    LTE / WiFi Viterbi decoder

    Product code: TC1720

    TC1720 is a high throughput and low latency Viterbi decoder optimized for WiFi and LTE applications. It covers optionally also WCDMA specifications.

    Functional coverage:

    • 3GPP LTE
      • 64-states convolutional code with tail biting
      • 20 to 1024 bits payload with bit-granularity
      • Rate matching support
        • Inverse bit selection including LLR combining in case of repetition
        • Inverse bit collection
        • Sub-block deinterleaving
      • CRC check (CRC24A/CRC24B/CRC16B/CRC8B) with scrambling mask
    • WiFi
      • 64-states convolutional code with tail bits
      • 1 to 64536 bytes payload with byte-granularity
      • Code rates 1/2, 2/3, 3/4, 5/6
    • 3GPP-WCDMA
      • 256-states convolutional code with tail bits
      • 1 to 504 bits payload with bit-granularity
      • Code rate 1/2 and 1/3


    • Scalable throughput/area level, selectable prior Core synthesis (3 levels)
    • High throughput reachable(1-2 Gbps)
    • Very low latency
    • On-the-fly change of mode, block length, code rate and traceback length
    • Parameterized traceback length
    • No external memory required
    • Channel quality estimator
    • Low power Core
    • Silicon proven
    • ASIC Core: Verilog or VHDL RTL source code
    • FPGA Core available on all popular Altera, Lattice and Xilinx devices
