THS8134BCPHP

ADCs/DACs - Special Purpose Overview

The THS8134BCPHP is a triple 8-bit digital-to-analog converter (DAC) optimized for video and graphics applications. It operates at sampling rates up to 80 MSPS with a 5-V analog supply and a 3-V to 5-V digital supply. The device features current-steering outputs capable of directly driving doubly-terminated 75-Ω coaxial cables. It includes integrated circuitry for bi-level or tri-level sync generation, configurable blanking levels, and an internal voltage reference. Input formats support 3x8 bit 4:4:4, 2x8 bit 4:2:2, or 1x8 bit 4:2:2 multiplexed YPbPr/GBR data.

ADCs/DACs - Special Purpose Feature Summary

• Triple 8-bit DACs with 80 MSPS operation
• Direct drive of doubly-terminated 75-Ω loads into standard video levels
• Bi-level (EIA) or tri-level (SMPTE) sync generation with 7:3 video/sync ratio
• Configurable blanking level and internal voltage reference

ADCs/DACs - Special Purpose Applications

• High-definition television (HDTV) set-top boxes/receivers
• High-resolution image processing
• Desktop publishing
• Direct digital synthesis/I-Q modulation

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific revision suffix 'BCPHP' against the manufacturer's latest documentation to confirm temperature range and blanking level specifications. Ensure compatibility with existing board layouts using the TQFP-48 PowerPAD package. Check for end-of-life status or obsolescence notices from Texas Instruments before finalizing procurement plans.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a triple 8-bit DAC with integrated sync generation is required for video applications. Compare with the THS8133 if 10-bit resolution is needed, as it is pin-compatible. Consider the THS8134BCPHP specifically for its guaranteed K_IMBAL(SYNC) specification over the full temperature range compared to earlier revisions.

ADCs/DACs - Special Purpose Part Context

The THS8134 belongs to a family of high-speed video DACs from Texas Instruments. The BC suffix indicates a specific revision with guaranteed maximum imbalance between inserted analog syncs over the full operating temperature range. This distinguishes it from the C and A versions which have different performance guarantees regarding sync imbalance and blanking levels.

ADCs/DACs - Special Purpose Replacement Considerations

The THS8133 is noted as a pin-compatible alternative offering 10-bit resolution. No other direct replacement part numbers are explicitly confirmed in the provided source material.
