chips. They provide phase noise performance as low
as –125dBc at 1kHz offset (at 155MHz) and a typical
RMS jitter of 4pS RMS ( at 155MHz ). They accept
fundamental parallel resonant mode crystals from 12
to 25MHz.

概述： 介绍一种CAN-bus网络与以太网连接，构成一个中型远程监控/数据传输网络的方法。
CAN（Controller Area Network——控制器局域网）是一种由CAN控制器组成的高性能串行数据局域通信网络，是国际上应用最广泛的现场总线之一。它最早由德国Bosch公司于1984年推出，最初用于汽车内部测量与执行部件之间的数据通信。CAN-bus总线模型符合OSI的7层结构...[详细]
