100 MHz MEMS oscillator with AEC-Q100 qualification
The DSC1001DE1-100.0000T is a 100 MHz MEMS-based XO (Standard) from the Microchip DSC1001 series, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range. Rated AEC-Q100, this oscillator is qualified for automotive applications — the MEMS resonator and CMOS output stage are tested to the reliability stress and temperature cycling requirements of that standard.
Standby power-down and supply flexibility
A standby (power-down) function drops the supply current to 15 µA max when disabled — useful for gating the clock tree in battery-backed or intermittent-operation systems. The supply range spans 1.8 V to 3.3 V, so the same part can be shared across 1.8 V and 3.3 V logic domains without a separate level translator on the oscillator output.
Package and mounting footprint
Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm max — a compact footprint that fits tight clock-tree layouts on multi-layer boards. The MEMS base resonator eliminates the quartz crystal start-up time and vibration sensitivity typical of conventional oscillators, though the package still requires standard reflow soldering with no special handling beyond MSL precautions.
