DESCRIPTION
●Fabricated using the Silicon-Germanium (SiGe) BiCom-III process, the THS7314 is a low power single-supply 3-V to 5-V 3-channel integrated video buffer. It incorporates a 5th-order Butterworth filter which is useful as a DAC reconstruction filter or an ADC anti-aliasing filter. The 8.5-MHz filter is a perfect choice for SDTV video which includes Composite (CVBS), S-Video, Y"U"V", G"B"R" (R"G"B"), and Y"P"BP"R 480i/576i.
●FEATURES
