CMMB LDPC decoder Product code: TC4300

TC4300 is a LDPC decoder designed for China Multimedia Mobile Broadcasting (CMMB) specifications. The Core is a stand-alone module, with no external memory needs. It is available for mainstream FPGA or ASIC device targets. Two throughput levels are proposed:

• low-complexity Core: 75 Mbps
• high-throughput Core: 150 Mbps

Features:

• Compliant with China Multimedia Mobile Broadcasting (CMMB) specifications
• Block size 9216 bits
• Code rate 1/2 and 3/4
• Near floating point error correction performance
• Early iteration stopping feature
• Patented architecture allowing high throughput for reduced footprint
• On-the-fly change of code rate and number of iterations
• Low latency
• Single FPGA Core (no external memory required), available on all popular Xilinx, Altera and Lattice devices
• ASIC Core: Verilog or VHDL RTL Core delivery
