EL4102C - Preliminary

500MHz Video Front End: 4-1 MUX, VGA & DC-Restore

Features

General Description

• 4:1 multiplexer with monitor out

• 18dB variable gain amplifier

• DC-restore amplifier

• Digital control serial interface

• ±5V operation

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.

• 500MHz bandwidth

Applications

• HDTV/DTV Analog Inputs

• Video Projectors

• Computer Monitors

• Set Top Boxes

• Security Video

• Broadcast Video Equipment

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.
