7U16000E16UCG from SJK SHENZHEN CRYSTAL TECH, 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 (pin 1 has the chamfered pad marker), connected to one side of the 16.000MHz AT-cut fundamental crystal with 16pF load capacitance. |
| 2 | GND | power_in | Marked GND in the top-view crystal connection drawing; connected to ground (lid/case ground). |
| 3 | XTAL2 | passive | Crystal terminal 2, connected to the other side of the 16.000MHz AT-cut fundamental crystal with 16pF load capacitance. |
| 4 | GND | power_in | Marked GND in the top-view crystal connection drawing; connected to ground (lid/case ground). |
