XRT94L31 - 3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER

Datasheet Summary

Description

The XRT94L31 is a highly integrated SONET/SDH terminator designed for E3/DS3/STS-1 mapping/demapping functions from either the STS-3 or STM-1 data stream.

The XRT94L31 interfaces directly to the optical transceiver.

Features

  • Provides DS3/ E3 mapping/de-mapping for up to 3 tributaries through SONET STS-1 or SDH AU-3 and/or TUG-3/AU-4 containers.
  • Generates and terminates SONET/SDH section, line and path layers.
  • Integrated SERDES with Clock Recovery Circuit.
  • Provides SONET frame scrambling and descrambling.
  • Integrated Clock Synthesizer that generates 155 MHz and 77.76 MHz clock from an external 12.96/ 19.44/77.76 MHz reference clock.
  • Integrated 3 E3/DS3/STS-1.

The XRT94L31 interfaces directly to the optical transceiver. The XRT94L31 processes the section, line and path overhead in the SONET/SDH data stream. The processing of path overhead bytes within the STS-1s or TUG-3s includes 64 bytes for storing the J1 bytes. Path overhead bytes can be accessed through the microprocessor interface or via serial interface.
