# 83020000301

**HD** · Crystal Oscillators · SMD3225-4P

83020000301 from HD, 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 | NC | unconnected | No connection; the pin table lists this pad as NC (the datasheet also lists output enable/disable control as a feature but does not assign it to a pin). |
| 2 | GND | power_in | Ground; place a 0.1uF by-pass capacitor as close as possible between the VDD and GND pads. |
| 3 | Output | output | CMOS clock output at 20.000MHz with 15pF load, 8ns max rise/fall time and 50±10% symmetry. |
| 4 | VDD | power_in | Supply voltage input of +3.3Vdc±10%, 20mA max supply current; place a 0.1uF by-pass capacitor to GND. |
