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.
