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 VS+.

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).
