability is not exceeded. The sync generator is composed of different current sources that are internally routed to a corresponding DAC output. Depending on the setting of INS3_INT during SYNC low, the sync current drive is added to either only the green channel output (sync-on-green) if INS3_INT = L or all three channel outputs INS3_INT = H. In either case the relative current levels, as defined below, are maintained. • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 • 9 

 

   
      
 

  
 SLVS205D − MAY 1999 − REVISED MARCH 2000 output amplitude control (continued) The exact relationship between RFS and the current drive level on each channel is dependent on the operation mode of the device (see Table 4). In GBR mode, the output drive is identical on the three channels, while in YPbPr mode, a level shift is implemented on Pb and Pr channels. Refer to the application information section for details on the current drive levels in each mode. The device has an internal voltage reference derived from a bandgap reference of 1.35 V. The relationship between the full-scale current drive level and RFS is given by: IFS [A] = α x VREF [V] ÷ RFS [Ω] where α is dependent on the operation mode of the device. Typical operation modes are shown in Table 4 for the nominal RFS value. This value will produce the full-scale current levels mentioned in Table 4 and, when terminated, voltages of standard video levels, as shown in the applications section. The resistor value is variable provided the maximum current level on each of the DAC outputs is not exceeded. Table 4.

The total DAC output variation (device droop) consists of this and an additional amount (excess droop) caused by the output impedance of the device, as shown in Table 5. • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 • 13

The scanning structure is typically 525 lines, 59.94 fields, 2:1 interlace and 4:3 or 16:9 aspect ratio. The analog signals of this standard are suitable for the generation of, or they can be generated from, digital video signals compliant to SMPTE 125M and SMPTE 267M by A/D or D/A conversion respectively.

The green signal has a negative-going sync pulse of amplitude 300 mV from blanking level. The dc offset, as defined by the blanking level of the signal, is 0.0 V ±1.0 V.

 SLVS205D − MAY 1999 − REVISED MARCH 2000 APPLICATION INFORMATION SMPTE 253M (continued) BLANK can be tied high in this mode if the data input is kept to 00h during the blanking time, since black and blanking level are at identical levels. Furthermore the SYNC_T terminal remains low, since only a bi-level sync is generated. SMPTE 274M This standard defines a raster scanning format of 1920×1080 pixels inside a total raster of 1125 lines and an aspect ratio of 16:9, GBR and YPbPr color encoding formats and both analog and digital interfaces for GBR and YPbPr formats. With respect to the analog interface, SMPTE 274M defines the position of the start of each line at the positive zero-crossing of a tri-level sync pulse. The sync pulse has a negative-going transition on a fixed number of clock cycles preceding this instant and another negative transition on a fixed number of clock cycles following this instant, as shown in Figure 13. The positive peak of sync is 300 mV; the negative peak of sync –300 mV. The interface can carry both GBR o and YPbPr signals. The tri-level horizontal sync is inserted on all analog outputs and has identical absolute amplitude levels in all cases. For Y, black corresponds to a level of 0 V and peak white is 700 mV. Pb and Pr, on the other hand, have amplitudes between –350 mV and 350 mV. The relative amplitudes of the current sources are identical to the case of SMPTE 253M. However, in this case a tri-level sync needs to be generated instead of a bi-level negative sync, and it needs to be present on all three component outputs. THS8134 supports the tri-level sync via an additional internal current source, activated by asserting SYNC_T. The sync insertion on all outputs is under the control of the INS3_INT pin. When asserted (high), the sync is inserted on all three output channels. 0H 44T 44T Analog Waveform (Y’R’G’B’) Duration in Reference Clock period 1920T Figure 13.

Figure 14 shows the relative amplitudes of video and horizontal/vertical sync. The level of vertical sync (broad pulse) is identical to the negative excursion of horizontal sync and therefore can be generated by the same current source on THS8134 by appropriately asserting the sync control inputs. 18 • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 •

 SLVS205D − MAY 1999 − REVISED MARCH 2000 APPLICATION INFORMATION SMPTE 274M (continued) In the YPbPr mode of this standard, the sync is centered around the center span of the video amplitude levels, as shown in Figure 14. So the current for Pb and Pr is down-shifted with respect to Y to accommodate the minimum data level at 0 mA. Thus, an input code of 00h corresponds now to an output drive of 0 mA while the negative sync level is at 1.33 mA, corresponding to 50 mV. The Pb and Pr data input format is offset binary. Table 10 lists the THS8134 full-scale output currents for Pb and Pr channels in the YPbPr operation mode of the device. The operation mode corresponds to YPbPr with sync-on-all of Table 1. Table 10.

Therefore, for the generation of output signals compliant to this standard, refer to the configuration of THS8134 for SMPTE 274M. 20 • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 •

RS-343 uses a bi-level negative going sync. Also, there is a difference between the reference blanking and black video level. Figure 15 shows the relative amplitudes and the current drives that would be needed to generate compliant relative amplitudes with a double-terminated 75-Ω load, as is specified for RS-343. RS-170 compliant levels can be reached using the same current sources but a different 150-Ω source termination resistor, which brings the load to 150 || 75 Ω = 50 Ω. In this case a blank-to-white level of approximately 1 V is reached (0.714 V × 50 ÷ 37.5) as required by RS-170.

Use of the PowerPAD package does not require any special considerations except to note that the PowerPAD, 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, solder masks (or other assembly techniques) may be required to prevent any inadvertent shorting by the exposed PowerPAD 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 below. Although the actual size of the exposed die pad may vary, the minimum size required for the keep-out area for the 48-pin PHP PowerPAD package is 7 mm × 7 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 will vary 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. More information on this package and other requirements for using thermal lands and thermal vias are detailed in the TI application note PowerPAD Thermally Enhanced Package Application Report, TI literature number SLMA002, available via the TI Web pages beginning at URL: http://www.ti.com. • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 • 21 

 

   
      
 

  
 SLVS205D − MAY 1999 − REVISED MARCH 2000 APPLICATION INFORMATION designing with PowerPAD (continued) For the THS8134, this thermal land should 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 should be as large as possible without shorting device signal terminals. The thermal land may be soldered to the exposed PowerPAD 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.
