摘要：技术简介7提供了一个8MHz的系统背板使用Dallas半导体/ Maxim的DS2152和DS2154 T1/E1单芯片收发（ SCT的）复用的PCM流的要求。 DS2155 ， DS26528 ， DS26524 ， DS26522 ， DS26521 ， DS26519和DS26518中都含有国际文凭组织的功能，无需外部电路，并建议用于新设计。Maxim > App Notes > COMMUNICATIONS CIRCUITS Keywords: T1, E1, T1/E1, 8MHz, backplane, PCM, pulse code modulation, elastic store, DS0, 2.048MHz, Apr 05, 2001 system clock, framer, byte interleaved, IBO, interleave bus operation, SCTs, single chip transceivers, stream APPLICATION NOTE 561 Tech Brief 7: DS2152 and DS2154 8MHz System Clock Operation Abstract: Tech Brief 7 provides the requirements for multiplexing four PCM streams into one 8MHz system backplane using the Dallas Semiconductor/Maxim DS2152 and DS2154 T1/E1 single chip tranceivers (SCTs). The DS2155, DS26528, DS26524, DS26522, DS26521, DS26519 and DS26518 all contain IBO functionality without external circuitry and are recommended for new designs. The DS2152 and DS2154 PCM signals can interface to an 8 MHz system……
