General Description
The EL4102C VFE (Video Front End) is designed to perform all of the input processing functions in an analog video system as well as provide analog input processing for digital video systems. The EL4102C VFE contains a 4:1 MUX input, a DC-restore amplifier and a variable gain amplifier. The MUX input can be used to select which input to use. In a digital system, the DC-restore and variable gain amplifiers allow the input signal to be positioned and scaled to give optimum A-to-D conversions results.
