KDS Daishinku · Crystals · SMD3225-4P
DSX321G 12MHz from KDS Daishinku, 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 terminal (#1) | passive | Crystal terminal #1 of the resonator; the datasheet identifies #1 and #3 as the crystal terminals and gives no separate electrical limit for this pin. |
| 2 | Open (#2) | unconnected | Pin #2 is open (not connected) per the datasheet and should be left unconnected. |
| 3 | Crystal terminal (#3) | passive | Crystal terminal #3 of the resonator; the datasheet identifies #1 and #3 as the crystal terminals and gives no separate electrical limit for this pin. |
| 4 | Open (#4) | unconnected | Pin #4 is open (not connected) per the datasheet and should be left unconnected. |
