C3SB13.523F12M13 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 connected to one side of the resonator (13.523130 MHz, CL 12 pF), per the connection diagram on page 4. |
| 2 | GND | power_in | Ground pad marked GND in the connection diagram, not connected to the resonator terminals. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the resonator (13.523130 MHz, CL 12 pF), per the connection diagram on page 4. |
| 4 | GND | power_in | Ground pad marked GND in the connection diagram, not connected to the resonator terminals. |
