SPECTRA™-155

SONET/SDH Payload Extractor/Aligner

• Maps three DS3 bit streams into a

STS-3 (STM-1/AU3) frame.

• Available in a 256-pin, Super Ball Grid

Array (SBGA) package.

• Supports industrial temperature range

(-40°C to 85°C) operation.

FEATURES

• Monolithic, SONET/SDH Payload

• Maps three serial data streams (e.g.,

Extractor/Aligner for use in STS-1

Frame Relay, PPP, or Ethernet
