5.6.2.3Receiver 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.

5.6.2.4Selective Power-Down

The IXF1104 offers the ability to selectively power-down any of the SerDes TX or RX ports that are not being used. This is done via “TX and RX Power-Down ($0x787)” on page 219.

5.6.2.5Receiver Jitter Tolerance

The SerDes receiver architecture is designed to track frequency mismatch, recover phase, and is tolerant of low-frequency data jitter. Figure 23 specifies the SerDes core receiver sinusoidal jitter tracking capabilities.
