Quad Lane Extender
ISL36411
The ISL36411 is a settable quad receive-side equalizer
with extended functionality for advanced protocols
operating with line rates up to 11.1Gbps such as
InfiniBand (QDR) and 40G Ethernet (40GBase-CR4/
SR4). The ISL36411 compensates for the frequency
dependent attenuation of copper twin-axial cables,
extending the signal reach up to at least 10m on 28AWG
cable.
The small form factor, highly-integrated quad design is
ideal for high-density data transmission applications
including active copper cable assemblies. The four
equalizing filters within the ISL36411 can each be set to
provide optimal signal fidelity for a given media and
length. The compensation level for the filters is set by
two external control pins.
Operating on a single 1.2V power supply, the ISL36411
enables per channel throughputs of 10Gbps to 11.1Gbps
while supporting lower data rates including 8.5, 6.25, 5,
4.25, 3.125, and 2.5Gbps. The ISL36411 uses current
mode logic (CML) inputs/outputs and is packaged in a
4mmx7mm 46-lead QFN. Individual lane LOS support is
included for module applications.
