**Interquip** · Oscillators · SMD2016-4P

1681-24005-BTBEYA from Interquip, 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 | Enable/Disable | input | Enable/Disable control input of the oscillator; the datasheet does not state its logic polarity or threshold. |
| 2 | GND | power_in | Ground connection for the oscillator. |
| 3 | Output | output | CMOS clock output rated for a 15pF load, 45%~55% symmetry, VOH 90% VDD and VOL 10% VDD. |
| 4 | VDD | power_in | Supply voltage pin, 1.0V to 3.3V operating range. |

## CAD (KiCad official)

- Symbol: `1681-24005-BTBEYA`
- Footprint: `Crystal:Crystal_SMD_2016-4Pin_2.0x1.6mm`
- 3D model: SMD2016-4P (KiCad packages3D, STEP)
- 3D model files: `1681-24005-btbeya-etched.step` / `1681-24005-btbeya-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `1681-24005-btbeya.step` / `1681-24005-btbeya.glb` are the bare package body.
