DESCRIPTION
Fabricated using the revolutionary, complementary
Silicon-Germanium (SiGe) BiCom3X process, the
THS7360 is a low-power, single-supply, 2.7-V to 5-V,
six-channel integrated video buffer. It incorporates
three SDTV filter channels and three selectable filter
(SF) channels with SD/ED/HD/Full-HD (also known
as True-HD) HDTV filtering. 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.
The THS7360 also has flexible input coupling
capabilities that can be configured for either ac- or
dc-coupled inputs. The 120-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 option 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 V_S+.
The THS7360 is an ideal choice for all video buffer
applications. Its rail-to-rail output stage with 5.6-V/V
gain (for SD channels) and 4.5-V/V gain (for SF
channels) 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
24.5-mA total quiescent current at 3.3 V and 0.1 mA
(disabled mode) makes it a good choice for systems
that must meet power-sensitive Energy Star^®
standards.
The THS7360 is available in a TSSOP-20 package
that is lead-free and green (RoHS-compliant).
