XOS20050000LT00351005 from TOGNJING, in a SMD2016-4P. 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 control: Vdd×0.7 min enables the output (active), Vdd×0.3 max puts the output in the high-impedance state. |
| 2 | GND | power_in | Ground connection. |
| 3 | Output | output | Oscillator clock output, 1 to 125 MHz, with logic high of 0.9Vdd min and logic low of 0.1Vdd max. |
| 4 | Vdd | power_in | Supply voltage, 1.8V, 3.3V or 5V (customizable). |
