Dear：
ADV7179 out put PAL VIDEO more than 30S， When power on .I use FPGA trans VIdeo data to ADV7179. IF power on， FPGA trans video data to ADV7179 immediately， But ADV7179 out put normal picture more then 30 seconds，Test found output blanking signal after config done，When Temperature rise after a period of time，ADV7179 out put normal picture.
My schematic reference Technical Manual， Register configuration from Table 24. PAL B/D/G/H/I (FSC = 4.43361875 MHz) of datasheet， Why is this phenomenon？
