# 7V25070001

**TXC Corp** · Crystals · SMD3225-4P

7V25070001 from TXC Corp, 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 (pad 1, marked with the chamfered pad in the bottom view); diagonal to pad 3. |
| 2 | NC | unconnected | Not connected; the suggested connection drawing marks pad 2 as NC. |
| 3 | XTAL2 | passive | Crystal terminal connected to the resonator (pad 3), the second crystal terminal diagonal to pad 1. |
| 4 | NC | unconnected | Not connected; the suggested connection drawing marks pad 4 as NC. |
