100 MHz MEMS oscillator with automotive-grade qualification
The DSC1121CE2-100.0000 is a 100 MHz XO (Standard) oscillator built on a MEMS resonator, delivering a CMOS output with ±25ppm frequency stability across its -20°C to 70°C operating range. Rated AEC-Q100, this oscillator is qualified for automotive applications where reliability screening and temperature cycling are required — suitable for infotainment, ADAS camera modules, and body-control ECU clock trees.
Supply voltage flexibility and power management
The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without an external regulator — a single part serves mixed-voltage designs. An Enable/Disable pin (active-high) lets the system gate the oscillator output, dropping supply current from 35 mA max to 22 mA max in the disabled state — useful for sleep-mode power budgets in battery-backed modules.
Package and mounting for production
Housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the DSC1121CE2-100.0000 is a surface-mount component compatible with standard reflow profiles and automated pick-and-place assembly. The MEMS base resonator eliminates the quartz crystal start-up time and vibration sensitivity typical of conventional oscillators — a practical advantage in automotive and industrial environments where mechanical shock is present.
