SIT2001BI-S2-25N-3.000000

SiTime · Pre-programmed Oscillators · SOT-23-5

SIT2001BI-S2-25N-3.000000 from SiTime, in a SOT-23-5. 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 GND power_in Electrical ground.
2 NC unconnected No connect pin.
3 OE/ST/NC unconnected In the NC option (ordering code N, as in this MPN) pin 3 has no function and any voltage between 0 and Vdd or open gives the specified frequency output.
4 VDD power_in Power supply voltage (2.25 V to 2.75 V for the 2.5 V option); a 0.1 µF or larger capacitor between Vdd and GND is required.
5 OUT output LVCMOS oscillator output.
