PRODUCTION DATA.
It is possible to calculate the approximate Bit Error Rate (BER). The following is required:
The BER is less than or equal to one over the product of 24 times the PCLK rate times the test duration. If we assume a 65-MHz PCLK, a 10 minute (600 seconds) test, and a PASS, the BERT is ≤ 1.07 × 10E-12.
The BIST mode runs a check on the data payload bits. The LOCK pin also provides a link status. It the recovery of the C0 and C1 bits does not reconstruct the expected clock signal, the LOCK pin will switch Low. The combination of the LOCK and At-Speed BIST PASS pin provides a powerful tool for system evaluation and performance monitoring.
