●Timing chart for VCC and DVI power supply sequence

DVI is I

2C bus reference voltage terminal. And it is also asynchronous reset terminal. In DVI 'L' term, internal state is set to

Power Down mode.Initial reset is not necessary, because power on reset function is included in this product. DVI supply with

VCC supply, or after VCC supply. Please do not become DVI＞VCC.

1) Recommended Timing chart1 for VCC and DVI supply.

2) Recommended Timing chart2 for VCC and DVI supply.

( If DVI can not supply with VCC supply )
