The DSC63xx family of products from Microchip Technology are ultra-small and ultra-low-power spread-spectrum MEMS oscillators. They are available in four package sizes with operation as low as 3 mA; the smallest 4-pin package is a mere 1.6 mm x 1.2 mm in size. The devices support up to ±2.5% or -3% spread spectrum that can achieve up to 15 dB electro-magnetic interference (EMI) reduction on fundamental frequency (more on high harmonics). Because of industry standard package and pin options, customers can solve last-minute EMI problems simply by putting the DSC6300 on their current board layout with no redesign required. The DSC63xx family is available in ultra-small 1.6 mm x 1.2 mm and 2.0 mm x 1.6 mm packages. Other package sizes include 2.5 mm x 2.0 mm and 3.2 mm x 2.5 mm. These packages are "drop-in" replacements for standard 4-pin CMOS quartz crystals. The rich feature set and small physical size make these parts suitable for everything from industrial, harsh environment applications to battery-powered, mobile, wearables, and IoT.
