SBOS578 – AUGUST 2011 www.ti.com 4-Channel Video Amplifier with One CVBS and Three Full-HD Filters with 6-dB Gain
Check for Samples: THS7372 FEATURES DESCRIPTION One SDTV Video Amplifier for CVBS Video Three Fixed Full-HD 1080p60 Filters for
Y’/P’ B/P’ R, G’B’R’, or Computer RGB Outputs Sixth-Order Low-Pass Filters:
– SD Channel: –3 dB at 9.5 MHz
– Fixed Full-HD Channels: –3 dB at 72 MHz Versatile Input Biasing:
– DC-Coupled with 300-mV Output Shift
– AC-Coupled with Sync-Tip Clamp or Bias Built-in 6-dB Gain (2 V/V) +2.7-V to +5-V Single-Supply Operation Rail-to-Rail Output:
– Output Swings within 100 mV from the
Rails: Allows AC or DC Output Coupling
– Supports Driving Two Video Lines/Channel Low Total Quiescent Current: 23.4 mA at 3.3 V Disabled Supply Current Function: 0.1 μA Low Differential Gain/Phase: 0.2%/0.35° RoHS-Compliant TSSOP-14 Package Fabricated using the revolutionary, complementary
Silicon-Germanium (SiGe) BiCom3X process, the
THS7372 is a low-power, single-supply, 2.7-V to 5-V,
four-channel integrated video buffer. It incorporates
one SDTV filter and three fixed Full-HD (also known
as True-HD) HDTV filters. All filters feature
sixth-order Butterworth characteristics that are useful
as digital-to-analog converter (DAC) reconstruction
filters or as analog-to-digital converter (ADC)
anti-aliasing filters. 1 2345 The THS7372 has flexible input coupling capabilities,
and can be configured for either ac-or dc-coupled
inputs. The 300-mV output level shift allows for a full
sync dynamic range at the output with 0-V input. …
