Applications
• SONET/SDH Add-Drop Multiplexer (ADM)
• SONET/SDH Digital Cross-connect (DCC)
• Multi-service Provisioning Platform (MSPP)
• Multi-service ADM (MS-ADM)
• Multi-service Switch (MSS)
• Optical Access Mux
• Terminal Multiplexers

特性 Features

Multi-purpose SONET/SDH VT/TU and SONET/SDH STS/STM crossconnect
With a memory-switch architecture, implements a strictly nonblocking switch that supports a VT/TU level fabric of up to 45 Gbit/s
Supports 18 high-speed Enhanced SONET Serial Interface (ESSI) CML links each independently configurable for STS-48/STM-16 at 2.488 Gbit/s or STS-12/STM-4 at 622.08 Mbit/s operation
Supports system frame synchronization using an external frame pulse or ESSI smart frame synchronization using the frame boundary of the receive links
Compensates for differences in frame boundary arrival times between ingress ports using FIFOs and device level software configurable delay registers
Each SONET STS-1 or SDH VC3/VC4-TUG3 may be independently configured as a single unit and/or as a container of VT/TUs. The contents may be switched intact or switched as VT/TUs
Allows each SONET VT Group to be independently configured to carry VT1.5, VT2, VT3, or VT6 tributaries
Allows each SDH TUG2 to be independently configured to carry TU11, TU12, or TU2 tributaries
Provides a device latency of 5.62 (+/-0.17) µs for 2.488 Gbit/s links and 6.21 (+/-0.67) µs for 622 Mbit/s links Supports extraction of the transport overhead (TOH) from the ingress ports (both high and low-speed) as well as the insertion of transport overhead into the egress ports via low bandwidth two-bit 77.76 MHz interfaces
Supports a hardware-based Automatic Protection Switching mechanism (MAPS) for centralized link protection control when operating with other Microchip devices such as the PM5369 TUPP-9953
Provides fully automatic protection switching for Class 1 protection services including 1+1 protection, UPSR, SNCP, and static mesh protection services
Provides hardware assists for Class 2 protection services including 1:N protection, BLSR-2/4, MSSPRING-2/4, and dynamic mesh protection schemes
All high-speed ingress and egress links are 1.2 V CML and are ELVDS-compatible with programmable pre-emphasis on transmit, equalization on receive, and support for both AC and DC coupled interfaces
Each high-speed link supports SONET/SDH framed or unframed PRBS-23 or PRBS-7 generation and monitoring for off-line link verification
Configured, controlled, and monitored using a generic 32-bit microprocessor interface
Provides a standard 5-signal IEEE 1149.1 JTAG test port for boundary scan test purposes
Implemented in 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 27mm
