# ATX-H11-F-25.000MHZ-F25-T

**Abracon LLC** · Temperature Compensated Crystal Oscillators (TCXOs) · SMD3225-4P

ATX-H11-F-25.000MHZ-F25-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 | INH | input | Tri-state enable: open or logic 1 (VIH ≥0.7*Vdd) gives oscillation, while logic 0 (VIL <0.3*Vdd) stops oscillation with output high-Z; pin 1 must not be left floating and should be tied to Vdd if not used for toggling. |
| 2 | GND | power_in | Ground reference; recommended to use approximately 0.01µF bypass capacitor between pin 2 and pin 4. |
| 3 | Output | output | CMOS clock output into 15 pF load, with rise and fall time of 5 ns between 10% and 90% of Vdd. |
| 4 | Vdd | power_in | Supply voltage; option F range is +1.68 V to +3.63 V, and recommended bypass is approximately 0.01µF to pin 2. |
