O32253579545MEDA4SC-1 from YXC Crystal Oscillators, 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 | E/D | input | Tri-state enable/disable control (三态/无三态); the datasheet states a tri-state function is available, but the active logic level is not given in the text. |
| 2 | GND | power_in | Ground (接地) connection for the oscillator. |
| 3 | OUTPUT | output | CMOS clock output with 15pF load, 90%Vdd min / 10%Vdd max levels, 40-60% symmetry, and 8 ns max rise/fall time. |
| 4 | Vdd | power_in | Supply voltage (电源电压); the datasheet lists 1.8V, 2.5V, 3.3V or 5V options, with 3.3V and 5V/1.8V variants defined in the part number guide. |
