Quad Lane Extender

The QLx411GRx is a settable quad receive-side equalizer with extended functionality for advanced protocols operating with line rates up to 11.3Gb/s such as InfiniBand (SDR, DDR and QDR) and 40G Ethernet (40GBase-CR4). The QLx411GRx compensates for the frequency dependent attenuation of copper twin-axial cables, extending the signal reach up to at least 10m on 28AWG cable.
