It incorporates • Sixth-Order Low-Pass Filters: one standard-definition (CVBS) and three – CVBS Channel: –3 dB at 9.5-MHz high-definition (HD) filter channels. All filters feature sixth-order Butterworth characteristics that are useful – HD Channels: –3 dB at 36-MHz with as digital-to-analog converter (DAC) reconstruction 350-MHz Bypass for 1080p60 Support filters or as analog-to-digital converter (ADC) • Versatile Input Biasing: anti-aliasing filters. The HD filters can be bypassed to – DC-Coupled with 300-mV Output Shift support 1080p60 video or up to quad extended graphics array (QXGA) RGB video. – AC-Coupled with Sync-Tip Clamp – Allows AC-Coupling with Biasing As part of the THS7373 flexibility, the input can be configured for ac- or dc-coupled inputs. The 300-mV • Built-in 6-dB Gain (2 V/V) output level shift allows for a full sync dynamic range • +3-V to +5-V Single-Supply Operation at the output with 0-V input. The ac-coupled modes • Rail-to-Rail Output: include a transparent sync-tip clamp option for composite video (CVBS), Y', and G'B'R' signals. – Output Swings Within 100 mV from the AC-coupled biasing for C'/P'B/P'R channels can easily Rails: Allows AC or DC Output Coupling be achieved by adding an external resistor to VS+. – Supports Driving Two Video Lines/Channel The THS7373 rail-to-rail output stage with 6-dB gain • Low Total Quiescent Current: 16.2 mA at 3.3 V allows for both ac and dc line driving. The ability to • Disabled Supply Current Function: 0.1 μA drive two lines, or 75- Ω loads, allows for maximum • Low Differential Gain/Phase: 0.15%/0.25° flexibility as a video line driver. The 16.2-mA total quiescent current at 3.3 V and 0.1 μA (disabled • RoHS-Compliant Package: TSSOP-14 mode) makes it an excellent choice for power-sensitive video applications. APPLICATIONS The THS7373 is available in a small TSSOP-14 • Set Top Box Output Video Buffering package that is lead-free and green • PVR/DVDR/ BluRay™ Output Buffering (RoHS-compliant). • Low-Power Video Buffering Figure 1.
