# SX3M20.000E20F30TJN

**Shenzhen SCTF Elec** · Crystal Oscillators · SMD3225-4P

SX3M20.000E20F30TJN from Shenzhen SCTF Elec, in a SMD3225-4P. 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 (OE): output is enabled when Logic 1 (VIH min 0.7Vdd) or open, and disabled when Logic 0 (VIL max 0.3Vdd); connected to GND the product stops working. |
| 2 | GND | power_in | Ground connection. |
| 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 input, 0.8V to 2.0V (1.2V typ.). |

## CAD (KiCad official)

- Symbol: `SX3M20.000E20F30TJN`
- Footprint: `Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm`
- 3D model: SMD3225-4P (KiCad packages3D, STEP)
- 3D model files: `sx3m20-000e20f30tjn-etched.step` / `sx3m20-000e20f30tjn-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sx3m20-000e20f30tjn.step` / `sx3m20-000e20f30tjn.glb` are the bare package body.
