YXC Crystal Oscillators · Crystal Oscillators · SMD2520-4P

OK3EL89CJI-111YLC-32.768K from YXC Crystal Oscillators, in a SMD2520-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Tri-state input Tri-state/output enable input (OE); output enabled when high (≥70% of VDD) or floating, disabled when low (≤30% of VDD) or tied to GND.
2 GND power_in Ground; a 0.01 µF to 0.1 µF or higher capacitor is required between VDD and GND.
3 OUTPUT output CMOS clock output at 32.768 kHz, specified for a 15 pF load with VOH of 90% VDD min and VOL of 10% VDD max.
4 VDD power_in Supply voltage of 1.8 V to 3.3 V; a 0.01 µF to 0.1 µF or higher bypass capacitor to GND is required.
