SX3M14.7456M20F30TNN 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 | OE/Tri-State | input | Output enable (Tri-State) input: output is enabled when OE is logic 1 (at least 0.7Vdd) or open, and disabled when OE is logic 0 (at most 0.3Vdd). |
| 2 | GND | power_in | Ground connection for the oscillator. |
| 3 | Output | output | CMOS clock output rated for a 15pF load, with VOH of at least 0.9Vdd and VOL of at most 0.1Vdd. |
| 4 | Vdd | power_in | Supply voltage pin, 1.62V to 3.63V. |
