Hi,
I am using ADV 7403 Video Decoder in my design to convert the YC(luma and chroma) Analog Input signal to Digital signal in BT .656 standard.
I have powered-on my system. I have found few observations while doing this,
1. ADV 7403 dissipates lot of heat. I have checked the temperature using thermal camera and it reached upto 70 deg C.
2. AVDD - Analog Supply Voltage (3.3 V) consumes heavy current compared to other power supplies.
Please find the attached schematic for reference.
In ADV 7403 User manual, there is a bunch of Power-save mode options. I am not sure which one is applicable to my design.
Please suggest me how I can reduce the device power consumption by turning off the other unused ADCs without affecting required functionality.
I am waiting for your valuable inputs, suggestions or recommendations.
Regards,
Murali P T
