**Abracon LLC** · Oscillators · SMD3225-4P

ASE3-25.000MHZ-LC-T from Abracon LLC, 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 | Tristate | input | Tristate function: logic "1" (VIH ≥ 0.7*Vdd) or open gives oscillation, and logic "0" (VIL < 0.3*Vdd) puts the output in Hi Z. |
| 2 | GND/Case | power_in | Ground pin, also connected to the case. |
| 3 | Output | output | Clock output with output level VOH of 0.9*Vdd and VOL of 0.1*Vdd as stated in the electrical table. |
| 4 | Vdd | power_in | Supply voltage pin, specified at +1.71 V minimum, +1.80 V typical and +1.89 V maximum. |
