DATASHEET QLX4600-S30 FN6979 Rev 2.00 Quad Lane Extender June 23, 2016 The QLX4600-S30 is a settable quad receive-side equalizer Features with extended functionality for advanced protocols operating Supports data rates up to 6.25Gb/s with line rates up to 6.25Gb/s such as DisplayPort v1.2 (HBR1/2), InfiniBand (SDR and DDR), PCI Express and Low power (78mW per channel) 10GBase-CX4. The QLX4600-S30 compensates for the Low latency (<500ps) frequency dependent attenuation of copper twin-axial cables, Four equalizers in a 4mmx7mm TQFN package for straight extending the signal reach up to 30m on a 24AWG cable. route-through architecture and simplified routing The small form factor, highly-integrated quad design is ideal Each equalizer boost is independently pin selectable and for high-density data transmission applications including programmable active copper cable assemblies. The four equalizing filters within the QLX4600-S30 can each be set to one of 32 Beacon signal support and line silence preservation compensation levels, providing optimal signal fidelity for a Channel power-down for each equalizer given media and length. The compensation level for each filter 1.2V supply voltage can be set by either (a) three external control pins or (b) a serial bus interface. When the external control pins are used, Applications 18 of the 32 boost levels are available for each channel. If the serial bus is used, all 32 compensation levels are available. DisplayPort v1.2 active copper cable modules Operating on a single 1.2V power supply, the QLX4600-S30 InfiniBand (SDR and DDR) enables per channel throughputs of up to 6.25Gb/s while 10GBase-CX4 supporting lower data rates including 5, 4.25, 3.125 and PCI Express Gen 1 and 2 2.5Gb/s. The QLX4600-S30 uses Current Mode Logic (CML) inputs/outputs and is packaged in a 4mmx7mm 46 Ld TQFN. XAUI and RXAUI, SAS (1.0 and 2.0) Individual channel power-down support is included for PCI High-speed active cable assemblies Express applications.
