Quad Lane Extender

QLx4300-S45

Features

• Supports data rates up to 3.125Gb/s

• Low power (78mW per channel)

• Low latency (<500ps)

The QLx4300-S45 is a settable quad receive-side

equalizer with extended functionality for advanced

protocols operating with line rates up to 3.125Gb/s such

as InfiniBand (SDR) and 10GBase-CX4. The

QLx4300-S45 compensates for the frequency dependent

attenuation of copper twin-axial cables, extending the

signal reach up to 40m on 24AWG cable.

• Four equalizers in a 4mmx7mm QFN package for

straight route-through architecture and simplified

routing

• Each equalizer boost is independently pin selectable

and programmable

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 QLx4300-S45 can each be set

to one of 32 compensation levels, providing optimal

signal fidelity for a given media and length. The

• Beacon signal support and line silence preservation

• 1.2V supply voltage

• Individual channel power-down (impedance select)

Applications

• InfiniBand (SDR)

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.

• 10GBase-CX4

• PCI Express (Gen 1)

• DisplayPort

Operating on a single 1.2V power supply, the

• XAUI

QLx4300-S45 enables per channel throughputs of up to

3.125Gb/s while supporting the lower data rates of

2.5Gb/s and 1.5Gb/s. The QLx4300-S45 uses current

mode logic (CML) inputs/outputs and is packaged in a

4mmx7mm 46 lead QFN. Individual lane impedance

select support is included for module applications.

• SAS (1.0)

• High-speed active cable assemblies

• High-speed printed circuit board (PCB) traces

Benefits

• Thinner gauge cable

• Extends cable reach greater than 3x

• Improved BER
