PRBS23

PRBS23 refers to a specific type of Pseudo-Random Binary Sequence (PRBS) with a polynomial of degree 23. PRBS sequences are widely used in telecommunications and digital systems for testing purposes. They generate a seemingly random stream of bits that possesses predictable statistical properties, making them ideal for simulating real-world data patterns. The "23" in PRBS23 indicates that the sequence is generated by a feedback shift register of length 23. The output sequence repeats after 2^23 - 1 bits, which is a very large number (8,388,607 bits). This long period makes it suitable for testing high-speed data links and complex systems where a long, stable test pattern is required. PRBS23 is commonly employed in applications like Ethernet testing, SONET/SDH testing, and general digital signal integrity analysis. Its predictable nature allows for easy error detection by comparing the transmitted sequence with the received sequence. Any discrepancies indicate signal degradation or errors within the system under test. The specific polynomial used to generate PRBS23 can vary, but common ones are well-defined and standardized by various industry bodies.
