The ±25 ppm frequency stability keeps the clock edge jitter within budget for most MCU and FPGA reference inputs without external trimming. It draws 4 mA typical during operation and drops to 1 µA in standby (power-down) mode, so a battery-powered design can gate the oscillator off between active periods without a separate enable switch. ## MEMS resonator, 4-SMD no-lead package The base resonator is MEMS rather than quartz — this gives faster start-up and better shock/vibration tolerance than a traditional crystal oscillator. The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm, fitting tight layout footprints. ## Active production, quoted to order Microchip lists the DSC1018CE2-040.0000T as Active.","metaTitle":"DSC1018CE2-040.0000T 40 MHz MEMS XO, 1.8V CMOS, ±25 ppm","metaDescription":"Microchip DSC1018CE2-040.0000T: 40 MHz MEMS oscillator, 1.8V supply, CMOS output, ±25 ppm stability, -20°C to 70°C, 4 mA typ.
