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

SX2M50.000E20F30THN 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 | Tri-state/output enable input (OE): output is enabled when high (Logic 1, ≥0.7Vdd) or open and disabled when Logic 0 (≤0.3Vdd, connected to GND). |
| 2 | GND | power_in | Ground connection for the oscillator. |
| 3 | Output | output | CMOS clock output, 15 pF typical load, VOH min 0.9Vdd and VOL max 0.1Vdd. |
| 4 | Vdd | power_in | Supply voltage input, 0.8 V to 2.0 V (1.2 V typ.); a 0.01 uF bypass capacitor is shown in the test circuit. |

## CAD (KiCad official)

- Symbol: `SX2M50.000E20F30THN`
- Footprint: `Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm`
- 3D model: SMD2520-4P (KiCad packages3D, STEP)
- 3D model files: `sx2m50-000e20f30thn-etched.step` / `sx2m50-000e20f30thn-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sx2m50-000e20f30thn.step` / `sx2m50-000e20f30thn.glb` are the bare package body.
