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. ## Active production – no end-of-life notice","metaTitle":"DSC1033BE1-025.0000T MEMS XO 25 MHz CMOS – Microchip Active","metaDescription":"Active-production MEMS oscillator, 25 MHz, CMOS output, 3.3 V, ±50 ppm, standby power-down, 4-SMD package.

When the enable pin is pulled low (or high, per the logic table in the datasheet), the oscillator stops and the output goes high-impedance. This is designed for systems that need to cut clock power during sleep modes without removing the supply rail."},{"question":"How does the DSC1033BE1-025.0000T compare to a quartz oscillator?","answer":"The MEMS resonator eliminates the quartz crystal's startup time — the DSC1033BE1 reaches stable frequency within microseconds of power-up, versus milliseconds for a typical quartz oscillator. It also avoids the need for external load capacitors and is more resistant to vibration and shock. The trade-off is that quartz parts can offer tighter stability options below ±50 ppm if required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033BE1-025.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033BE1-025.0000T when reusing this data.
