Chapter 1: Transceiver Architecture in Stratix IV Devices
Transceiver Block Architecture
February 2011 Altera Corporation
By default, the Stratix IV GX and GT receiver assumes a LSB-to-MSB transmission. If
the transmission order is MSB-to-LSB, the receiver forwards the bit-flipped version of
the parallel data to the FPGA fabric on the rx_dataout port. The receiver bit reversal
feature is available to correct this situation.
The receiver bit reversal feature is available through the rx_revbitordwa port only in
Basic single-width and double-width modes with the word aligner configured in
bit-slip mode. When the rx_revbitordwa signal is driven high in Basic single-width
mode, the 8-bit or 10-bit data D[7:0] or D[9:0] at the output of the word aligner gets
rewired to D[0:7] or D[0:9], respectively. When the rx_revbitordwa signal is driven
high in Basic double-width mode, the 16-bit or 20-bit data D[15:0] or D[19:0] at the
output of the word aligner gets rewired to D[0:15] or D[0:19], respectively.
Flipping the parallel data using this feature allows the receiver to forward the correct
bit-ordered data to the FPGA fabric on the rx_dataout port in the case of MSB-to-LSB
transmission.
