buffer when the RXCHANBONDMASTER, RXCHANBONDSLAVE, or
RXCHANBONDLEVEL change.
After a PRBS Error
PRBSCNTRESET is asserted to reset the PRBS error counter.
After Comma Realignment

elastic buffer during comma realignment.
Power Down
Functional Description
The GTP transceiver supports a range of power-down modes. These modes support both generic
power management capabilities as well as those defined in the PCI Express® and SATA standards.
The GTP transceiver offers different levels of power control. Each channel in each direction can be
powered down separately using TXPD and RXPD. The PLL0PD port directly affects the PLL0
while the PLL1PD port affects PLL1.
Ports and Attributes
Table 2-23 defines the power-down ports.

PLL1PD In Async This active-High signal powers
down PLL1.
RXPD[1:0] In Async Powers down the RX lane
according to the PCI Express
PIPE protocol encoding.
