**YXC** · Crystals · SMD3225-4P

XL2RI-111-24M from YXC, 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 3.20x2.50 mm AT-fundamental unit, connected across the crystal to pin 3; load capacitance 10pF or 20pF. |
| 2 | GND | power_in | Ground connection (#2) per the Top View Crystal Connection drawing, labeled GND. |
| 3 | XTAL2 | passive | Crystal terminal (#3) connected across the crystal to pin 1, opposite diagonal corner. |
| 4 | GND | power_in | Ground connection (#4) per the Top View Crystal Connection drawing, labeled GND. |
