PM5344 SPTX

SONET/SDH PATH TERMINATING TRANSCEIVER

4 APPLICATION EXAMPLES

The following two examples show the SPTX used in typical SONET/SDH network

equipment applications. In the first example, the SPTX is paired with the PM5343

STXC 155 Mbit/s Section and Line overhead terminating transceiver to provide a

complete 155 Mbit/s SONET STS-3 or STS-3c/SDH STM-1 interface. In the

second example, four SPTX chips are used in conjunction with the PM5312

STTX 622 Mbit/s Section and Line overhead terminating transceiver to provide a

complete 622 Mbit/s SONET STS-12/SDH STM-4 interface. In both cases

external clock recovery and synthesis is available from a number of commercial

sources (additional information is available from PMC).
