AHA4702E
DVB-S2 Compliant LDPC/BCH Forward Error Correction (FEC) Encoder Core
 
The AHA4702E FEC encoder core is fully compliant with section 5.3 of the Digital Video Broadcast S2 (DVB-S2) standard.  It is capable of 200 Mbit/sec user data rate with a 2/3 rate LDPC Code in an ASIC.  The core supports all codes, frame sizes, and interleave schemes set forth in the DVBS2 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).
 
Features
  • DVB-S2 compliant
  • LDPC inner code with a BCH outer code
  • Supported codes: 1/4 through 9/10 rates
  • Supported block sizes: 16K and 64K
  • Packet Error Rate performance to 10E-7
  • Full ACM and VCM compliance
