摘要
PM8316是PMC -Sierra公司生产的一种低功耗、高性能的多信道E1映射复用成帧芯片。该芯片内部集成了映射器、复用器、成帧器 ,其处理容量为63路E1,并含有8位微处理器总线接口和5个标准信号的JTAG测试端口 ,可支持收发抖动衰减。文中介绍了PM8316的主要功能和接口 ,给出了它在SDH终端设备中的主要信号电路框图。
PM8316which is made by PMC-Sierra Inc is a kind of Multi-channel E1Framer with Mappers and Multiplexers,and low power and high performance are its characteristics.Mappers,Multiplexers and Framer are integrated in PM8316,which it can process up to63E1,provide a8-bit microprocessor bus interˉface and a standard5signal JTAG test port,provide jitter attenuation in tributary receive and transmit direcˉtions.The primary functions and interfaces of PM8316are introduced in this paper,the circuit figures of the chief signals of PM8316in the SDH terminal equipment is also presented.
