Differential Receiver/Equalizer

The EL9110 is a single channel differential receiver and equalizer. It contains a high speed differential receiver with 5 programmable poles. The outputs of these pole blocks are then summed into an output buffer. The equalization length is set with the voltage on a single pin. The EL9110 also contains a three-statable output, enabling multiple devices to be connected in parallel and used in a multiplexing application.

The gain can be adjusted up or down by 6dB using the V

control signal. In addition, a further 6dB of gain can

GAIN

be switched in to provide a matched drive into a cable. The EL9110 has a bandwidth of 150MHz and consumes just

33mA on ±5V supply. A single input volt age is used to set the compensation levels for the required length of cable.

The EL9110 is available in the 16 Ld QSOP package and is specified for operation over the full -40°C to +85°C temperature range.
