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 con-
versions 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.
