What this MEMS oscillator replaces and why
A standard quartz XO at 27 MHz might meet the frequency spec but lacks the AEC-Q100 qualification and MEMS shock/vibration tolerance this part carries — the DSC6003MI2B-027.0000 is a drop-in CMOS-output replacement for quartz oscillators in automotive and industrial designs where reliability under temperature cycling and mechanical stress is non-negotiable.
Supply voltage and output compatibility
The 1.71V to 3.63V supply range means this oscillator works across 1.8V, 2.5V, and 3.3V logic rails without a separate level translator — the CMOS output drives the clock input of the downstream SoC or FPGA directly. With a typical supply current of 1.3 mA max, the power budget impact is negligible — useful for battery-powered or thermally constrained enclosures.
Package footprint and board layout
Housed in a 4-VFLGA package measuring 2.00 mm x 1.60 mm with a seated height of 0.89 mm, this is a compact surface-mount device — the 0.50 mm pitch pads require careful solder-paste stencil design to avoid bridging, but the small footprint frees board area for other components.
