描述
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.
