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 id……
