Description
indicates symbol lock and valid data on
RX_DATA and RX_DATAK
used to communicate completion of several PHY
functions including power management state
transitions and receiver detection
indicates receiver detection of an electrical idle;
this is an asynchronous signal
encodes receiver status and error codes for the
received data stream and receiver detection (see
Table
Description
source synchronous 250 MHz transmit clock
input from MAC. All input data and signals to the
PHY are synchronized to this clock.
source synchronous 250 MHz clock output for
received data and status signals bound for the
MAC.
100 MHz reference clock input. This is the
spread spectrum source clock for PCI Express.
Differential pair input with 50
termination.
input or output to create a compensation signal
internally that will adjust the I/O pads
characteristics as PVT drifts. Connect to V
through a 49.9
reference voltage input for SSTL_2 class I
signaling. Connect to 1.25 V.
