8.3.1.3.2 Data Generator

Data generator can be programmed to generate either user defined MAC packets or PRBS stream.

Following parameters of generated MAC packets can be configured (refer to registers<0x061B>,register<0x061A> and register<0x0624> for required configuration):

  • Packet Length
  • Inter-packet gap
  • Defined number of packets to be sent or continuous transmission
  • Packet data-type: Incremental/Fixed/PRBS
  • Number of valid bytes per packet
