EL4102C

EL4102C - Preliminary EL4102C - Preliminary 500MHz Video Front End: 4-1 MUX, VGA & DC-Restore Features 4:1 multiplexer with monitor out 18dB variable gain amplifier DC-restore amplifier Digital control serial interface ±5V operation 500MHz bandwidth 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. In an analog system these perform the brightness and contrast operations. A buffered output of the MUX selection is also available for use as a monitor output. With a 500MHz bandwidth and only 50mA supply current, the EL4102C is ideal for use in portable and fixed projectors, as well as HDTV, DTV and other high performance video applications. A 3-wire digital interface enables full control of the input selection, as well as 0 to -18dB of gain and blanking operations. The EL4102C is available in the QSOP24 package and is specified for operation over the -40°C to +85°C temperature range.
