which voltage specification do the ADV7391 I2C and CLKIN signals follow? I'm assuming it is the Vdd_io?
The CLKIN and sync inputs will work at 1.8V. We're still checking into whether the I2C lines will work at 1.8V.
Those 2 signals are 3.3V compliant. If you don't have the reference schematics, I can attach them.
I was hoping to run the CLKIN, SDA, SCL, HSYNC, VSYNC and pixel data from a 1.8V FPGA. The datasheet states that digital inputs/outputs can be operated at 1.8V, does that cover all the signals I have detailed?
Finally got confirmation, HS, VS and the I2C lines should all work at 1.8V when DVDDIO is at 1.8V.
