11.1Gb/s Lane Extender
QLx111GRx
The QLx111GRx 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 (10GBase-CR). The QLx111GRx
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 QLx111GRx 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 QLx111GRx
enables per 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 QLx111GRx uses current
mode logic (CML) input/output and is packaged in a
3mmx3mm 16 lead QFN. LOS support is included for
module applications.
