REV. P1.0.0

8-CHANNEL E1 SHORT-HAUL LINE INTERFACE UNIT

FEATURES

• Fully integrated eight channel short-haul transceivers for E1 (2.048MHz) applications

• Internal Impedance matching on both receive and transmit for 75Ω (E1) and 120Ω (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

• 3.3V I/O Supply Operation

• 225 ball BGA package

• -40°C to +85°C Temperature Range
