Rise time of power supply : 100µs or less
This method has the possibility that the Reset section of turning on the power supply can not satisfied. cannot be satisfied.
Please design the set considering the characteristic of the power supply enough.
◆ Notes when CR is inserted between V
◆
Please note that there is a possibility that reset section (1µs) can not be satisfied because the power supply is turned on when the rise time of VCC is slow
When VCC is turned off, the DVI voltage becomes higher than VCC voltage but IC destruction is not occurred if recommended constant
(R1 = 1kOhm, C1 = 1µF) is used.
Please note that there is a possibility that Reset section (1usec) cannot be satisfied if wait time is not enough long after turning off VCC.
(It is necessary to consider DVI voltage level after turning off VCC.)
①The rise time to 0→2.4V of VCC must use the power supply of 100µs or less.
②Please wait 25ms or more after VCC turn off (VCC <= 0.05V), because it is necessary to secure reset section (1µs or more).
