Hello

 

I am  using ADV7180 in a video capture project.

 

My cammera`s output is PAL 720*544 which  i want to connect  to ADV7180.

 

I connect ADV7180 chip  to Xilinx Spartan3 FPGA and  program its registers via I2C.

 

i have a problem when i connect my cammera to ADV7180.

the problem is that  when  i check stus register 0x10 data,  Fsc lock bit some times is high and some times is low.,  means not locked.

 

alos  when i reset chip via I2C ,  teh chip stays at reset state and does not work  more.

 

please help me how can i check that my cammera`s video is detected by ADV7180 correctly or not.( I have  not video encoder)

 

Thanks.
