Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without a separate regulator; the 35 mA max supply current is typical for a 40 MHz CMOS output stage. Microchip lists the DSC1101DM5-040.0000T as Obsolete. ## 6-VDFN package and board layout Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint for space-constrained designs. Surface-mount assembly; the small pad pitch demands careful stencil design to avoid solder bridging.","metaTitle":"DSC1101DM5-040.0000T MEMS XO 40 MHz CMOS Obsolete —","metaDescription":"Microchip DSC1101DM5-040.0000T MEMS XO, 40 MHz CMOS output, ±10 ppm stability, -55°C to 125°C.

For a new design, consider a current-production MEMS oscillator from the DSC11xx family with the same 2.50 mm x 2.00 mm 6-VDFN footprint and 40 MHz CMOS output — confirm the supply voltage range and temperature grade against your BOM requirements."},{"question":"Can I use the DSC1101DM5-040.0000T in a 3.3V system?","answer":"Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within specification. The CMOS output swings rail-to-rail, so the logic-high level matches a 3.3V input without level translation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1101DM5-040.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1101DM5-040.0000T when reusing this data.
