They must be properly decoupled for low noise and ripple. 3 IO voltage supply must be fixed with respect to external processor's IO supply voltage levels used in the application. It can be set to any value within min and max. operating voltage. 4 When device is operated at max fDCS frame rate, DCLK at 40MHz, driving loads 15pF each. 5 I2C pins SCL and SDA are open-drain outputs and need termination (Pull-up resistor) according to I2C standards. 6 VOH/OL and IOH/OL values are measured at max CIO and max fIO. 7 Value is without termination resistors © 2017 ESPROS Photonics Corporation Characteristics subject to change without notice 5 / 97 Datasheet_epc635-V1.02 www.espros.com |
