SIT8103AI-22-33E-3.57000T 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 or standby control (per feature pin option); H or open gives specified frequency output, L gives high impedance (OE) or low level with oscillation stopped (ST), VIH min 70% Vdd and VIL max 30% Vdd. |
| 2 | GND | power_in | Power supply ground. |
| 3 | CLK | output | LVCMOS/LVTTL clock output, specified for a maximum 15 pF load. |
| 4 | VDD | power_in | Power supply voltage (1.71-1.89 V, 2.25-2.75 V, 2.52-3.08 V or 2.97-3.63 V depending on option); a 0.1 μF capacitor between Vdd and GND is recommended. |
