**Starwave(思大)** · IC · SMD3225-4P

LCOCEVXXS8-4.000000 from Starwave(思大), 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 | Tri-state | tri_state | Tri-state control pad: high or open keeps normal oscillation, while low puts the output in high impedance and stops oscillation. |
| 2 | GND | power_in | Ground reference pin for the oscillator. |
| 3 | Output | output | CMOS clock output, with the load CL and levels given in the electrical specifications. |
| 4 | VDD | power_in | Supply voltage pin, specified at 1.8 to 3.3 V ±10%. |
