DM6467 tvp5147m1 composite 视频采集的问题

Other Parts Discussed in Thread: TVP5147M1, TVP7002, TVP5147, TVP5150

     我们有一块自己设计的DM6467的板子,使用tvp5147m1解码芯片,视频源为PAL信号输入,

tvp5147m1配置为BT.656模式,输出端为 vpif channel 0 ,(原理图与开发板类似,但不含有tvp7002与cpld),

实际检测过 DATACLK 时钟为27Mhz,XTAL1外部连接的晶振为14.3Mhz

寄存器配置项见附件:

   

采集出来的图片效果:
