QLX111GRX

11.1Gb/s Lane Extender

Product Status: Mass Production

OVERVIEW

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.
