DESCRIPTION
Fabricated using the revolutionary, complementary
Silicon-Germanium (SiGe) BiCom3X process, the
THS7368 is a low-power, single-supply, 2.7-V to 5-V,
six-channel integrated video buffer. It incorporates
three SDTV filters and three selectable
SD/ED/HD/Full-HD (also known as True-HD) HDTV
filters. All filters feature bypassable 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.
The THS7368 has flexible input coupling capabilities
that 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. The
ac-coupled modes include a transparent sync-tip
clamp for CVBS, Y', and G'B'R' signals. AC-coupled
biasing for C'/P'B/P'R channels can easily be achieved
by adding an external resistor to VS+.
The THS7368 is an ideal choice for all video buffer
applications. Its rail-to-rail output stage with 6-dB gain
allows for both ac and dc line driving. The ability to
drive two lines, or 75-Ω loads, allows for maximum
flexibility as a video line driver. The 23.4-mA total
quiescent current at 3.3 V and 0.1 μA (disabled
mode) makes it a good choice for systems that must
meet power-sensitive Energy Star® standards.
The THS7368 is available in a TSSOP-20 package
that is lead-free and green (RoHS-compliant).
