　Hittite公司以创新的设计使得其PLL产品性能优异，在相位噪声，杂散方面有着卓越表现，其芯片的高集成度使得外围电路简单，设计方便。所以随着电子技术的发展，对频率源的相位噪声性能要求越来越高，Hittite的低相位噪声PLL，在物理、天文、无线电通信、雷达、航空、航天以及精密计量、仪器、仪表等各种领域里都将大有用武之地。(The Hittite companies with innovative design makes the PLL excellent product performance, the phase noise, spurious aspects with excellence, its high integration chip makes the peripheral circuit is simple and easy design. So with the development of electronic technology, phase noise performance of frequency source is more and more high, the Hittite low phase noise PLL, in physics, astronomy, radio communication, radar, aviation, aerospace and precision measurement, instruments, meters and other fields will be great.)

51单片机SCMrtoss源代码，非常好用的能够移植 (51 the microcontroller SCMrtoss source code, very useful to be able to transplant)

这是Small RTOS 51 在DP－51下载仿真实验仪上使用CAT24WC02驱动程序的例子。本例程序按照相应的的通讯协议接收一个数据，并将接收到的数据显示到LED数码显示器上。然后将接收到的数据写入Cat24Wc02中，再在同一位置将数据读出，并将读出的数据通过串口发送回来。通讯协议参考rtos随想曲和test.ini。 (This is the Small RTOS 51 DP-51 download simulation NG use CAT24WC 02 Driver for example. The cases in accordance with the relevant procedures of receiving a communication protocol data and receiving the data shows that the LED digital display. Then sending the data into Cat24Wc02, again in the same position will be read out data, will be read out through the serial data sent back. Communication protocol reference rtos test.ini and Capriccio.)
