X32258MOB4SI from Yangxing 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 of the 8 MHz fundamental AT-cut unit (CL 12 pF, ESR max 150 Ω, drive level 100 µW), pin 1 marked by the chamfered pad. |
| 2 | GND | power_in | Ground pin, labelled GND in the datasheet's crystal connection top view, not part of the resonator. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 8 MHz fundamental AT-cut unit (CL 12 pF, ESR max 150 Ω, drive level 100 µW), diagonal to pin 1. |
| 4 | GND | power_in | Ground pin, labelled GND in the datasheet's crystal connection top view, not part of the resonator. |
