CJO05-500003320B30

Changjing · Crystal Oscillators · SMD3225-4P

CJO05-500003320B30 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 Pin3 in high impedance.
2 GND power_in Ground connection.
3 Output output CMOS clock output at 50MHz, 15pF load, high impedance when Pin1 is low.
4 VDD power_in Supply voltage input, +3.3Vdc±10%, 10mA max supply current.
