**Shenzhen SCTF Elec** · Oscillators · SMD2520-4P

SX2M25.000M20F30TNN from Shenzhen SCTF Elec, 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 | Output enable (OE): output is enabled if OE is logic "1" (>=0.7Vdd) or open, and disabled if OE is logic "0" (<=0.3Vdd). |
| 2 | GND | power_in | Ground connection for the 2.5x2.0 mm (2CM series) oscillator. |
| 3 | Output | output | CMOS clock output rated for a 15 pF load, with VOH min 0.9Vdd and VOL max 0.1Vdd. |
| 4 | Vdd | power_in | Supply voltage pin, 1.62V to 3.63V, with a 0.01 uF decoupling capacitor shown in the test circuit. |

## CAD (KiCad official)

- Symbol: `SX2M25.000M20F30TNN`
- Footprint: `Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm`
- 3D model: SMD2520-4P (KiCad packages3D, STEP)
- 3D model files: `sx2m25-000m20f30tnn-etched.step` / `sx2m25-000m20f30tnn-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sx2m25-000m20f30tnn.step` / `sx2m25-000m20f30tnn.glb` are the bare package body.
