Exar has added another device to its SONET/SDH product portfolio. The XRT95L34 (one-channel OC-12/STM-4 or four-channel OC-3/STM-1 framer) is a single chip solution for framing and processing SONET data. It has integrated OC-3/OC-12 clock and data recovery (CDR) and SERDES functionalities. It supports ATM mapping, and point-to-point protocol (PPP) for packet over SONET (POS). Application targets include edge and WAN ATM switches, IP routers and multiprotocol switches.
Distinguishing features are that it offers automatic protection switching (APS) - 1+1 and 1:n up to 1:14 - in a single chip, while competitive offerings need additional external devices to accomplish the same functionality. This offers customers protection and/or recovery of faulty data transmissions, ensuring smooth data processing and, when coupled with the device's integrated CDRs for both OC-12 and OC-3, accomplishes many key functions using less board space and at lower cost. In addition, the device conforms to 8/16 bit POS-PHY/UTOPIA Level 2 interface characteristics to process both POS and ATM traffic.
The XRT95L34 has four OC-3/STM-1 or one OC-12/STM-4 that interfaces to CDR and SERDES industry standard optical transceivers. It supports mapping for any standard combination of STS-12c/AU-4c or STS-3c/AU4. In addition, it provides four STS-3 telecom buses through a parallel interface or aggregates four low speed OC-3 devices on to a single OC-12 line.
The XRT95L34 in a 584-lead TBGA operates at 3,3 V with 5 V tolerant I/Os over the industrial temperature range.
