    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


    • 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
