11.1Gb/s Lane Extender

ISL36111

The ISL36111 is a settable single-channel receive-side

equalizer with extended functionality for advanced

protocols operating with line rates up to 11.1Gb/s such

as 10G Ethernet. The ISL36111 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 design is ideal

for high-density data transmission applications including

active copper cable assemblies. The equalizing filter

within the ISL36111 can be set to provide optimal signal

fidelity for a given media and length. The compensation

level for the filter is set by two external control pins.

Operating on a single 1.2V power supply, the ISL36111

enables channel throughputs of 10Gb/s to 11.1Gb/s

while supporting lower data rates including 8.5, 6.25, 5,

4.25, 3.125, and 2.5Gb/s. The ISL36111 uses current

mode logic (CML) input/output and is packaged in a

3mmx3mm 16 lead QFN. The device supports LOS

functionality for module applications.
