A new family of differential receiver/equaliser ICs can handle video over Cat5 cable applications at distances typically up to 300m

The Elantec EL9110 is the first device in Intersil's new family of differential receivers/equalisers designed specifically for equalising video signals in video switching. The EL9110 features a 150MHz bandwidth at -3dB and consumes only 33mA from a 5V power supply. It can be used for twisted-pair receiving, VGA over twisted-pair and security video applications and features tristateable outputs allowing multiple devices to be used in video multiplexing applications.

Intersil has many years experience in high performance analogue and op amp development and the new device family uses this expertise to provide the high performance, low power consumption and reliability required by designers of advanced video switches.

The EL9110 contains a high-speed differential receiver with five programmable poles.

The outputs of these pole blocks are summed into an output buffer.

Equalisation length is set by the voltage on a single pin.

It also provides a tristateable output, enabling multiple devices to be used in a multiplexing application.

Gain can be adjusted up or down by 6dB using a voltage gain control signal.

An additional 6dB of gain can be switched in to provide a matched drive into a cable.

The EL9110 operates over the full -40 to +85C temperature range.
