MaxLinear, Inc. Interface - Interface - Telecom - XRT86SH328IB XRT86SH328IB

The XRT86SH328IB is an integrated VT/TU Mapper designed for telecom applications, featuring 28 port T1 or 21 port E1 Line Interface Units. It includes built-in DS1/E1/J1 Framers for performance monitoring and processes Section, Line, and Path overhead in SONET/SDH data streams. The device supports the mapping of up to 28 T1 streams or 21 E1 streams into a serial DS3, compliant with ITU-T G.747 standards. The XRT86SH328IB incorporates internal De-Synchronizer circuits that eliminate jitter from T1 or E1 signals without requiring external clock references. It allows flexible insertion of Transport Overhead (TOH) and Path Overhead (POH) bytes through hardware and software control. Each channel includes a PRBS Pattern Generator and Receiver for measuring bit-error performance, and the device supports various mapping configurations, including mixed mapping of tributaries. Operating with a low power supply of 1.8V for core logic and 3.3V for I/O, the XRT86SH328IB is suitable for channelized and unchannelized DS3 applications, T1/E1 terminals, and SONET/SDH Add-Drop Multiplexers (ADMs). The product is housed in a 568 Ball BGA package and operates within a temperature range of -40¬8C to +85¬8C.
