# NX3225GA-20MHZ-STD-CRA-1

**NDK** · Crystals · SMD3225-4P

NX3225GA-20MHZ-STD-CRA-1 from NDK, 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 connected to the resonator; the datasheet shows it as a terminal land on the top view without naming it. |
| 2 | NC | unconnected | Not connected internally; the datasheet recommends connecting it to GND, but leaving it NC is also possible. |
| 3 | XTAL2 | passive | Crystal terminal connected to the resonator; the datasheet shows it as a terminal land on the top view without naming it. |
| 4 | NC | unconnected | Not connected internally; the datasheet recommends connecting it to GND, but leaving it NC is also possible. |

## CAD (KiCad official)

- Symbol: `NX3225GA-20MHZ-STD-CRA-1`
- Footprint: `Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm`
- 3D model: SMD3225-4P (KiCad packages3D, STEP)
- 3D model files: `nx3225ga-20mhz-std-cra-1-etched.step` / `nx3225ga-20mhz-std-cra-1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `nx3225ga-20mhz-std-cra-1.step` / `nx3225ga-20mhz-std-cra-1.glb` are the bare package body.
