PM5320
Preliminary
SONET/SDH Interface for 155 Mbit/s
ARROW 155
Sꢀ Ring Control port provides real time
detection of error conditions and
insertion of alarms such as AIS & RDI
Sꢀ Section and Path Trace filter and
monitor checks for Trace Identifier
Mismatch (TIM) and Trace Identifier
Unstable (TIU) conditions
SONET/SDH Interface
Sꢀ SONET/SDH interface for OC-
3/STM-1 (155.52 Mbit/s) rates.
Sꢀ Integrated clock recovery &
synthesis allows direct interface to
low-cost optical transceivers
Sꢀ Integrated clock synthesis
generates line clock from 77.76
MHz reference
General Features
Sꢀ Provides an industry standard 8-bit,
77.76 MHz telecombus interface
Sꢀ Multi-drop capability allows multiple
devices to share the add/drop bus for
redundancy or multiplexing purposes
Sꢀ Full Time Slot Interchange (TSI)
allows flexible mixing of traffic from
the SONET/SDH and DS3/E3/EC-1
Interfaces.
DS3/E3/EC-1 Interface
Sꢀ Flexible three-port DS3/E3/EC-1
Interface
Sꢀ Complies with Bellcore, ANSI,
and ITU specifications for Jitter
Tolerance and Jitter Generation
Sꢀ High order path processing and
alignment to STS-1/AU-3/TU-3
level
Sꢀ Supports diagnostic 223-1 pseudo-
random bit-sequence (PRBS)
generation and monitoring.
Sꢀ Supports clear channel
mapping/demapping of DS3 or E3
into/from STS-1, AU-3, or TU-3
Sꢀ Fully digital desynchronizers require no
external PLLs for standards-compliant
operation
Sꢀ Provides a standard JTAG test-port
for boundary scan board-test
purposes.
Sꢀ Full access to all SONET/SDH
Transport overhead bytes via a
dedicated serial port
Sꢀ Provides a generic 16-bit
microprocessor interface for control
and monitoring.
Sꢀ Integrated desynchronization CSU
allows low rate reference clock at
44.736 MHz, 34.368 MHz, or 51.84
MHz
Sꢀ Full access to all SONET/SDH
STS-1/AU-3/TU-3 path overhead
bytes via a dedicated serial port
Sꢀ Full access to all DCC bytes via a
dedicated serial interface
Sꢀ 15x15mm 196 ball CABGA package
allows for flexible placement and
routing
Sꢀ Bi-directional digital jitter attenuation
for DS3 and E3 streams allows
interfacing to low cost LIUs
Sꢀ Full bi-directional performance
monitoring for DS3, E3, and EC-1
streams.
