8.3.5 Pseudo-Random Bit Stream (PRBS) Generator

The TLK2711-SP has a built-in 27 – 1 PRBS function. When the PRBSEN pin is forced high, the PRBS test is enabled. A PRBS is generated and fed into the 10-bit parallel-to-serial converter input register. Data from the normal input source is ignored during the PRBS mode. The PRBS pattern is then fed through the transmit circuitry as if it were normal data and sent out to the transmitter. The output can be sent to a bit error rate tester (BERT), the receiver of another TLK2711-SP, or looped back to the receive input. Because the PRBS is not really random, but a predetermined sequence of 1s and 0s, the data can be captured and checked for errors by a BERT.
