Exar Doubles E1 Line Interface Unit Capabilities with High-Density 16-Channel Device
FREMONT, Calif., Dec. 12 / -- Exar Corporation (NASDAQ:EXAR), a leading provider of high-performance, mixed-signal silicon solutions for the worldwide communications infrastructure, today introduced the XRT83SL216 a 16-channel E1 Line Interface Unit (LIU). Doubling the capacity of Exar's eight-channel solution (XRT83SL28), the 16-channel device is targeted at Multi-Service Provisioning Platforms (MSPPs), access devices, media gateways, routers, and frame relay access devices.
"The introduction of this 16-channel LIU is another important step in our strategy to leverage our mixed-signal design expertise and further expand our robust industry-leading T1/E1/J1 product portfolio," said Bahram Ghaderi vice president and general manager of Networking and Transmission Products Division. "This device, which incorporates many industry-leading features, offers our customers a wide array of design options."
Product Details
The XRT83SL216 contains 16 independent E1 channels, including independent jitter attenuators and data and clock recovery circuits for each channel. Each channel also supports local analog, remote and digital loopback modes and has on-chip HDB3 encoder/decoders.
The device meets or exceeds popular networking specifications ITU G.703, G.775, ANSI T1.402. and the Bellcore GR-499 core. Other features of the family include a serial processor bus and a crystal-less jitter attenuator that can be switched into either the transmit or receive path. The XRT83SL216 has the patented high impedance circuits that allow the transmitter outputs and receiver inputs to be placed in a high impedance mode when experiencing a power failure.
"Exar's LIU solutions have achieved great success with top vendors in the metro and access markets, and this further confirms our commitment to enhance our product portfolio while offering board and power savings," said Raman Subramanian, director, strategic marketing, Communication Products Division. "The device continues Exar's focus on technology innovation and augments our market position as a dominant T1/E1, T3/E3 and SONET/SDH IC solution supplier."
