ASEMB-12.000MHZ-LC-T

Abracon LLC · Global Sourcing Parts · SMD3225-4P

ASEMB-12.000MHZ-LC-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 Standby input Tri-state/standby control: logic 1 (VIH 0.7Vdd) or open enables oscillation, logic 0 (VIL<0.25Vdd) puts the output in Hi-Z.
2 GND power_in Ground; a bypass capacitor of approximately 0.01uF is recommended between pin 2 and pin 4.
3 Output output Clock output, rated for 15, 25 or 40pF load depending on option, with 45-55% symmetry at 1/2Vdd.
4 VDD power_in Supply voltage pin, +1.8V to +3.3V nominal (absolute max -0.3V to +4.0V); bypass with about 0.01uF to pin 2.
