AHA4540EVB

The AHA4540-EVB is an evaluation board that can be integrated into a communications system for evaluation of the AHA4540 Turbo Product Code (TPC) encoder/decoder device at real system speeds.  Alternatively, it can be connected to a Bit Error Rate Tester (BERT) for evaluating the performance of the AHA4540 with a user supplied communications channel.

Features

• 148 MHz maximum clock input (S_UCLK, S_CCLK)
• 148 Mbits/sec maximum serial data rate
• Simultaneous independent TPC encoding and decoding
• Access to registers in the AHA4540 device
• Up to 4 bit soft decision input to TPC decoder
• On-board synchronization in the AHA4540
• On-board AHA4540 includes CRC insertion and detection
• SMA connectors for all clock and data signals on/off board
• 2 frequency synthesizers on board generate payload side clocks at frequencies up to 60 MHz
• User can supply payload and channel side bit clocks up to 148 MHz max frequency
• RS-232 control interface for board configuration and monitoring
