Intel 82530串行通信控制器(SCC)是双通道多规程数据通信外围芯片。SCC的作用是串行一並行,並行一串行转换器/控制器的作用(英文为SERIAL COMMUICATIONSCONTROLLER,缩写为SCC)。SCC可以在硬件构成上满足串行通讯的应用。SCC含有新颖的完善的内部功能。这些功能包括片内波特率发生器,数字锁相环、各种数据编码、译码电路以及晶体振荡器,这大大减少了外部逻辑的开销。除此之外,诊断能力即自动回波和本地反循环,使用户能检测和隔离在网络中的故障。这种诊断能力大大提高了系统的可靠性和可维护性。
The Intel 82530 Serial Communications Controller (SCC) is a dual-channel multi-protocol data communications peripheral chip. The role of the SCC is to serially and parallelize the role of a serializer / controller (in English, a SCIAL COMMAND SCONTROLLER, abbreviated as SCC). SCC can meet the application of serial communication in the hardware structure. SCC contains a novel and complete internal function. These features include an on-chip baud rate generator, a digital phase-locked loop, a variety of data encoding, decoding circuitry and crystal oscillator, which greatly reduces the overhead of external logic. In addition, diagnostic capabilities such as automatic echo and local reverse cycling enable users to detect and isolate faults in the network. This diagnostic capability greatly improves the reliability and maintainability of the system.
