SiT8008AI-22-33E-8.000000D

SiTime · Programmable Oscillators · SMD3225-4P

SiT8008AI-22-33E-8.000000D 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 pin (this MPN carries feature code E, so OE mode applies): high or open gives the specified frequency output, while low puts OUT in high impedance by disabling only the output driver, with input high at 70% Vdd minimum and input low at 30% Vdd maximum.
2 GND power_in Electrical ground, and a 0.1 µF capacitor between Vdd and GND is recommended.
3 OUT output Oscillator LVCMOS/HCMOS-compatible clock output.
4 VDD power_in Power supply voltage, with absolute maximum rating of -0.5 V to 4 V and a 2.97 V to 3.63 V operating range for the 3.3 V option (code 33) of this MPN.
