XRT83VSH28

•Fully integrated eight channel short-haul transceivers for E1 (2.048MHz) applications
•Internal Impedance matching on both receive and transmit for 75 (E1) and 120 (E1) applications are per port selectable through software without changing components
•Power down on a per channel basis with independent receive and transmit selection
•User programable Arbitrary Pulse mode
•On-Chip transmit short-circuit protection and limiting protects line drivers from damage on a per channel basis
•Selectable Crystal-Less digital jitter attenuators (JA) with 32-Bit or 64-Bit FIFO for the receive or transmit path
•Driver failure monitor output (DMO) alerts of possible system or external component problems
•Transmit outputs and receive inputs may be "High" impedance for protection or redundancy applications on a per channel basis
•Support for automatic protection switching
•1:1 and 1+1 protection without relays
•Receive monitor mode handles 0 to 6dB resistive attenuation (flat loss) along with 0 to 6dB cable loss
•Loss of signal (RLOS) according to ITU-T G.775/ETS300233 (E1)
•Programmable data stream muting upon RLOS detection
•On-Chip HDB3 encoder/decoder with an internal 16-bit LCV counter for each channel
•On-Chip digital clock recovery circuit for high input jitter tolerance
•QRSS/PRBS pattern generator and detection for testing and monitoring
•Error and bipolar violation insertion and detection
•Transmit all ones (TAOS) Generators and Detectors
•Supports local analog, remote, digital, and dual loopback modes
•Supports gapped clocks for mapper/multiplexer applications
•1.8V Inner Core
