SGS-THOMSON Microelectronics将在香港推出一种初级速度控制器集成电路,以取代双片式解决办法,降低综合服务数字网络(SDN)开关系统和中央办公室中继卡的费用。 CMOS STLC5432电路直接把脉冲码调制(PCM)多路总线封接到2M bit/s级通信线路上,它适用于所有使用2.048M bit/s PCM传输的领域。它提供了一个符合欧洲邮电与通信协会(CEPT)标准的从PCM总线接到变换器的单片式解决办法。另外,由于
SGS-THOMSON Microelectronics will launch a primary speed controller IC in Hong Kong to replace two-chip solutions to reduce the cost of Integrated Services Digital Network (SDN) switching systems and central office trunk cards. The CMOS STLC5432 circuit directly encapsulates a pulse code modulation (PCM) multiplexed bus onto 2M bit / s communication lines and is suitable for all applications where 2.048M bit / s PCM is used. It provides a monolithic solution from the PCM bus to the converter in compliance with European Telecommunications and Telecommunications Association (CEPT) standards. In addition, due
