Quad Lane Extender
QLx4600-SL30
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.
Features
• Supports data rates up to 6.25Gb/s
• Low power (78mW 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 and
programmable
• Beacon signal support and line silence preservation
• 1.2V supply voltage
• Individual lane LOS support
Applications
• DisplayPort v1.2 active copper cable modules
• QSFP active copper cable modules
• InfiniBand (SDR and DDR)
• 10GBase-CX4
• XAUI and RXAUI, SAS (2.0)
• High-speed Printed Circuit Board (PCB) traces
Benefits
• Thinner gauge cable
• Extends cable reach greater than 3x
• Improved BER

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
4. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
