transceiver block
receiver PLL to lock
the received data. Input port [NUMBER_OF_CHANNELS -
1..0] wide. The
rx_locktodata[] port
can overwrite the rx_locktorefclk[]
port.
tx_in[] Yes Transceiver block
transmitter channel
data input port. Input port [CHANNEL_WIDTH *
NUMBER_OF_CHANNELS - 1..0] wide. If
you set the
USE_8B_10B_MODE
parameter to OFF and the
USE_DOUBLE_DATA_MODE parameter is
set to OFF , the deserialization factor is
CHANNEL_WIDTH .
If you set the USE_8B_10B_MODE
parameter to OFF and the
USE_DOUBLE_DATA_MODE parameter is
set to ON , the deserialization factor is
CHANNEL_WIDTH / 2.
If you set the USE_8B_10B_MODE
parameter to ON , the deserialization factor
is 10.
tx_ctrlenable[] No Control character
enable. Enables the
8B/10B encoder to
identify control
characters. Labels
an input character
as a control code. Input port [NUMBER_OF_CHANNELS *
DWIDTH_FACTOR - 1..0] wide. If
tx_ctrlenable[] port is high, the sent
word is a control character.
tx_srlpbk[] No Reverse serial
loopback input.
