SONET/SDH Interface for 622 & 155 Mbit/s
PM5319
ARROW 622
Released
FEATURES
SONET/SDH INTERFACE
• Interface rate software selectable
between OC-3/STM-1 (155.52 Mbit/s)
and OC-12/STM-4 (622.08 Mbit/s)
rates
• Integrated clock recovery & synthesis
allows direct interface to low-cost
optical transceivers
• Integrated clock synthesis generates
line clock from 77.76 MHz reference
• Complies with Bellcore, ANSI, and ITU
specifications for Jitter Tolerance and
Jitter Generation
• High order path processing and
alignment to STS-1/AU-3/TU-3 level
• Full access to all SONET/SDH
Transport overhead bytes via a
dedicated serial port
• Full access to all SONET/SDH STS-
1/AU-3/TU-3 path overhead bytes via a
dedicated serial port
• Full access to all DCC bytes via a
dedicated serial interface
• Ring Control port provides real time
detection of error conditions and
insertion of alarms such as AIS & RDI
• Section and Path Trace filter and
monitor checks for Trace Identifier
Mismatch (TIM) and Trace Identifier
Unstable (TIU) conditions
DS3/E3/EC-1 INTERFACE
• Flexible three-port DS3/E3/EC-1
Interface
• Supports clear channel
mapping/demapping of DS3 or E3
into/from STS-1, AU-3, or TU-3
• Fully digital desynchronizers require
no external PLLs for standards-
compliant operation
• Integrated desynchronization CSU
allows low rate reference clock at
44.736 MHz, 34.368 MHz, or 51.84
MHz
• Bi-directional digital jitter attenuation
for DS3 and E3 streams allows
interfacing to low cost LIUs
• Full bi-directional performance
monitoring for DS3, E3, and EC-1
streams
• Full access to DS3/E3/EC-1 Overhead
bytes
GENERAL FEATURES
• Provides an industry standard 8-bit,
77.76 MHz telecombus interface
• Multi-drop capability allows multiple
devices to share the add/drop bus for
redundancy or multiplexing purposes
• Full Time Slot Interchange (TSI) allows
flexible mixing of traffic from the
SONET/SDH and DS3/E3/EC-1
Interfaces
• Supports diagnostic 223-1 pseudo-
random bit-sequence (PRBS)
generation and monitoring
• Provides a standard JTAG test-port for
boundary scan board-test purposes
• Provides a generic 16-bit
microprocessor interface for control
and monitoring
• 15x15mm 196 ball CABGA package
allows for flexible placement and
routing
APPLICATIONS
• SONET/SDH Add/Drop Multiplexers
• Terminal Multiplexers
• Customer Premise Equipment
• Media Gateways
• Multiservice Provisioning Platforms
• Channelized Router Interfaces
• Digital Cross-Connects
