When asserted high—all digital and analog
circuitry within the PCS, PMA, CMU channels, and
the CCU of the transceiver block, is powered down.
Asserting the gxb_powerdown signal does not
power down the REFCLK buffers.
When asserted high—the receiver PCS blocks are
reset. Refer to
Functionally equivalent to the rxvalid signal
defined in the PCIe specification revision 2.0.
Functionally equivalent to the rxelecidle
signal defined in the PCIe specification revision
2.0.
If the electrical idle inference block is enabled—
it drives this signal high when it infers an
electrical idle condition, as described in
“Electrical Idle Inference” on page
Otherwise, it drives this signal low.
If the electrical idle inference block is disabled—
the rx_signaldetect signal from the signal
detect circuitry in the receiver buffer is inverted
and driven on this port.
