**Yajingxin** · Crystals · SMD3225-4P

TX322524M4FBCE2T from Yajingxin, 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 (pad 1, marked by the chamfered pad); the connection drawing shows it as one of the two crystal terminals, for a 24.000000 MHz fundamental crystal with 12 pF load capacitance. |
| 2 | GND | power_in | Pad 2 is labelled GND in the Connection Top View drawing (case ground). |
| 3 | XTAL2 | passive | Crystal terminal 2 (pad 3, diagonal to pad 1); the connection drawing shows it as the other crystal terminal, for a 24.000000 MHz fundamental crystal with 12 pF load capacitance. |
| 4 | GND | power_in | Pad 4 is labelled GND in the Connection Top View drawing (case ground). |
