    The PM5345 SUNI chip maps ATM cells from an ATM switch core or an adaptation layer processor into the SONET payload, adds SONET-based framing and overhead according to ANSI and CCITT recommendations and the ATM Forum UNI specification. The device contains on-chip serial-to- parallel conversion operating at 155 MHz, and utilizes pseudo-ECL inputs and outputs for the high speed signals. This allows the SUNI to directly interface with commercially available optical modules and clock recovery circuits and to twisted pair interface circuitsfor operation over category-5 unshielded twisted pair wiring (UTP-5). The system side interface of the SUNI can operate in either 8-bit or 16-bit mode, up to 25 MHz. On chip overhead expansion logic allows access to all of the SONET overhead bytes so that external logic c an expand the function to a full Network-Node Interface (NNI) c ompliant SONET-ATMfunction for use in public network applications.
