Channel Interface
The following signals are used in 8-bit 8B/10B modes:
rx_dataoutfull[7:0]: 8-bit decoded data (rx_dataout)
rx_dataoutfull[8]: Control bit (rx_ctrldetect)
rx_dataoutfull[9]: Code violation status signal. It indicates error
detected in rx_dataoutfull[7:0], which is replaced by invalid
code-group (invalid or running disp.error) in GIGE mode. In PCI
Express, when code violation occurs, the EDB character is placed on the
erroneous data byte (= K30.7) (rx_errdetect)
rx_dataoutfull[10]: rx_syncstatus
rx_dataoutfull[11]: Disparity error status signal. It indicates
disparity error detected in rx_dataoutfull[7:0]
(rx_disperr)
rx_dataoutfull[12]: Pattern detect status signal
(rx_patterndetect)
rx_dataoutfull[13]: Rate Match FIFO deletion status indicator
(rx_rmfifodatadeleted) in non-PIPE/PCIe modes.
rx_dataoutfull[14]: Rate Match FIFO insertion status indicator
(rx_rmfifodatainserted) in non-PIPE/PCIe modes.
rx_dataoutfull[14:13]: PIPE/PCI-E mode: 2'b00: data OK;
2'b01: 1 SKP deletion; 2'b10: elastic buffer underflow if data is 0xFE,
else 1 SKP insertion; 2b11: elastic buffer overflow (rx_pipestatus)
rx_dataoutfull[15]: 8B/10B running disparity indicator
(rx_runningdisp)
10-bit Core
fabric-Transceiver
Channel Interface
The following signals are used in 8-bit SONET/SDH mode:
rx_dataoutfull[7:0]: 8-bit un-encoded data (rx_dataout)
rx_dataoutfull[8]: rx_a1a2sizeout
rx_dataoutfull[10]: rx_syncstatus
rx_dataoutfull[11]: Reserved
rx_dataoutfull[12]: rx_patterndetect
rx_dataoutfull[9:0]: 10-bit un-encoded data (rx_dataout)
rx_dataoutfull[10]: rx_syncstatus
rx_dataoutfull[11]: 8B/10B disparity error indicator
(rx_disperr)
rx_dataoutfull[12]: rx_patterndetect
rx_dataoutfull[13]: Rate Match FIFO deletion status indicator
(rx_rmfifodatadeleted) in non PIPE/PCIe modes
rx_dataoutfull[14]: Rate Match FIFO insertion status indicator
(rx_rmfifodatainserted) in non PIPE/PCIe modes
rx_dataoutfull[15]: 8B/10B running disparity indicator
(rx_runningdisp)
