SIT1602AI-22-33E-26.000000D

SiTime · Pre-programmed Oscillators · SMD3225-4P

SIT1602AI-22-33E-26.000000D from SiTime, 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/ST input Output Enable (this MPN's "E" option): H or open gives specified frequency output, L puts output in high impedance with only the output driver disabled; ST variant instead puts the output low with weak pull-down and enters sleep mode; VIH min 70% Vdd, VIL max 30% Vdd.
2 GND power_in Electrical ground; a 0.1 µF capacitor between Vdd and GND is recommended.
3 OUT output Oscillator LVCMOS output, specified with a 15 pF load.
4 VDD power_in Power supply voltage (3.3V ±10% for this MPN, 2.97 V to 3.63 V); a 0.1 µF capacitor between Vdd and GND is recommended.
