Receiver Operational Overview
The receiver structure performs Clock and Data Recovery (CDR) on the incoming serial
data stream. The quality of this operation is a dominant factor for the Bit Error Rate (BER)
system performance. Feed forward and feedback controls are combined in one receiver
architecture for enhanced performance. The data is over-sampled and a digital circuit
detects the edge position in the data stream. A signal is not generated if an edge is not
found. A feedback loop takes care of low-frequency jitter phenomenon of unlimited
amplitude, while a feed forward section suppresses high-frequency jitter having limited
amplitude. The static edge position is held at a constant position in the over-sampled by a
constant adjustment of the sampling phases with the early and late signals.
Selective Power-Down
The IXF1104 MAC offers the ability to selectively power-down any of the SerDes TX or RX
ports that are not being used. This is done via

Receiver Jitter Tolerance
The SerDes receiver architecture is designed to track frequency mismatch, recover phase,
and is tolerant of low-frequency data jitter.
