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.
