Exar has released a next-generation silicon solution incorporating a line interface unit (LIU), jitter attenuator (JA) and ATM UNI framer in one innovative combination device. The XRT79L71, the first in a family of solutions, is a single-channel device targeted at telecom equipment including digital access and cross connect systems, wireless base stations, and digital subscriber line access multiplexers (DSLAMs), among others.
The device is a single-channel, asynchronous transfer mode (ATM), universal network interface (UNI) physical-layer processor incorporating a T3/E3 framer, LIU and JA. The device supports ATM direct mapping and cell delineation as well as PPP mapping and frame processing. For clear-channel framer applications it provides both transmission and reception of user data from the DS3/E3 payload. The device has a flexible microprocessor interface for easy configuration and control, and meets industry-standard UTOPIA II and POS-PHY specifications operating at 25, 33, or 55 Mhz.
The XRT79L71 has an integrated clock multiplier that generates DS3/E3 clocks from a single frequency clock source. It contains an on-chip 16-cell FIFO for ATM applications, which supports various configuration levels in both the transmit and receive directions. Also, the device has an on-chip 54-byte transmit and receive OAM cell buffer for the transmission, reception and processing of OAM cells. In addition, the XRT79L71 includes a PRBS generator/receiver. The device meets jitter specifications and is 3,3, 5 V input tolerant.
