CN4027M12012001 from huaxindianzi, in a SMD2016-4P. 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 of the 27.120 MHz fundamental AT-cut crystal (CL 12 pF), connected across the crystal blank with pin 3. |
| 2 | GND | power_in | Pad 2 is labelled GND in the top-view crystal connection drawing (lid/case ground). |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 27.120 MHz fundamental AT-cut crystal (CL 12 pF), connected across the crystal blank with pin 1. |
| 4 | GND | power_in | Pad 4 is labelled GND in the top-view crystal connection drawing (lid/case ground). |
