**SST** · Crystals · SMD3225-4P

3225 24M 12PF 10PPM from SST, 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 | XTAL1 | passive | Crystal terminal 1 connected to one side of the 24.000MHz resonator (12pF load capacitance, ESR ≤60Ω); pin 1 is the pad with the chamfered corner. |
| 2 | GND | power_in | Ground connection pad, marked GND in the connection diagram (typically tied to the lid/case). |
| 3 | XTAL2 | passive | Crystal terminal 2 connected to the other side of the 24.000MHz resonator (12pF load capacitance, ESR ≤60Ω). |
| 4 | GND | power_in | Ground connection pad, marked GND in the connection diagram (typically tied to the lid/case). |
