The Abracon ASEMPA series is a programmable MEMS oscillator, with a continuous

operating power supply ranging from 2.25V to 3.63V. This series features low power

consumption, a wide frequency range, exceptional phase noise, tight stabilities, and short

lead times for industrial, consumer, and other applications. The ASEMPA series comes

in a 3.2 x 2.5 mm compact package with CMOS, HCSL, LVDS, or LVPECL output logic.
