Integrated PSK modem
  • Integrated PSK modem written in VHDL, including PSK modulation, demodulation, convolutional error correction encoding and decoding, V.35 scrambling, HDLC framing, TCP-IP network interface and USB 2.0 interface
  • Key features:
    • PSK (BPSK, QPSK, OQPSK) modulation
    • Continuous mode operation (i.e. Burst mode is not supported)
    • Convolution error correction, rates 1/2, 2/3, 3/4, 5/6 and 7/8
    • Serial HDLC to transmit empty frames over the synchronous link when no payload data is available
    • V.35 scrambling to randomize the modulated data stream
    • Maximum encoded data rate of 25 MSymbols/s when using a 100 MHz FPGA processing clock
    • Ancillary components are also included for streaming, test signal generation and bit error rate measurement
  • User interfaces:
    • Synchronous serial with elastic buffer or
    • TCP-IP server
    • USB 2.0 FS/HS
  • VHDL source code included.
  • Includes the following VHDL IP packages: COM-5401SOFT, COM5402SOFT, USB20SOFT, COM-1010SOFT, COM-1509SOFT and COM-1202SOFT (PSK modulation only)
  • Unlimited license to make and use. See the complete licensing terms at
