Dvb-s2x demodulator IP

Supports CCM, ACM and VCM
Supports roll-off factors 5%, 10%, 15%, 20%, 25% to 35%
Support for short and normal blocks (16,200 bits and 64,800 bits) with pilots only

This is single demodulator subsystem compliant DVB-S/S2/S2X satellite standards.
It is meant to be integrated in the L2A/L2B SOCs. The single demodulator subsystem is made of several blocks.
1 narrow-band demodulator DVB-S / DVBS2 / DVB-S2X up to 65 Msymb/s.
1 DVB-S FEC (Viterbi, Reed-Solomon, Super FEC)

Multiplexed LDPC/BCH decoder: The DVB-S2 FEC block can simultaneously decode 8 independent input streams. Each input stream has its own input connection. However, the cell only includes one LDPC decoder and one BCH decoder. Thus, the 8 input streams are stored in 8 independent buffers. When a frame is ready, it is processed in the LDPC decoder, then in the BCHdecoder and finally output to the appropriate transport stream.
LDPC decoder: The LDPC decoder can decode normal and short frames and all DVB-S2 and S2X Broadcast and Interactive profiles, but not VLSNR.
BCH Decoder: The BCH decoder is able to correct up to 12bits for Code rates where more than 192 redundancy bits are available. As such, correction is only possible up to 10bits for 2/3 and 5/6 code rates, and only up to 8bits for 8/9 and 9/10 code rates.
Packet Delinter: The packet delineator is used for descrambling, checking the integrity of BBFrame headers, processing the cache and data fields and providing a lock indicator
