DSC8002

DSC8002 Series 1.8 to 3.3V Programmable Low-Power CMOS Oscillator General Description The DSC8002 is a programmable MEMS based PureSilicon™ Oscillator. Using the DragonFly™ or TimeFlash™ handheld programmer, the end user can program the DSC8002 within seconds to any frequency from 1 to 150MHz in increments of 100Hz (up to four decimal point resolution). The nominal operational range spans from 1.8 to 3.3 Volts, without any need for additional external components, providing ease of use and flexibility in multi-voltage applications. The DSC8002 incorporates an all silicon resonator that is extremely robust and nearly immune to stress related fractures, common to crystal based oscillators. Without sacrificing the performance and stability required of today’s systems, a crystal-less design allows for a higher level of reliability, making the DSC8002 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. Available in industry standard packages, the DSC8002 can be “dropped-in” to the same PCB footprint as standard crystal oscillators.
