Description
The QT1010 is a fully integrated
bidirectional clock and data recovery device
for optical LAN/WAN/MAN/SAN Ethernet,
Fibre Channel and SONET applications
deploying XFP modules.
The QT1010 provides the interface between
a 10Gb/s1 SerDes and the optical sub-
assemblies in an XFP module.

In the transmit direction, the QT1010
compensates for loss and distortion caused
by the electrical XFI interface from the host
SerDes. In the more sensitive receive
direction, the QT1010 performs clock and
data recovery and regeneration of the signal
from the receive optical subassembly.
The retimed signal is provided to the host
SerDes.
