Quad Lane Extender
QLx411GRx
The QLx411GRx is a settable quad receive-side equalizer
with extended functionality for advanced protocols
operating with line rates up to 11.3Gb/s such as
InfiniBand (SDR, DDR and QDR) and 40G Ethernet
(40GBase-CR4). The QLx411GRx 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 quad design is
ideal for high-density data transmission applications
including active copper cable assemblies. The four
equalizing filters within the QLx411GRx can each be set
to provide optimal signal fidelity for a given media and
length. The compensation level for each filter is set by
two external control pins.
Operating on a single 1.2V power supply, the QLx411GRx
enables per channel throughputs of 10Gb/s to 11.3Gb/s
while supporting lower data rates including 8.5, 6.25, 5,
4.25, 3.125, and 2.5Gb/s. The QLx411GRx uses current
mode logic (CML) inputs/outputs and is packaged in a
4mmx7mm 46 lead QFN. Individual lane LOS support is
included for module applications.

NOTES:
1. After channel loss, differential amplitudes at QLx411GRx inputs must meet the input voltage range specified in “Absolute
Maximum Ratings” on page 4.
2. Temperature = +25°C, VDD = 1.2V.
3. Output residual jitter is the difference between the total jitter at the lane extender output and the total jitter of the transmitted
signal (as measured at the input to the channel). Total jitter (TJ) is DJpp + 14.1 x RJRMS.
4. Measured using a PRBS 27-1 pattern. Deterministic jitter at the input to the lane extender is due to frequency-dependent,
media-induced loss only.
5. Rise and fall times measured using a 1GHz clock with a 20ps edge rate.
6. For active data mode, cable input amplitude is 300mVP-P (differential) or greater. For line silence mode, cable input amplitude
is 20mVP-P (differential) or less.
