40 MHz MEMS XO with wide supply range
The DSC1001CC1-040.0000 is a 40 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±50ppm frequency stability across the full 1.8V to 3.3V supply range. AEC-Q100 qualification means this oscillator has passed automotive-grade reliability testing — suitable for infotainment, ADAS sensor modules, or body electronics where a quartz crystal would be vulnerable to shock and vibration. The MEMS resonator is inherently more resistant to mechanical stress than a quartz crystal, which matters in automotive and industrial environments where board flex or thermal cycling can shift frequency.
Standby function and power-down current
A standby (power-down) function drops supply current to 15µA max — useful for battery-backed systems that need to disable the clock when the main processor sleeps. Active supply current is 7.2mA max at 40 MHz, typical for a 40 MHz CMOS-output oscillator; the standby current is three orders of magnitude lower, so the power-down pin can extend battery life in intermittently powered applications.
Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — a compact footprint that fits tight PCB layouts without requiring a dedicated oscillator can. Surface-mount assembly with standard reflow profiles; the 4-pad layout is compatible with common oscillator footprints, simplifying a drop-in replacement for quartz-based XOs of the same size.
