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.
