MEMS oscillator at 25 MHz – 3.3 V CMOS output
The DSC1033BE1-025.0000T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 25 MHz CMOS output from a 3.3 V supply rail.
Standby power-down – 1 µA disable current
For a battery-operated sensor node or a controller that spends most of its life asleep, that disable current is below the leakage of a typical coin cell — the oscillator draws essentially nothing until the system wakes it. When enabled, the typical active current is 3 mA maximum at 25 MHz. That 3 mA figure includes the internal MEMS resonator and the CMOS output buffer driving a standard load — no external load caps or bias resistors are needed, unlike a quartz-based oscillator.
Surface-mount 4-SMD package – 5.0 × 3.2 mm footprint
The 4-SMD, No Lead package measures 5.00 mm × 3.20 mm with a seated height of 0.90 mm — a standard footprint shared by many MEMS and quartz oscillators. The land pattern matches industry-standard 4-pad layouts, so the DSC1033BE1-025.0000T can be placed on existing boards without a layout change.
