October 26, 2009 11.1Gb/s Lane Extender
The QLx111GRx is a settable single-channel receiveside 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 …
