DSC1004 Low-Power Precision CMOS Oscillators

Microchip Technology DSC1004 Low-Power Precision CMOS Oscillators are silicon MEMS-based CMOS oscillators. These oscillators offer excellent jitter and stability performance over a wide range of supply voltages and temperatures. Each device operates from 1MHz to 150MHz with supply voltages between 1.8V to 3.3V and extended temperatures from -40ºC to +105ºC. The DSC1004 has the same functionality and performance as the DSC1001 but with a greater output drive (CL< 40pf). The DSC1004 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. This feature makes these oscillators ideal for rugged, industrial, and portable applications where stress, shock, and vibration damage quartz crystal-based systems.
