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

S3D40.000000B20F30T 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 enable: connecting pin 1 to Vdd or leaving it floating keeps the oscillator working, while connecting it to GND stops the output. |
| 2 | GND | power_in | Ground reference for the oscillator supply. |
| 3 | Output | output | Clock output with a rated load of 15pF HCMOS or 10 TTL, with rise/fall time of 5 ns max. |
| 4 | Vdd | power_in | Supply voltage of 5.0V or 3.3V ±10% (1.8V, 2.5V and 2.85V can be made on customer request). |
