DESCRIPTION

Fabricated using the revolutionary complementary

Silicon-Germanium (SiGe) BiCom3X process, the

THS7375 is a low-power, single-supply, 3 V to 5 V

four-channel integrated video buffer. It incorporates a

sixth-order Butterworth filter (able to be bypassed)

that is useful as a digital-to-analog converter (DAC)

reconstruction filter or an analog-to-digital converter

(ADC) anti-aliasing filter. The 9.5-MHz filter is a

perfect choice for SDTV video that includes composite (CVBS), S-video, Y'U'V', G'B'R' (R'G'B'),

Y'P'BP'R 480i/576i, and SCART systems.

As part of the THS7375 flexibility, the input can be

configured for either ac or dc-coupled inputs. The

320-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 with

sync. AC-coupled biasing for C'/P'B/P'R channels can

easily be achieved by adding an external resistor to

VS+.

The THS7375 is the perfect choice for all video buffer

applications. Its rail-to-rail output stage with 5.6-V/V

gain allows for both ac and dc line driving. This

architecture makes the THS7375 an ideal choice for

DaVinci™ processors. The ability to drive two lines

per channel, or 75-Ω loads, allows for maximum

flexibility as a video line driver. The 9.8-mA total

quiescent current at 3.3 V and 0.1-mA disabled

current makes it an excellent choice for

USB-powered, portable, or other power-sensitive

applications.

The THS7375 is available in a TSSOP-14 package

that is lead-free and green (RoHS) compliant.
