**Yangxing Tech** · Oscillators · SMD2520-4P

OT252026MJBA4SL from Yangxing Tech, 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 pin: output enabled at 70% of VDD min or floating, disabled (Hi-Z) at 30% of VDD max or GND. |
| 2 | GND | power_in | Ground; a 0.01uF to 0.1uF or higher capacitor is required between VDD and GND. |
| 3 | OUTPUT | output | CMOS clock output rated for a 15pF load, with Voh 90% VDD min and Vol 10% VDD max. |
| 4 | VDD | power_in | Supply voltage pin, 1.8V to 3.3V. |
