**Starwave** · Pre-Programmed Oscillators · SMD3225-4P

SWPCBV33EF-74.250000D from Starwave, 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 | Tri-state | input | Tri-state output enable/disable input; output enabled at 0.7 x VDD minimum and disabled at 0.3 x VDD maximum. |
| 2 | GND | power_in | Ground; place a 0.1 µF bypass capacitor as close as possible between VDD and GND pads. |
| 3 | Output | output | Oscillator clock output rated for 15 pF load, with 90% VDD minimum output high and 10% VDD maximum output low. |
| 4 | VDD | power_in | Supply voltage pin, 3.3V nominal for this part (VDD-5% to VDD+5% in the electrical table), with 35 mA maximum supply current at 15 pF load. |
