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.
