June 23, 2016 Quad Lane Extender
The QLX4600-S30 is a settable quad receive-side equalizer
with extended functionality for advanced protocols operating
with line rates up to 6.25Gb/s such as DisplayPort v1.2
(HBR1/2), InfiniBand (SDR and DDR), PCI Express and
10GBase-CX4. The QLX4600-S30 compensates for the
frequency dependent attenuation of copper twin-axial cables,
extending the signal reach up to 30m on a 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-S30 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-S30
enables per channel throughputs of up to 6.25Gb/s while …
