The DSC1033BI2-027.1200T is a MEMS-based oscillator (XO) from Microchip's PureSilicon™ series, delivering a 27.12 MHz CMOS clock from a 3.3 V supply in a 5.0 × 3.2 mm 4-SMD package.
Microchip lists the DSC1033BI2-027.1200T as Obsolete. For new designs, consider the active DSC1033 series variants at the same frequency and stability grade — confirm the package and pinout match before committing the layout.
4-SMD, No Lead package, 5.00 × 3.20 mm footprint, 0.90 mm seated height. The MEMS die and ASIC are encapsulated — no quartz crystal means no start-up trade-off and better shock tolerance.
