DATASHEET

The EL9111 and EL9112 are triple channel differential receivers and equalizers. They contains three high speed differential receivers with five 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. Using the Enable pin on the EL9111 and EL9112, the outputs can be placed into a high impedance state enabling multiple devices to be connected in parallel and used in a multiplexing application.
The gain can be adjusted up or down on each channel by 6dB using its VGAIN control signal. In addition, a further 6dB of gain can be switched in to provide a matched drive into a cable.
The EL9111 and EL9112 have a bandwidth of 150MHz and consume just 108mA on ±5V supply. A single input voltage is used to set the compensation levels for the required length of cable.
The EL9111 is a special version of the EL9112 that decodes syncs encoded onto the common modes of three pairs of CAT-5 cable by the EL4543. (Refer to the EL4543 datasheet for details.)
The EL9111 and EL9112 are available in a 28 Ld QFN package and are specified for operation over the full -40°C to +85°C temperature range.
