The QLx4600-SL30 is a settable quad receive-side equalizer with extended functionality for advanced protocols operating with line rates up to 6. 25Gb/s such as 4k video capable DisplayPort v1. 2 (HBR1/2), InfiniBand (SDR and DDR) and 10GBase-CX4. The QLx4600-SL30 compensates for the frequency dependent attenuation of copper twin-axial cables, extending the signal reach up to 30m on 24AWG cable. The small form factor, highly-integrated quad design is ideal for high-density data transmission applications including active copper cable assemblies. The four equalizing filters within the QLx4600-SL30 can each be set to one of 32 compensation levels, providing optimal signal fidelity for a given media and length. The compensation level for each filter can be set by either (a) three external control pins or (b) a serial bus interface. When the external control pins are used, 18 of the 32 boost levels are available for each channel. If the serial bus is used, all 32 compensation levels are available. Operating on a single 1. 2V power supply, the QLx4600-SL30 enables per channel throughputs of up to 6. 25Gb/s while supporting lower data rates including 5, 4. 25, 3. 125 and 2. 5Gb/s. The QLx4600-SL30 uses Current Mode Logic (CML) inputs/outputs and is packaged in a 4mmx7mm 46 Ld QFN. Individual lane LOS support is included for module applications.
