The EL9111 and EL9112 are triple channel differenTIalreceivers and equalizers. They contains three high speeddifferenTIal receivers with five programmable poles. Theoutputs of these pole blocks are then summed into an outputbuffer. The equalizaTIon length is set with the voltage on asingle pin. Using the Enable pin on the EL9111 and EL9112,the outputs can be placed into a high impedance stateenabling mulTIple devices to be connected in parallel andused in a multiplexing application.The gain can be adjusted up or down on each channel by 6dBusing its VGAIN control signal. In addition, a further 6dB of gaincan be switched in to provide a matched drive into a cable.The EL9111 and EL9112 have a bandwidth of 150MHz andconsume just 108mA on ±5V supply. A single input voltage isused to set the compensation levels for the required lengthof cable.The EL9111 is a special version of the EL9112 that decodessyncs encoded onto the common modes of three pairs ofCAT-5 cable by the EL4543. (Refer to the EL4543 datasheetfor details.)The EL9111 and EL9112 are available in a 28 Ld QFNpackage and are specified for operation over the full -40°C to+85°C temperature range.
