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

ATX-12-F-26.000MHZ-F05-T 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 | GND | power_in | Ground connection listed as pin 1 in the pin function table; the datasheet states no separate electrical limit for this pin. |
| 2 | GND | power_in | Ground connection listed as pin 2 in the pin function table; the datasheet states no separate electrical limit for this pin. |
| 3 | Output | output | Clipped sine wave output of 0.8 Vp-p into 10 kΩ ||10 pF load, requiring an external DC-cut capacitor (1000 pF recommended). |
| 4 | Vdd | power_in | Supply voltage; for Option F (the code in this MPN) the datasheet specifies +1.68 V to +3.63 V. |
