ASTX-H12-12.000MHZ-T

Abracon LLC · Pre-ordered Products · SMD2520-4P

ASTX-H12-12.000MHZ-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 Tri-state tri_state Tri-state control: logic 1 (VIH ≥ 0.75Vdd) or open keeps the output oscillating, while logic 0 (VIL < 0.25Vdd) puts the output in Hi-Z.
2 GND power_in Ground reference pin; datasheet recommends an approximately 0.01µF bypass capacitor between Pin 2 and Pin 4.
3 Output output HCMOS clock output with 5 ns maximum rise/fall time (10%-90% Vdd), 45-55% symmetry at 1/2 Vdd, and 15 pF load.
4 Vdd power_in Supply voltage input of 2.97 V to 3.63 V (3.3 V nominal) for the standard option; recommended bypass capacitor of approximately 0.01µF to Pin 2.
