CJO05-080003320B30 from Changjing, 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 | Enable/Disable | input | Output enable: high (>=0.7VDD) or open gives normal oscillation, low (<=0.3VDD) stops the oscillator and puts output (Pin 3) in high impedance. |
| 2 | GND | power_in | Ground connection. |
| 3 | Output | output | CMOS clock output at 8MHz, 15pF load, goes high impedance when Pin 1 is low. |
| 4 | VDD | power_in | Supply voltage input, +3.3Vdc ±10%. |
