C3SB18.432F12M13 from CJKJ, 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 resonator, for 18.432 MHz fundamental operation with 12 pF load capacitance. |
| 2 | GND | power_in | Pad marked GND in the connection drawing, tied to the lid/ground and not connected to the resonator. |
| 3 | XTAL2 | passive | Crystal terminal 2 connected to the other side of the resonator, for 18.432 MHz fundamental operation with 12 pF load capacitance. |
| 4 | GND | power_in | Pad marked GND in the connection drawing, tied to the lid/ground and not connected to the resonator. |
