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.

Features

• Supports data rates up to 11.3Gb/s

• Low power (135mW per channel)

• Low latency (<500ps)

• Four equalizers in a 4mmx7mm QFN package for straight route-through architecture and simplified routing

• Each equalizer boost is independently pin selectable

• Supports 64b/66b encoded data – long run lengths

• Line silence preservation

• 1.2V supply voltage

• Individual lane LOS support

Applications

• QSFP active copper cable modules

• InfiniBand SDR, DDR and QDR

• 40G Ethernet (40GBase-CR4)

• XAUI and RXAUI

• High-speed active cable assemblies

• High-speed printed circuit board (PCB) traces

Benefits

• Thinner gauge cable

• Extends cable reach greater than 3x

• Improved BER
