sonet/sdh framer

The PM5342 spectra-155 sonet/sdh framer is a single-chip solution for OC-3 clock recovery, synthesis, framing, and mapping. The device incorporates a sonet/sdh payload mapper/extractor and Packet-Over-sonet interface. The line interface module provides high-speed 155-Mbit/sec pseudo-ecl outputs that directly interface to optical modules. The clock synthesis unit generates an sts-3/sts-3c or sts-1 clock from a 19.44-MH¥reference signal.
