**Interquip** · Oscillators · SMD2520-4P

1651-50005-BTBEYA from Interquip, in a SMD2520-4P. 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 output; the datasheet states no logic thresholds. |
| 2 | GND | power_in | Ground connection of the oscillator. |
| 3 | Output | output | CMOS clock output with VOH 90% VDD and VOL 10% VDD, specified for a 15pF load. |
| 4 | VDD | power_in | Positive supply input, specified for 1.0V to 5V supply voltage range. |
