PM5312 STTX

SONET/SDH TRANSPORT TERMINATING TRANSCEIVER

4 APPLICATION EXAMPLES

The following two diagrams shown the STTX used in an ATM application as an

STS-3c/STM-1 to STS-12/STM-4 multiplexer using four PM5345 SUNI-155 ATM

interface chips, and in an add-drop multiplexer application using four PM5344

SPTX path termination chips instead of the SUNI-155 chips to achieve access to

circuit-switched bandwidth. Serial to Parallel / Parallel to Serial conversion, clock

recovery and clock synthesis is available from a number of commercial sources.
