Bit-Error Rate (BER) for high speed serial data communication

Last Updated:

Today's serial data communication data rates continue to increase, due to bandwidth-hungry applications that include video transport, data over IP, wireless base-station, and medical applications. While data rates are driven upwards, latency requirements are still tight, specifically for full duplex communication that involves streaming data like voice. Lower latency means less room for error correction, which in turn puts more stringent requirements on the number of acceptable bit-errors in serial transmission. For example, the upcoming wireless base-station networking standard, Open Base Station Architecture Initiative (OBSAI) requires a BER of better than 10-15.
