ASD1-50.000MHZ-EC-T

Abracon LLC · Crystal Oscillators · SMD2520-4P

ASD1-50.000MHZ-EC-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 input Standby control: logic "1" (VIH ≥ 0.7Vdd) or open enables oscillation, while logic "0" (VIH < 0.3Vdd) stops oscillation and puts the output in Hi-Z.
2 GND/Case power_in Ground connection, also tied to the metal case of the package.
3 Output output HCMOS clock output, specified with a 15 pF CMOS load, with VOH of 0.9Vdd and VOL of 0.1Vdd.
4 Vdd power_in Supply pin; for the ASD1 (3.0 V) variant the supply is +3.0 V nominal with a 2.85 V to 3.15 V range, and Abracon recommends an approximately 0.01 µF bypass capacitor between pins 2 and 4.
