1C218432CC0E 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 | XTAL1 | passive | Crystal terminal for the 18.432 MHz fundamental-mode DSX321G crystal, load capacitance CL 10.0 pF, drive level 10 uW +/- 2 uW. |
| 2 | GND | power_in | Pin #2 is either not connected with anything or must be connected with GND, depending on the variant; the text shows both statements. |
| 3 | XTAL2 | passive | Second crystal terminal for the 18.432 MHz fundamental-mode DSX321G crystal, series resistance 80 ohms max. |
| 4 | GND | power_in | Pin #4 is either not connected with anything or must be connected with GND, depending on the variant; the text shows both statements. |
