The first device in a new family of differential receiver/equaliser ICs designed capable of handling video over CAT-5 cable applications at distances typically up to 305 metres, the Elantec EL9110, has been released by Intersil.
Designed specifically for equalising video signals in video switching, the EL9110 features 150 MHz of bandwidth at -3dB and consumes only 33 mA from a 5 V power supply. It can be used for twisted-pair receiving, VGA over twisted-pair and security video applications and features tri-stateable outputs allowing multiple devices to be used in video multiplexing applications.
Intersil has many years experience in high performance analog 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 tri-stateable output, enabling multiple devices to be used in a multiplexing application. Gain can be adjusted up or down by 6 dB using a voltage gain control signal. An additional 6 dB of gain can be switched in to provide a matched drive into a cable.
