10/9/2002 - Exar, a leading provider of high-performance, mixed-signal silicon solutions for the worldwide communications infrastructure announced its innovative R3 (Reconfigurable, Relayless Redundancy) technology, and the expansion of its T1/E1/J1 offerings with the introduction of three new low power, highly integrated short haul LIUs. The new single, four and eight-channel devices (XRT83SL30 / XRT83SL34 / XRT83SL38) are targeted at Multi-Service Provisioning Platforms (MSPPs), access devices, media gateways, routers, and frame relay access devices.
What is R3 Technology?
Distancing it from competitive offerings, Exar's R3 Technology (Reconfigurable, Relayless Redundancy) delivers key innovative features to customers designing T1/E1/J1 interface cards. The devices are Reconfigurable with integrated termination supporting all common T1/E1/J1 line impedances (75/100/110/120 ohms) enabling customers to build one board with a single bill-of-materials. 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 or card that can be brought on-line in the event of failure.
"Leveraging these two key benefits: single bill-of-material (reconfigurable termination) and relayless redundancy can simplify board layout, inventory requirements and reduce costs," said Dr. Roubik Gregorian, executive VP and general manager Communications Division, CTO. "These features are unique to the marketplace, and significantly differentiate Exar's offering."
The devices meet or exceed popular networking specifications ITU G.703, G.775, ANSI T1.402. and the Bellcore GR-499 core. Other features of the 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. Also, because of their inherent flexibility and standards compliance, the LIUs can be used in conjunction with any T1/E1/J1 framer whether it is Exar's eight-channel framer, the XRT84L38, or a customer's specific device. "These new R3 Technology short-haul devices, along with our already deployed short-haul/long-haul (XRT83Lxx) LIUs, leverage our latest T1/E1/J1 semiconductor innovations, and build on the strong market acceptance of our T/E products," said Hugh Wright, director of marketing.
Prices, Packages and Availability
Samples of the XRT83SL34 and XRT83SL38 are available now with samples of the single channel part, the XRT83SL30, available in November, 2002. The eight-channel device is offered in a 208-pin TQFP, the four-channel in a 128-pin TQFP, and the one-channel in a 64-pin TQFP. The devices operate at 3.3V with 5V tolerant I/Os over the industrial temperature range. In 1,000 piece quantities, the XRT83SL38 is $48.24, the XRT83SL34 is $25.39 and the XRT83SL30 is $9.03.
