www.DataSheet4U.com NOVEMBER 2006 XRT94L43 SONET/SDH OC-12 TO 12XDS3/E3 MAPPER REV. 1.0.2 GENERAL DESCRIPTION The XRT94L43 is an SDH to PDH physical layer processor with integrated SONET OC-12 and 12 DS3/E3 framing controller. The XRT94L43 contains an integral SONET framer which provides framing and error accumulation in accordance with ANSI/ITUT specifications. For a multiple channel DS3/E3 feature, each channel contains identical elements. The configuration of this device is through internal registers accessible via an 8-bit parallel, memory mapped, microprocessor interface. The SONET/SDH transmit and receive blocks are used to transmit/receive an STS-12/STM-4 signals or compose and decompose 12, STS-1/DS3/E3 signals. The blocks operate at a peak internal clock speed of 77 MHz and support 8-bit internal data paths. The transmit and receive blocks are compliant with both SONET and SDH standards. The XRT94L43 performs all SONET transport and path overhead processing for use in broadband data transport applications.
