Description
General part information
THS7315 Series
Fabricated using the revolutionary complementary silicon-sermanium (SiGe) BiCom3 process, the THS7315 is a low-power, single-supply, 3-V to 5-V 3-channel integrated video buffer. It incorporates a 5th-order Butterworth filter that is useful as a digital-to-analog converter (DAC) reconstruction filter or an analog-to-digital converter (ADC) anti-aliasing filter. The 8.5-MHz filter is a perfect choice for SDTV video, including Composite Video Baseband Signals (CVBS), S-Video, Y’U’V’, G’B’R’ (R’G’B’), and Y’P’BP’R480i/576i.
The THS7315 inputs can be either ac- or dc-coupled. The 230-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 bottom-level sync. AC-coupled biasing for C'/P'B/P'Rchannels can easily be achieved by adding an external resistor to VS+.
The THS7315 is the perfect choice for all output buffer applications. Its rail-to-rail output stage with 5.2-V/V gain allows for both ac and dc line driving, making it a perfect choice for DaVinci processors. The ability for each channel to drive two video lines, or 75-loading, allows for maximum flexibility as a video line driver. The 15.6-mA quiescent current at 3.3 V also makes it an excellent choice for USB-powered, portable, or other power-sensitive video applications
