Triple Differential Receiver/Equalizer
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 VGAIN 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.

Tj is the maximum junction temperature (+150°C)
Ta is the maximum ambient temperature (+85°C)
For a QFN 28 package in a properly layout PCB heatsinking
copper area, +37°C/W θJA thermal resistance can be
achieved. To disperse the heat, the bottom heatspreader
must be soldered to the PCB. Heat flows through the
heatspreader to the circuit board copper then spreads and
converts to air. Thus the PCB copper plane becomes the
heatsink. This has proven to be a very effective technique. A
separate application note details the 28 Ld QFN. PCB
design considerations are available.
