Exar Doubles E1 Line Interface Unit Capabilities With High-Density 16-Channel Device
The XRT83SL216 is 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 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.
