It incorporates • Sixth-Order Low-Pass Filters: one SDTV filter and three fixed Full-HD (also known as True-HD) HDTV filters. All filters feature – SD Channel: –3 dB at 9.5 MHz sixth-order Butterworth characteristics that are useful – Fixed Full-HD Channels: –3 dB at 72 MHz as digital-to-analog converter (DAC) reconstruction • Versatile Input Biasing: filters or as analog-to-digital converter (ADC) anti-aliasing filters. – DC-Coupled with 300-mV Output Shift – AC-Coupled with Sync-Tip Clamp or Bias The THS7372 has flexible input coupling capabilities, and can be configured for either ac- or dc-coupled • Built-in 6-dB Gain (2 V/V) inputs. The 300-mV output level shift allows for a full • +2.7-V to +5-V Single-Supply Operation sync dynamic range at the output with 0-V input. • Rail-to-Rail Output: AC-coupled modes include a transparent sync-tip clamp for CVBS, Y', and G'B'R' signals. AC-coupled – Output Swings within 100 mV from the biasing for P'B/P'R channels can easily be achieved Rails: Allows AC or DC Output Coupling by adding an external resistor to VS+. – Supports Driving Two Video Lines/Channel The THS7372 is an ideal choice for a wide range of • Low Total Quiescent Current: 23.4 mA at 3.3 V video buffer applications. Its rail-to-rail output stage • Disabled Supply Current Function: 0.1 μA with 6-dB gain allows for both ac and dc line driving. • Low Differential Gain/Phase: 0.2%/0.35 ° The ability to drive two lines, or 75- Ω loads, allows for maximum flexibility as a video line driver. The • RoHS-Compliant TSSOP-14 Package 23.4-mA total quiescent current at 3.3 V and 0.1 μA (disabled mode) makes it well-suited for systems that APPLICATIONS must meet power-sensitive Energy Star® standards. • Set Top Box Output Video Buffering The THS7372 is available in a TSSOP-14 package • PVR/DVDR Output Buffering that is lead-free and green (RoHS-compliant). • BluRay ™ Output Video Buffering Single-Supply, DC-Input/DC-Output Coupled Video Line Driver 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 BluRay is a trademark of Blu-ray Disc Association (BDA). 3 Energy Star is a registered trademark of Energy Star. 4 Macrovision is a registered trademark of Macrovision Corporation. 5 All other trademarks are the property of their respective owners.
