PM5369 Datasheet, PDF (1/2 Pages) PMC-Sierra, Inc – Tributary Unit Payload Processor for 9953 Mbit/s

Released
Tributary Unit Payload Processor for 9953 Mbit/s
PM5369
TUPP 9953
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, high-
order 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.
