The 2.25V to 3.6V supply range covers standard 2.5V and 3.3V rails without a separate LDO — the oscillator runs directly off the same rail as the FPGA or MCU bank, simplifying the power tree. Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint matches the common 3.2 x 2.5 mm oscillator land pattern — a drop-in replacement for quartz oscillators in that form factor, though the MEMS die eliminates the need for a decoupling capacitor on the output.","metaTitle":"DSC1121CE5-048.0000 MEMS XO 48 MHz CMOS ±10 ppm – Microchip","metaDescription":"Active Microchip DSC1121CE5-048.0000 XO (Standard) 48 MHz CMOS output, ±10 ppm stability, 2.25V–3.6V supply, 6-VDFN package.

Submit an RFQ with your target quantity; we confirm current pricing and lead time against your BOM line. No stock-holding claim — availability is confirmed per inquiry."},{"question":"Can the DSC1121CE5-048.0000 directly replace a standard 48 MHz quartz crystal oscillator?","answer":"Yes, if the existing quartz oscillator uses a 3.2 mm x 2.50 mm footprint and runs on a 2.25V–3.6V supply with CMOS output. The MEMS-based DSC1121CE5-048.0000 offers tighter ±10 ppm stability versus typical ±25 ppm or ±50 ppm quartz, and it does not require an external load capacitor on the output — the MEMS resonator is self-contained. Confirm the Enable/Disable pin polarity matches your circuit."},{"question":"Is the DSC1121CE5-048.0000 compatible with a 3.3V supply?","answer":"Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec. The 48 MHz CMOS output levels track the supply rail — at 3.3V the output high is approximately 3.3V, compatible with 3.3V logic families."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CE5-048.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CE5-048.0000 when reusing this data.
