Microchip Technology PM5369-FGI

FEATURES

• Configurable, multi-channel payload processor for aligning SONET virtual tributaries (VTs) or SDH tributary units (TUs) in an STS-192/STM-64 or STS-48/STM-16 data stream.
• Supports High Order (STS/AU) pointer processing, payload processing, and path termination/monitoring.
• Supports Low Order (VT/TU) pointer processing, payload processing, and path monitoring.
• On the line side, provides working Serial Receive and Transmit ESSI (Extended SONET Serial Interface) CML links. Links are configurable as:
• 4xSTS-48/STM-16 2488.32 Mbit/s SONET/SDH framed interfaces; or
• 4xSTS-12/STM-4 622.08 Mbit/s SONET/SDH framed interfaces.
• On the system side, provides working Add and Drop Serial ESSI links. Links are configurable as:
• 4xSTS-48/STM-16 2488.32 Mbit/s SONET/SDH framed interfaces; or
• 4xSTS-12/STM-4 622.08 Mbit/s SONET/SDH framed interfaces.
• Independently configurable (2488.32 Mbit/s or 622.08 Mbit/s) Line and System Interfaces.
• Provides a set of Ingress and Egress shared protection links.
• Provides a per-link Space switch on egress interfaces.
• Provides a steady-state latency of:
• 21 µs from line Receive to system DROP for VT1.5.
• 2.5 µs from system ADD to line TX.
• Provides hardware based Message Assisted Protection Switching (MAPS) support to work with a centralized fabric (e.g. PM5370 WSE 40).
• Supports independent Line Receive and System Drop transport frame alignment for high-order traffic.
• Supports independent transport, highorder payload and tributary multi-frame alignments for low-order traffic.
• Supports independent Line Transmit and System Add transport frame alignments.
• On the receive path, provides optional SDH payload conversion of:
• AU4/VC4/TUG3/TU3/VC3/C3 to AU3/VC3/C3; or
• AU3/VC3/C3 to AU4/VC4/TUG3/TU3/VC3/C3; or
• AU4/VC4/TUG3/TUG2 to AU3/VC3/TUG2; or
• AU3/VC3/TUG2 to AU4/VC4/TUG3/TUG2.
• On the transmit path, provides optional SDH payload conversion of:
• AU3/VC3/C3 to AU4/VC4/TUG3/TU3/VC3/C3; or
• AU4/VC4/TUG3/TUG2 to AU3/VC3/TUG2; or
• AU3/VC3/TUG2 to AU4/VC4/TUG3/TUG2.
• Allows for low order (VT/TU) processing bypass.
• Supports high-order ESSI transport overhead transparency.
• Supports line and system diagnostic and facility loopbacks.
• Provides optional PRBS generation and monitoring features for ESSI offline link verification.
• Provides a generic 16-bit microprocessor bus interface for configuration, control, and status monitoring.
• Provides a standard 5-signal IEEE 1149.1 JTAG test port for boundary scan test purposes.
• Implemented in a 1.2 V core and 2.5 V I/O 0.13µm CMOS technology. Inputs are 3.3 V tolerant.
• Packaged in a 672-ball FCBGA top-hat, 27 mm x 27 mm.
• Power when full bandwidth is used (OC-192/STM-64 applications using 2.488 Mbit/s links) is 6.91 W typical.
• Power when 1/4 bandwidth is used (OC-48/STM-16 applications using 622 Mbit/s links) is 2.64 W typical.
