7Q16300001 from TXC Corp, 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 | GND or NC | power_in | The pin function table lists pin 1 as "GND or NC", so it may be tied to ground or left unconnected; the datasheet does not give further limits for it. |
| 2 | GND | power_in | Ground connection listed in the pin function table and shown as GND in the testing circuit. |
| 3 | OUTPUT | output | Clipped sinewave output (typically 0.8 V output level), specified with load 10 kΩ // 10 pF ±10% and a DC blocking capacitor C2 (1000 pF) on the output. |
| 4 | VCC | power_in | Supply pin, Vcc 2.8 V ±5%, with an AC noise bypass capacitor C1 (10 nF) to be placed on VCC and a decoupling capacitor required in the external circuit. |
