SSW050000I3CHE-T

HELE(Harmony Elec) · Oscillators · SMD3225-4P

SSW050000I3CHE-T from HELE(Harmony Elec), 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 OE input Output Enable: open or "H" gives oscillation output, "L" level puts the output in High-Z (Idd2 max 0.01 mA); Vil max Vdd x0.3, Vih min Vdd x0.7.
2 GND power_in Ground; a 0.01 uF ceramic bypass capacitor between Vdd and GND is recommended.
3 Output output C-MOS oscillation output at 50.000 MHz, CL = 15 pF, Voh min 0.9xVdd, Vol max 0.1xVdd, High-Z when OE is "L".
4 Vdd power_in Supply voltage 3.0 V to 3.6 V (3.3 V typ), absolute maximum -0.5 to 4.0 V.
