图像实时处理中的高性能锁相环

High performance phase locked loop for the image real time processing

论述了ＴＩ公司的高频锁相环芯片ＴＬＣ２９３２Ｉ的工作原理及特点，并且给出了该芯片在图像高速数字化累积系统中的应用。该系统的锁相环路部分只需设置一个电阻便可得到相应频率的相位锁定的系统主频，这种芯片特别适合于数字图像高速实时处理中的视频锁相。

The principle and features of a high performance phase locked loop, TLC2932I produced by Texas Instruments company, is described , and an application of the chip in the high speed image digital accumulation system is also described. In the phase locked loop section,only need to set the bias resister a value according to the required system clock. This chip is very effective in the high speed digital image real time processing system.
