rx_locktodata
(control signal
for Receiver PLL to lock to the
received data)
Set this signal in manual lock mode to force the receiver PLL to lock to the
serial data stream.
For more information about this option, refer to the Stratix GX Analog
Description chapter in volume 2 of the Stratix GX Device Handbook.
rx_clkout
(receiver input clock)
The rx_clkout signal is a recovered clock output from individual
receiver channels. One rx_clkout signal is available per channel.
rx_locked
(indicates that the
Receiver PLL is locked to the
reference clock (active low))
The rx_locked signal is an active low signal that indicates that the
receiver PLL is phase locked to the reference clock. In data mode, this
signal might be deasserted because the phase is being locked to the data
and not the reference clock.
rx_freqlocked
(indicates that
the Receiver PLL is locked to the
input data)
Refer to the Ports & Parameters chapter in volume 2 of the Stratix GX
Device Handbook.
rx_signaldetect
(indicates
receiver signal is detected with data)
Refer to the Ports & Parameters chapter in volume 2 of the Stratix GX
Device Handbook.
rx_syncstatus
(output signal
from pattern detector and word
aligner)
The rx_syncstatus signal indicates the status of the word aligner.
rx_patterndetect
(indicates
pattern has been detected)
The rx_patterndetect signal is an active high signal that signifies
that the comma appears in the current byte boundary of the incoming data
stream.
rx_ctrldetect
(indicates
8B/10B decoder detected a control
code)
Refer to the Ports & Parameters chapter in volume 2 of the Stratix GX
Device Handbook.
rx_errdetect
(indicates 8B/10B
decoder detected an error code
Refer to the Ports & Parameters chapter in volume 2 of the Stratix GX
Device Handbook.
rx_disperr
(indicates 8B/10B
decoder detected disparity error)
Refer to the Ports & Parameters chapter in volume 2 of the Stratix GX
Device Handbook.
rx_a1a2sizeout
(a1a2size
signal synchronized to the clock of
the word aligner)
Refer to the Ports & Parameters chapter in volume 2 of the Stratix GX
Device Handbook.
rx_fifoalmostempty
(high
when rate matching FIFO is in
almost empty condition)
If Generic FIFO is enabled to perform rate matching between the
recovered clock and local receiver clock, this signal indicates an almost
empty condition when driven HIGH.
rx_fifoalmostfull
(high when
rate matching FIFO is in almost full
condition)
If Generic FIFO is enabled to perform rate matching between the
recovered clock and local receiver clock, this signal indicates an almost
full condition when driven HIGH.
rx_bisterr
(error status for
built-in self-test)
Refer to the Ports & Parameters chapter in volume 2 of the Stratix GX
Device Handbook.
rx_bistdone
(self-test complete
signal)
Refer to the Ports & Parameters chapter in volume 2 of the Stratix GX
Device Handbook.
