SSW024000I3CHE-T

HELE Harmony Elec · Crystal Oscillators · SMD3225-4P

SSW024000I3CHE-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 (Vih min Vdd×0.7) gives oscillation output, L (Vil max Vdd×0.3) puts the output in high impedance with Idd2 max 0.01 mA.
2 GND power_in Ground; a 0.01μF ceramic bypass capacitor between Vdd and GND is recommended.
3 Output output C-MOS clock output at 24.000MHz, rated for CL = 15pF, Vol max 0.1×Vdd, Voh min 0.9×Vdd, Iout max 20 mA.
4 Vdd power_in Supply voltage 3.0 to 3.6 V (3.3 V typ), absolute maximum -0.5 to 4.0 V, Idd1 max 10 mA.
