Table 75.  Word Aligner and Bitslip
Name Direction Clock Domain Description
tx_std_bitslipboundarysel[5 <n>-1:0] Input

Asynchronous

SSR17

Bitslip boundary selection signal. Specifies the number of bits that the TX bit slipper must slip.

rx_std_bitslipboundarysel[5 <n>-1:0] Output

Synchronous to

rx_clkout

This port is used in deterministic latency word aligner mode. It reports the number of bits that the RX block slipped to achieve deterministic latency.

rx_std_wa_patternalign[<n>-1:0] Input

Asynchronous

SSR17

This port is enabled when you place the word aligner in manual mode. In manual mode, you align words by asserting rx_std_wa_patternalign. When the PCS-PMA Interface width is 10 bits, rx_std_wa_patternalign is level sensitive. For all the other PCS-PMA Interface widths, rx_std_wa_patternalign is positive edge sensitive.

You can use this port only when the word aligner is configured in manual or deterministic latency mode.

When the word aligner is in manual mode, and the PCS-PMA interface width is 10 bits, this is a level sensitive signal. In this case, the word aligner monitors the input data for the word alignment pattern, and updates the word boundary when it finds the alignment pattern.

For all other PCS-PMA interface widths, this signal is edge sensitive.This signal is internally synchronized inside the PCS using the PCS parallel clock and should be asserted for at least 2 clock cycles to allow synchronization.

rx_std_wa_a1a2size[<n>-1:0] Input

Asynchronous

SSR17

Used for the SONET protocol. Assert when the A1 and A2 framing bytes must be detected. A1 and A2 are SONET framing alignment overhead bytes and are only used when the PMA data width is 8 or 16 bits.

The 2 alignment markers valid status is captured in the 2 bit of rx_std_wa_ala2size signal. When both the markers are matched, then the value of the signal is 2'b11.

If simplified data interface is disabled, rx_rmfifostatus is a part of rx_parallel_data. For most configurations, rx_rmfifostatus corresponds to rx_parallel_data[14:13]. Refer to section Transceiver PHY PCS-to-Core Interface Reference Port Mapping to identify the port mappings to rx_parallel_data for your specific transceiver configurations.

rx_bitslip[<n>-1:0] Input

Asynchronous

SSR17

Used when word aligner mode is bitslip mode. When the Word Aligner is in either Manual (FPGA Fabric width controlled), Synchronous State Machine or Deterministic Latency ,the rx_bitslip signal is not valid and should be tied to 0. For every rising edge of the rx_std_bitslip signal, the word boundary is shifted by 1 bit. Each bitslip removes the earliest received bit from the received data.

rx_std_bitrev_ena[<n>-1:0]

Input

Asynchronous

SSR17

When asserted, enables bit reversal on the RX interface. Bit order may be reversed if external transmission circuitry transmits the most significant bit first. When enabled, the receiver receives all words in the reverse order. The bit reversal circuitry operates on the output of the word aligner.

tx_polinv[<n>-1:0]

Input

Asynchronous

SSR17

When asserted, the TX polarity bit is inverted. Only active when TX bit polarity inversion is enabled.

rx_polinv[<n>-1:0]

Input

Asynchronous

SSR17

When asserted, the RX polarity bit is inverted. Only active when RX bit polarity inversion is enabled.
