L327S27BU11L from Lucki, 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 (marked pad with chamfered corner) of the 27.1383 MHz, 20 pF fundamental crystal, connected to one side of the resonator per the connection drawing. |
| 2 | GND | power_in | Ground pad, labeled GND in the connection drawing, tied to the metal lid and not connected to the crystal terminals. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 27.1383 MHz, 20 pF fundamental crystal, connected to the other side of the resonator per the connection drawing. |
| 4 | GND | power_in | Ground pad, labeled GND in the connection drawing, tied to the metal lid and not connected to the crystal terminals. |
