6.1. Transceiver to IP Parallel Data Interface Width
DP 8B/10B Channel Coding has a native symbol size of 10-bits. This value multiplied by the SYMBOLS_PER_CLOCK parameter determines the size of the IP parallel data interface from the Transceiver (XCVR). Therefore, the DP1.4 datapath in the IP, configured with QUAD SYMBOLS_PER_CLOCK, has a 40-bit wide parallel data interface from the transceiver.
DP 128B/132B Channel Coding has a native 32- or 64-bit symbol size, which is multiplied by 2 depending on link rates. Therefore, the DP2.0 datapath in the IP has a 32/64-bit wide parallel data interface from the transceiver.
Given that DP2.0 is backward compatible with DP1.4 and that selecting UHBR10 link rates requires all link rates below that to be supported (RBR, HBR, HBR2, HBR3), the external IP interface is maintained at 40-bit wide, while internally the IP muxes the input between the 40-bit wide DP1.4 datapath and 32/64-bit wide DP2.0 datapath.
- FEC decoding where symbol errors are detected and corrected.
- Descrambling.
- Intra_Lane Super Shifting Deshifting to reverse the Super Symbol Shifting done on the transmit side.
- Lane Converter to convert from 1 or 2 physical lanes to fixed 4 logical lanes.
- LLCP demuxer locks onto the LLCP marker sequence.
- MTP demuxer where streams symbols are extracted accroding to the VC Payload table.
- LL decoder (one per-stream) where the stream symbols are decoded into:
- Video stream
- LPCM Audio stream
- Secondary data stream
You configure the sink to output the video data as a proprietary data stream. You specify the output pixel data width at 6, 8, 10, 12, or 16 bpc. This format can interface with downstream Video and Image Processing (VIP) Suite components.
The AUX controller can operate in an autonomous mode in which the sink controls all AUX channel activity without an external embedded controller. The IP outputs an AUX debugging stream so that you can inspect the activity on the AUX channel in real time.
