www.ti.com SBOS506A – DECEMBER 2009 – REVISED AUGUST 2012 4-Channel Video Amplifier with 1-SD and 3-HD Sixth-Order Filters and 6-dB Gain
Check for Samples: THS7373 FEATURES DESCRIPTION One SDTV Video Amplifier for CVBS Video Three HDTV Video Amplifiers for Y’/P’B/P’R,
720p/1080i/1080p30, or G’B’R’ (R’G’B’) Sixth-Order Low-Pass Filters:
– CVBS Channel: –3 dB at 9.5-MHz
– HD Channels: –3 dB at 36-MHz with 350MHz Bypass for 1080p60 Support Versatile Input Biasing:
– DC-Coupled with 300-mV Output Shift
– AC-Coupled with Sync-Tip Clamp
– Allows AC-Coupling with Biasing Built-in 6-dB Gain (2 V/V) +3-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: 16.2 mA at 3.3 V Disabled Supply Current Function: 0.1 μA Low Differential Gain/Phase: 0.15%/0.25° RoHS-Compliant Package: TSSOP-14 Fabricated using the revolutionary, complementary
Silicon-Germanium (SiGe) BiCom3X process, the
THS7373 is a low-power, single-supply, 3-V to 5-V,
four-channel integrated video buffer. It incorporates
one standard-definition (CVBS) and three highdefinition (HD) filter channels. All filters feature sixthorder Butterworth characteristics that are useful as
digital-to-analog converter (DAC) reconstruction filters
or as analog-to-digital converter (ADC) anti-aliasing
filters. The HD filters can be bypassed to support
1080p60 video or up to quad extended graphics array
(QXGA) RGB video. 1 234 As part of the THS7373 flexibility, the input can be
configured for ac-or dc-coupled inputs. The 300-mV
output level shift allows for a full sync dynamic range …
