Description

The ISL59910 and ISL59913 are triple channel differential receivers and equalizers. They each contain 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. The ISL59910 and ISL59913 output can also be put into a high impedance state, enabling multiple devices to be connected in parallel and used in multiplexing application.

The gain can be adjusted up or down on each channel by 6dB using its V_GAIN control signal. In addition, a further 6dB of gain can be switched in to provide a matched drive into a cable.

The ISL59910 and ISL59913 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 ISL59910 is a special version of the ISL59913 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 ISL59910 and ISL59913 are available in a 28 Ld QFN package and are specified for operation over the full -40°C to +85°C temperature range.
