摘要

155mbps (stm - 1电气)收发器符合ITU-T的相关建议。传输通道具有CMI传输(无变压器)，具有指定的抖动产生。在接收端，获得了抖动容忍和误码率性能。电缆均衡器支持13.7 dB损耗(奈奎斯特频率)，闭眼时间小于600 psec。该设备使用一个主时钟(155 MHz)和一个DLL用于TX和RX同步。采用0.35 /spl mu/m的BiCMOS技术实现了有针对性的串扰隔离性能。由3.3 V供电的TQFP48 IC消耗390 mW。

A single chip 155 Mbps/140 Mbps SDH/PDH transceiver

The 155 Mbps (STM-l electrical) transceiver complies with the relevant ITU-T recommendations. The transmit channel features CMI transmission (transformerless) with specified jitter-generation. On the receiver side, jitter-tolerance and bit error rate performance is attained. A cable equalizer supports 13.7 dB loss (Nyquist-frequency) and has an eye-closure less than 600 psec. The device uses one master-clock (155 MHz) and a DLL for both TX and RX synchronization. Targeted crosstalk isolation performance is achieved with a 0.35 /spl mu/m BiCMOS technology. The TQFP48 IC powered from 3.3 V consumes 390 mW.
