ADV7179
A design with adv7179 on new zynq board. adv7179 be configed color bar,color with enable . It can not display normally, without any color information(figure1 ). But color with disable,it can display normally(figure2 ). The same config with ADV7179 on the…

Hello;
We encountered the following problems in developing our product; could you help take a look, please?
The HDMI signal output by Hisilicon SOC is transmitted to ADV7604 and converted to BT656, and then input to ADV7179 and converted to CVBS signal…
请教大家1个问题:
我采用FPGA发送数据给ADV7179 输出PAL视频信号,ADV7179电路完全参考器件手册,寄存器配置也来自器件手册PAGE50, FPGA开机 1s启动,送数给ADV7179,data接口时序正确,现在发现冷机开机ADV7179要等几十秒才能显示图像,示波器测试了上电后ADV7179输出的全是消隐信号,等几十秒后才慢慢输出正确的视频信号,而且开始的视频图像有雪花点,再过10多秒图像完全正常,如果设备一直通电,关电后立马开机,1s钟就能出正确图像,我使用的是工业级芯片…
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…
HI All,
I was facing the same issue with ADV7179(Some colors are missing,when we enable bar pattern.)
Input clock frequency to ADV7179 - 27MHz from FPGA.
Voltage levels are proper,Ref voltage to ADV7179 - 1.22V.
I am getting all the I2C read ack when…
