The DSC6001CI2A-040.0000T is a 40 MHz MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering a CMOS output with enable/disable function in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm. Rated for -40°C to +85°C with ±25 ppm frequency stability and a typical supply current of 1.3 mA, it suits industrial and automotive environments where a quartz crystal would need external load capacitors and a separate oscillator circuit. AEC-Q100 qualification confirms it meets automotive stress and reliability requirements — suitable for under-hood or cabin-domain ECUs that must survive temperature cycling and vibration.
Operates from a 1.71V to 3.63V supply rail, covering 1.8V, 2.5V, and 3.3V logic domains without an external level translator — the enable/disable pin lets a microcontroller gate the output for power savings in multi-clock designs.
