HSO321S 12MHZ 3.3V -40~+85℃ 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 x 0.7) gives oscillation output, L (Vil max Vdd x 0.3) puts the output in high impedance and cuts supply current to 0.01 mA max. |
| 2 | GND | power_in | Ground connection. |
| 3 | Output | output | CMOS clock output of 12.000000 MHz, rated for CL = 15 pF, with Voh min 0.9xVdd, Vol max 0.1xVdd and 40-60% duty. |
| 4 | Vdd | power_in | Supply voltage 3.0 to 3.6 V (3.3 V typical), absolute maximum -0.5 to 4.0 V. |
