48 MHz MEMS clock, 3.3 V CMOS — what it is
The DSC1033CI1-048.0000 is a 48 MHz MEMS-based oscillator from Microchip's PureSilicon™ series, delivering a CMOS output at 3.3 V with ±50 ppm frequency stability.
4-SMD package and board fit
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 same footprint as many standard quartz oscillators, so a layout designed for a 3.2 x 2.5 mm XO can accept this MEMS part without a board spin. Surface-mount assembly with a standard reflow profile; no special handling beyond normal ESD precautions for a CMOS device.
