DSC8004CI2-PROGRAMMABLE

DSC8004 Series 1.8~3.3V Programmable Low-Power Precision CMOS Oscillator General Description Features The DSC8004 is a programmable silicon MEMS based CMOS oscillator offering excellent jitter and stability performance over a wide range of supply voltages and temperatures. The device operates from 1 to 150MHz in increments of 100Hz (up to four decimal point resolution) with supply voltages between 1.8 to 3.3 Volts and extended temperatures from -40ºC to 105ºC. The DSC8004 has the same functionality and performance as the DSC8001 but with greater output drive (CL=40pf). The DSC8004 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 DSC8004 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. Available in industry standard packages, the DSC8004 can be “dropped-in” to the same PCB footprint as standard crystal oscillators.         Benefits   Block Diagram VDD Output Frequency Range: Programmable from 1 to 150MHz Exceptional Stability over Temperature o ±20 PPM , ±25 PPM, ±50 PPM Operating voltage o 1.71 to 3.60V Operating Temperature Range o Ext.
