The word aligner and rate matcher operations and patterns are pre-configured for
PCIe, GIGE, and XAUI modes, and cannot be altered.
Enabling this option sets the word aligner in Manual
Alignment mode. In Manual Alignment mode, the
word aligner operation is controlled by the input signal
rx_enapatternalign.
Two options are available in manual mode:
■
■
This option sets the word aligner in Bit-Slip mode.
Enabling this option creates an input signal
rx_bitslip to control the word aligner. At every
rising edge of the rx_bitslip signal, the bit slip
circuitry slips one bit into the received data stream,
effectively shifting the word boundary by one bit.
SDI
Because word alignment and framing occur after
de-scrambling, the word aligner in the receiver data
path is not useful in SDI systems. Altera recommends
driving the ALTGX rx_bitslip signal low to prevent
the word aligner from inserting bits in the received
data stream.
This option sets the word aligner in Automatic
Synchronization State Machine mode. This mode is
available only in Single-width mode for 8B/10B
encoded data:
■
or
■
Realign continuously while the
rx_enapatternalign signal is high.
Realign at the rising edge of the
rx_enapatternalign signal.
