When operating the RV-3049 without Backup Supply Voltage, it is recommended to tie VBACKUP pin to GND,
10 kOhm resistor is recommended.
2
Pull-up resistor of the INT signal can be tied directly to supply voltage VDD.
3
CLKOUT is enabled when CLKOE input is high. It either can be permanently enabled with a pull-up resistor
to supply voltage VDD or actively controlled by the µController.
If no clock function is needed, it is recommended to disable CLKOUT by permanently tie CLKOE pin with a
pull-down resistor to GND.

When operating the RV-3049 with either Supercap or Lithium Battery as Backup Supply, the INT signal
also works when the device operates on VBACKUP supply voltage. Therefore it is recommended to tie the
INT
pull-up resistor to VBACKUP.
5
When a Lithium Battery is used, it is recommended to insert a protection resistor of 100 - 1’000 Ohm to
limit battery current and to prevent damage in case of soldering issues causing short between supply pins.
