The MEMS die is inherently more shock- and vibration-tolerant than a quartz blank, and it starts up without the settling time a crystal needs — the output is valid within microseconds of power being applied. The Enable/Disable pin lets the system gate the output; when disabled the supply current drops from 35 mA to 22 mA, which matters for battery-powered equipment that sleeps between bursts. ## Temperature grade and deployment fit The ±10 ppm frequency stability holds the clock edge jitter within the timing budget for a 125 MHz SERDES or a high-speed ADC sample clock. ## Package and board-fit note The 6-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits on densely populated boards. Surface-mount assembly with standard reflow profiles; no special handling beyond the usual ESD precautions for CMOS devices.","metaTitle":"DSC1121CL5-125.0000T MEMS Oscillator 125 MHz CMOS Active","metaDescription":"Microchip DSC1121CL5-125.0000T XO, 125 MHz CMOS output, MEMS resonator, 2.25-3.6V supply, -40 to 105°C, Enable/Disable.
