DESCRIPTION
1 X1 The input of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz quartz crystal.
X1 also can be driven directly from a 32.768kHz source with no crystal connected.
2 X2 The output of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz quartz crystal.
X2 should be left open when X1 is driven from an external source.
3 VBAT Battery voltage. This pin provides a backup supply voltage to the device. VBAT supplies power to the device in the
event that the VDD supply fails. This pin should be tied to ground if not used.
4 GND Ground.
5 AC AC Input. The AC input pin accepts either 50Hz of 60Hz AC 2.5VP-P sine wave signal.
6 LV Low Voltage detection output/Brownout Alarm. Open drain active low output.
7 EVIN Event Input - The EVIN is a logic input pin that is used to detect an externally monitored event. When a high signal
is present at the EVIN pin, an “event” is detected.
8 EVDET Event Detect Output. Active when EVIN is triggered. Open Drain active low output.
9 FOUT Frequency Output. Register selectable frequency clock output. CMOS output levels.
