HD · Crystals · SMD3225-4P
7B028375R01 from HD, 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 | CRYSTAL | passive | Crystal terminal connected to one side of the 28.375MHz quartz resonator (20pF load capacitance, 100μW max drive level). |
| 2 | GND | power_in | Ground pad, shown as GND in the internal view connection and not connected to the crystal element. |
| 3 | CRYSTAL | passive | Crystal terminal connected to the other side of the 28.375MHz quartz resonator (20pF load capacitance, 100μW max drive level). |
| 4 | GND | power_in | Ground pad, shown as GND in the internal view connection and not connected to the crystal element. |
