AHA4702DHS-SB
The AHA4702DHS-SB FEC decoder core is compliant with section 5.3 of the Digital Video Broadcast S2 (DVB-S2) standard for short frame blocks (16K). It is capable of 600 Mbit/sec user data rate with a 2/3 rate LDPC Code and 25 iterations in an Altera Stratix IV FPGA. The core supports all codes and symbol interleave schemes for short frame blocks specified in the DVB-S2 specification for broadcast, interactive, digital satellite news gathering, and professional services. The core allows code and modulation changes on a block-by-block basis to fully support both Adaptive Coding and Modulation (ACM) and Variable Coding and Modulation (VCM).
