The 6-VDFN package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm. Surface-mount — the small footprint leaves room for decoupling caps near the supply pins on a dense automotive ECU layout. Product status is Active from Microchip Technology.","metaTitle":"DSC1221DI3-148M5000 XO (Standard) 148.5 MHz CMOS MEMS","metaDescription":"AEC-Q100 qualified MEMS oscillator, 148.5 MHz CMOS output, ±20 ppm stability, -40°C to 85°C, 2.5V-3.3V supply.

Suitable for under-hood and cabin applications where the ambient temperature stays within -40°C to 85°C."},{"question":"Does DSC1221DI3-148M5000 have an enable/disable function?","answer":"Yes — the function is listed as Enable/Disable. When disabled, the supply current drops to 23 mA typical from the 27 mA typical active draw, useful for power gating in battery-backed or low-power modes."},{"question":"Can DSC1221DI3-148M5000 replace a standard quartz oscillator?","answer":"Functionally yes — it is a drop-in XO replacement with CMOS output. The MEMS resonator offers better shock and vibration tolerance compared to a quartz crystal, and the ±20 ppm stability is comparable to many quartz-based XOs. Pin compatibility depends on the specific quartz part; verify the 6-VDFN footprint matches your existing layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1221DI3-148M5000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1221DI3-148M5000 when reusing this data.
