125 MHz DSC400 Oscillators 3 Oscillators MEMS-Based Oscillators Microchip has developed unique MEMS-based oscillators that replace traditional quartz solutions. A micrometer-sized polysilicon MEMS resonator is packaged with a CMOS oscillator ASIC, yielding a single-package integrated solution. Our MEMS-based timing products are ultra-small with exceptional shock resistance, due to the ultra miniature resonator. They also operate with excellent frequency stability over extended temperature ranges. They are an ideal choice in demanding environments where high reliability is key, and performance must be maintained at temperature extremes—such as automotive and many consumer/industrial applications. 60 50 40 30 20 10 0 −10 Microchip’s MEMS LVPECL 156.25 MHz Competitor 1 Competitor 2 Competitor 3 −40 −30 −20 −10 0 10 20 30 40 50 60 70 80 90 100 110 120 130 Temperature (°C) Frequency Deviation (ppm) Voltage Regulator PIC® Microcontroller LIN Transceiver LIN CAN Transceiver CAN SPI/I2C Body Controller EEPROM DSC1101 48 MHz clock to image processor Image Processor Imager Control Camera In-Vehicle Display NTSC/PAL VBAT High Stability Over Extended Temperature Automotive Camera Application, Using the MEMS DSC1101 Oscillator Quartz-Based Oscillators Microchip’s quartz-based oscillators are available in single-package fully integrated solutions. Our assembly process physically isolates the crystal blank from other components, and preserves crystal aging stability and reliability. The oscillator ASIC includes a very low-noise phase lock loop and one or more output buffers, achieving programmability in frequency, output format and OE options. Ultra-low phase jitter at 100 fs and less makes the MX series of products a perfect choice for demanding high-speed telecommunication/networking applications.
