A single chip regenerator for transmission systems operating in the range 2-320 Mbits/s

Circuit and operational details of a single chip regenerator, developed by BTRL, are presented. The device is capable of operation over the entire span of currently agreed CCITT hierarchical transmission levels from 2 Mbit/s to 140 Mbits/s. Extension to 280 Mbits/s (320 MBd when coded by 7B8B for optical system applications) is also demonstrated to be possible.
