ASD-50.000MHZ-LC-T

Abracon LLC · Crystal Oscillators · SMD2520-4P

ASD-50.000MHZ-LC-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 Tri-state standby control: logic '1' (VIH ≥ 0.7Vdd) or open gives oscillation, while logic '0' (VIH < 0.3Vdd) stops oscillation and puts the output in Hi-Z.
2 GND/Case power_in Ground pin, also connected to the metal case; a 0.01 µF bypass capacitor is recommended between pins 2 and 4.
3 Output output HCMOS clock output, specified at 15 pF CMOS load with VOH of 0.9Vdd minimum and VOL of 0.1Vdd maximum.
4 Vdd power_in Supply voltage input; for the blank (3.3 V) Vdd code the supply is 3.3 V ±5% (3.135 V to 3.465 V).
