Fabricated using the new complimentary silicon-germanium (SiGe) BiCom-III process, the THS7313 is a low-power, single-supply 2.7-V to 5-V, 3-channel integrated video buffer. It incorporates a 5th order Butterworth filter which is useful as a digital-to-analog converter (DAC) reconstruction filter or an analog-to-digital converter (ADC) anti-aliasing filter. The 8-MHz filter is a perfect choice for SDTV video which includes composite (CVBS), S-Video, Y'U'V', G'B'R', and Y'P'BP'R 480i/576i.
Each channel of the THS7313 is individually I2C configurable for all functions which makes it flexible for any application. Its rail-to-rail output stage allows for both ac and dc coupling applications. The 6-dB gain along with the built-in SAG correction allows for maximum flexibility as an output video buffer.
The 16.6 mA total quiescent current at 3.3 V (55 mW) makes it an excellent choice for USB powered or portable video applications. While fully disabled, the THS7313 consumes less than 1 µA.
The THS7313 is available in a small lead-free and RoHS compliant TSSOP-20 package.
As part of the THS7313 flexibility, the 2:1 MUX input can be selected for ac or dc coupled inputs. The ac coupled modes include a sync-tip clamp option for CVBS or Y' signals, or a fixed bias for the C/P'B/P'R channels. The dc input options include a dc input or a dc + 135-mV input offset shift to allow for a full sync dynamic range at the output with 0-V input.
