The DVI terminal is an asynchronous reset terminal. Please note that there is a possibility that IC doesn't operate normally
if the reset section is not installed after the start-up of V
(Please refer to the paragraph of "Timing chart for V
The description concerning SDA and the terminal SCL is omitted in this application circuit example. Please design the
application the standard of the I2C bus as it finishes being satisfactory. Moreover, the description concerning the terminal
ADDR is omitted. Please refer to the paragraph of "Timing chart for V
ADDR design.
ex 1) The control signal line such as CPU is connected.
ex 2) Reset IC is used.
ex 3) A different power supply is used.
※ Power supply of DVI must stand up later than power supply of VCC stand up, because it is necessary to secure reset section ( 1µs or more ).
1, For Reset IC of the Push-Pull type
2, For Reset IC of the Open drain output
