PM4325 Description
OCTLIU ST Octal Short Haul T1/E1/J1 Low Latency Transport Line Interface.
PM4325 Key Features
- Monolithic device integrating eight T1/J1 or E1 short haul line interface units
- Software switchable between T1/J1 and E1 operation on a per-device basis
- Optional encoding/decoding of B8ZS, HDB3, and AMI line codes
- Provides receive equalization, clock recovery, and line performance monitoring
- Provides transmit and receive jitter attenuation
- Provides digitally programmable pulse templates
- Provides a selectable, per channel independent de-jittered T1 or E1 recovered clock for system timing and redundancy
- Provides PRBS generators and detectors on each tributary for error testing at DS1 and E1 rates as remended in ITU-T O.15
- Uses line rate system clock
- Recovers clock and data using a digital phase locked loop for high jitter tolerance
