SWOCEV33S8-33.333000 from Starwave(思大), 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 enable input: the oscillator is enabled when high or floating (at least 2.31 V at 3.3 V, 1.75 V at 2.5 V, 1.26 V at 1.8 V) and disabled when low or at GND (no more than 0.99 V at 3.3 V, 0.75 V at 2.5 V, 0.54 V at 1.8 V). |
| 2 | GND | power_in | Ground reference; a 0.1 µF bypass capacitor should be placed as close to the part as possible between VDD and GND pads. |
| 3 | Output | output | Clock output with output high of at least 2.97 V (3.3 V), 2.25 V (2.5 V) or 1.62 V (1.8 V) and output low of at most 0.33 V, 0.25 V or 0.18 V respectively, specified for a 15 pF output load. |
| 4 | VDD | power_in | Supply voltage of 3.3 V, 2.5 V or 1.8 V, with supply voltage variation of VDD-5% to VDD+5%; a 0.1 µF bypass capacitor is recommended between VDD and GND. |
