The DSC1004CI2-054.0000 is a 54 MHz MEMS-based oscillator (XO) with CMOS output, part of Microchip's DSC1004 series.
Supply range, standby power, and package footprint
Supply voltage covers 1.8V to 3.3V, so the same BOM line works across 1.8V, 2.5V, or 3.3V digital rails — no voltage-level translator needed at the oscillator output. Active supply current is 8 mA max. Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the 0.50 mm pitch pads require a solder-paste stencil aperture matched to the land pattern for consistent fillet formation.
