Application NoteAnalog
PRBS Mode Setup for the MAX9257/MAX9258 Evaluation Kit
Guide for using the internal bit error-rate testing (BERT) and PRBS mode on the MAX9257/MAX9258 SerDes evaluation kit to verify link functionality and signal quality.
Overview
This application note describes how to configure the internal bit error-rate testing (BERT) feature of the MAX9257/MAX9258 SerDes chipset using pseudo-random bit sequence (PRBS) mode. It provides a step-by-step procedure for setting up the MAX9257/MAX9258 evaluation kit, including software installation, register configuration for 10-bit and 12-bit patterns, and cable connections. The document includes eye diagram examples and test results for 0.5m and 2m shielded JAE cables at 30MHz transmit clock rates, demonstrating how to log bit errors and verify link integrity without requiring external test equipment.
Use Cases
- High-speed data link verification
- Automotive ECU signal integrity testing
- SerDes cable performance evaluation
- Bit error rate analysis
- System-level communication troubleshooting
