Description

The XRT83SL34 is a fully integrated Quad (four channel) short-haul line interface unit for T1
(1.544Mbps) 100W, E1 (2.048Mbps) 75W or 120W, or J1 110W applications. In T1 applications, the XRT83SL34 can generate five transmit pulse shapes to meet the short-haul Digital Cross-Connect (DSX-1) template requirements. It also provides programmable transmit pulse generators for each channel that can be used for output pulse shaping allowing performance improvement over a wide variety of conditions.

The XRT83SL34 provides both a parallel Host microprocessor interface as well as a Hardware mode for programming and control. Both the B8ZS and HDB3 encoding and decoding functions are selectable as well as AMI. An on-chip crystal-less jitter attenuator with a 32 or 64 bit FIFO can be placed either in the receive or the transmit path with loop bandwidths of less than 3Hz.

The XRT83SL34 provides a variety of loop-back and diagnostic features as well as transmit driver short circuit detection and receive loss of signal monitoring. It supports internal impedance matching for 75W 100W, 110W and 120W for both transmitter and receiver. In the absence of the power supply, the transmit outputs and receive inputs are tri-stated allowing for redundancy applications The chip includes an integrated programmable clock multiplier that can synthesize T1 or E1 master clocks from a variety of external clock sources.



Description

Joining Exar's proven and extensive T1/E1 XRT83SL34 device family, the company adds hree new products. A single-channel XRT83SL30, a quad (four-channel) XRT83SL34, and octal (eight-channel) XRT83SL38. These devices are ideal for the high andwidth needs from the backbone or Core to the Metro Area Network. OEM roducts for this technology include Multi-Service Provisioning Platforms (MSPP), access devices, media gateways, routers frame relay access devices, and ireless base stations.

What is R3 TechnologyTM?

Exar's R3 TechnologyTM Reconfigurable, Relayless Redundancy) delivers key innovative features to customers designing T1/E1/J1 interface cards. The  XRT83SL34 devices are Reconfigurable -- integrated termination supporting all common T1/E1/J1 line impedances (75-120 ohms) enabling customers to build boards with a single bill-of-materials. Exar's on-board reconfigurable clock synthesizer allows manufacturers to build hardware in advance and configure the product (in software) for the particular application or market at the time of shipment. Conventional approaches require fixed settings - T1, or E1, or J1, forcing customers to determine device settings before manufacturing, and carry all configurations in inventory even if they are not immediately required. Also, the series employs Relayless Redundancy eliminating the need for external relays for 1:1 and 1+1 applications by establishing a back-up channel that is brought on-line in event of failure.

Product Highlights

The XRT83SL34 devices support all international (North America, Europe, or Japan) line impedances at 75, 100, 110, and 120-ohms. The XRT83SL8X series has a frequency synthesizer that can take a number of different clocks and generate either a 1.544 MHz clock for T1/J1, or 2.048 MHz for E1. The devices meet, or exceed popular etworking specifications ITU G.703, G.775, and ANSI T1.402. In addition, the devices support the Bellcore GR-499 core and ANSI T1.402. Also, they have a low jitter, on-chip frequency multiplier that provides the necessary clocks to the chip. The master clock that feeds the multiplier can be T1, E1, or lower rates that are frequently available on a board such as 8, 16, 56, 64, 128 and 256kHz.

Other features of the XRT83SL34 family include a parallel microprocessor bus supporting both synchronous and asynchronous microprocessor interfaces for Motorola, Intel and MIPS processors, a crystal-less jitter attenuator that can be switched into either the transmit or receive path, and a quasi random signal synthesizer/detector for support bit error rate testing.
