7Q32000I33ZF from SJK(SHENZHEN CRYSTAL TECH), 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 | AFC/GND | passive | Pin 1 connects to AFC (voltage control) or GND; the 7Q32000I33ZF measurement circuit shows #1 tied to GND. |
| 2 | GND | power_in | Ground connection, tied to supply negative in the measurement circuit. |
| 3 | OUTPUT | output | Clipped sine wave output, 0.8 to 2 Vp-p into a 10 kOhm / 10 pF load. |
| 4 | VCC | power_in | Supply voltage pin, 3.135 V to 3.465 V (3.3 V typ), with a maximum current drain of 2 mA. |
