E1控制器

The DS2143 is a comprehensive, software-driven E1 framer. It is meant to act as a slave or coprocessor to a microcontroller or microprocessor. Quick access through the parallel control port allows a single micro to handle many E1 lines. The DS2143 is very flexible and can be configured into numerous \n• E1/ISDN-PRI framing transceiver \n• Frames to CAS, CCS, and CRC4 formats \n• Parallel control port \n• On-board two frame elastic-store slip buffer \n• Extracts and inserts CAS signaling bits \n• Programmable output clocks for fractional E1 links, DS0 loopbacks, and drop and insert applications ;

3.3V、E1/T1/J1四线路接口

DS21448是一款四端口E1或T1线路接口单元(LIU)，适用于短程和远程应用。它将四个独立的发送器与四个独立的接收器整合到一片144引脚PBGA或128引脚LQFP封装内。发送驱动器可在75Ω或120Ω应用中产生满足G.703 E1要求的波形，对于T1应用提供0dB、-7.5dB、-15dB和-22.5dB的DSX-1或CSU线路补偿。 \n• 四个完整的E1、T1或J1 LIU \n• 支持长距离与短距离主干线 \n• 内部软件可选接收侧终端，以用于75Ω/100Ω/120Ω \n• 3.3V电源供电 \n• 32位或128位晶体抖动衰减器，在E1与T1应用中仅需一个2.048MHz MCLK，在T1应用中也可以选择采用1.544MHz MCLK \n• 对于E1，产生有或没有回波损耗的线路补偿，对于T1，产生DSX-1与CSU线路补偿 \n• AMI、HDB3与B8ZS编码/解码 \n• 16.384MHz、8.192MHz、4.096MHz或2.048MHz时钟输出合成自恢复时钟 \n• 接收器可编程监视器模式 \n• ;
