Name Dir Synchronous to
tx_std_coreclkin/
rx_std_coreclkin
Description
tx_std_pcfifo_full[-
1:0]
Output Yes TX phase compensation FIFO status full
flag.
tx_std_pcfifo_empty[-
1:0]
Output Yes TX phase compensation FIFO status
empty flag.
Byte Ordering
rx_std_byteorder_ena[-
1:0]
Input No Byte ordering enable. When this signal is
asserted, the byte ordering block initiates a
byte ordering operation if the Byte
ordering control mode is set to manual.
Once byte ordering has occurred, you
must deassert and reassert this signal to
perform another byte ordering operation.
This signal is an synchronous input signal;
however, it must be asserted for at least 1
cycle of
rx_std_clkout
.
rx_std_byteorder_flag[
-1:0]
Output Yes Byte ordering status flag. When asserted,
indicates that the byte ordering block has
performed a byte order operation. This
signal is asserted on the clock cycle in
which byte ordering occurred. This signal
is synchronous to the
rx_std_clkout
clock. You must a synchronizer this signal.
Byte Serializer and Deserializer
rx_std_byterev_ena[-
1:0]
Input No This control signal is available in when the
PMA width is 16 or 20 bits. When asserted,
enables byte reversal on the RX interface.
8B/10B
rx_std_polinv[-1:0] Input No Polarity inversion for the 8B/10B decoder,
When set, the RX channels invert the
polarity of the received data. You can use
this signal to correct the polarity of
differential pairs if the transmission
circuitry or board layout mistakenly
swapped the positive and negative signals.
The polarity inversion function operates
on the word aligner input.
