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

ASEMB-25.000MHZ-LY-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 | Standby | input | Tri-state/standby control: logic 1 (VIH 0.7*Vdd) or open enables oscillation, logic 0 (VIL<0.25*Vdd) puts the output in Hi-Z. |
| 2 | GND | power_in | Ground; a bypass capacitor of approximately 0.01uF is recommended between pin 2 and pin 4. |
| 3 | Output | output | Clock output, 1.0 to 150 MHz, with 15, 25 or 40 pF load options and 45-55% symmetry. |
| 4 | VDD | power_in | Supply voltage pin, +1.8 to +3.3 V (absolute maximum 4.0 V); bypass with approximately 0.01uF to pin 2. |
