Triple Differential Receiver/Equalizer
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 V
GAIN
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.
