The serializer converts the low-speed parallel 8-bit or 10-bit data from the transmitter
PCS to high-speed serial data for the transmitter output buffer. The serializer operates
with a high-speed clock at half of the serial data rate. The serializer transmission
sequence is LSB to MSB.
Input bit-flip—reverses the bit order at a byte level at the input of the transmitter
phase compensation FIFO. For example, if the 16-bit parallel transmitter data at
the tx_datain port is '10111100 10101101' (16'hBCAD), selecting this option
reverses the input data to the transmitter phase compensation FIFO to '00111101
10110101' (16'h3DB5).
Bit-slip control—delays the data transmission by a number of specified bits to the
serializer with the tx_bitslipboundaryselect port. For usage details, refer to
the
TX bit reversal option enabled in
the ALTGX MegaWizard
