# ASTX-H11-12.000MHZ-T

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

ASTX-H11-12.000MHZ-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 | input | Standby/tri-state control: logic "1" (VIH ≥ 0.75*Vdd) or open enables oscillation, and logic "0" (VIL < 0.25*Vdd) puts the output in Hi-Z. |
| 2 | GND | power_in | Ground return; the datasheet recommends an approximately 0.01µF bypass capacitor between Pin 2 and Pin 4. |
| 3 | Output | output | HCMOS clock output that is active when the tri-state pin is high or floating and high-impedance when it is low, with 5 ns maximum rise/fall time (10%-90% Vdd), 45-55% symmetry at 1/2 Vdd, VOH 90% Vdd, VOL 10% Vdd, and a 15 pF load. |
| 4 | Vdd | power_in | Supply voltage of 2.97 V minimum, 3.3 V typical and 3.63 V maximum (3.3 V ±10%); bypass with approximately 0.01µF to Pin 2. |
