rx_locktodata
(control signal
for Receiver PLL to lock to the
received data)
Refer to the Ports & Parameters 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))
Transmitter PLL and receiver PLL lock indicator.
For pll_locked, High = transmitter PLL is locked to the reference
clock.
For rx_locked, Low = receiver PLL is locked to 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)
Indicates when the word aligner has aligned to the byte boundary. The
rx_syncstatus
signal goes high for one rx_clkout period when the
word aligner aligns to the new byte boundary. In 16-bit mode, each high
and low byte has a separate rx_syncstatus signal.
rx_patterndetect
(indicates
pattern has been detected)
Similar to rx_syncstatus, except that rx_patterndetect asserts
only when the word alignment pattern appears in the data stream within
the synchronized byte boundary.
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)
A loopback of the rx_a1a2size signal that is synchronized with the
current byte from the word aligner.
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.
