# ATXAIG-H12-F-25.000MHZ-F25-T3

**Abracon LLC** · Temperature Compensated Crystal Oscillators (TCXO) · SMD2520-4P

ATXAIG-H12-F-25.000MHZ-F25-T3 from Abracon LLC, in a SMD2520-4P. 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 | INH | input | Inhibit/tri-state control: open or high (VIH≥0.7*Vdd) gives active oscillation, low (VIL<0.3*Vdd) gives High-Z with no oscillation; must not float and must be tied to Vdd if unused. |
| 2 | GND | power_in | Ground; a ~0.01µF bypass capacitor is recommended between pin 2 and pin 4. |
| 3 | Output | output | CMOS clock output, 15 pF load, high-Z when INH is low. |
| 4 | Vdd | power_in | Supply voltage; 3.3V ±5% for Option E, with a ~0.01µF bypass capacitor to GND recommended. |
