PM5309中文资料TBS-2488 Backplane Interface & Cross-Connect数据手册Microchip规格书

描述 Description

The PM5309 TBS-2488 is a high performance backplane interface and cross-connect solution for 2.5G line cards in SONET/SDH systems.

Applications
• Multi-service Provisioning Platforms
• SONET/SDH Digital Cross-connects
• SONET/SDH Add/Drop and Terminal Multiplexers

特性 Features

Provides one low-speed parallel TelecomBus interface operating at 32 bits x 77.76 MHz
Provides three high-speed multi-rate serial backplane interfaces
Supports CLOS and memory-based switch fabric systems
Supports linear, UPSR, and BLSR protection strategies
Implements a 10G memory switch fabric with STS-1/AU-3 switching granularity in a single device
Supports non-blocking anycast switching between any of the serial or parallel interfaces
Provides two pages of connection memory with software and hardware controlled hitless page swaps at frame boundaries
Provides integrated delay management that allows for arbitrary SONET/SDH frame alignments on each ingress serial link
Supports three RASIO 3G high-speed serial backplane interfaces for interfacing with SONET/SDH cross-connects, framers, mappers, and other TBS-2488 devices
Each high-speed serial backplane interface is capable of independent operation at 4x622 Mbit/s scrambled NRZ SONET/SDH, 4x777 Mbit/s Serial TelecomBus, or 1x2488 Mbit/s scrambled NRZ SONET/SDH
Supports one 32-bit or four 8-bit 77.76 MHz TelecomBus interfaces to interface with parallel TelecomBus framers and mappers
Integrated pointer interpreter reduces complexity of external framers and mappers by asserting payload, J0, and J1 indications on the outgoing TelecomBus interface
Allows insertion and extraction of TOH bytes through a dedicated low speed serial interface
Low power 1.2 V CMOS core with 2.5 V or 3.3 V CMOS/TTL selectable digital I/O
Generic 16-bit microprocessor bus interface and full suite of interrupts for configuration, control, and status monitoring
