# ASE-27.000MHZ-LC-T

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

ASE-27.000MHZ-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 | Tri-State (STBY) | input | Tri-state/standby control: logic 1 (VIH≥0.7*Vdd) or open gives oscillation, logic 0 (VIL<0.3*Vdd) gives no oscillation/Hi-Z output, with stand-by current of 10 µA max. |
| 2 | GND/Case | power_in | Ground and case connection; a ~0.01uF bypass capacitor is recommended between pin 2 and pin 4. |
| 3 | Output | output | CMOS clock output driving a 15 pF load with VOH of 0.9*Vdd and VOL of 0.1*Vdd, going Hi-Z when standby is active. |
| 4 | Vdd | power_in | Supply voltage pin, 3.3 V nominal (3.135 V to 3.465 V); a ~0.01uF bypass capacitor is recommended between pin 2 and pin 4. |
