The 1.7V to 3.6V supply range lets it run directly from a 1.8V or 3.3V rail without an intermediate LDO, saving one regulator and its associated decoupling capacitors on the BOM. Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1001CI5-099.9990 occupies roughly the same PCB area as a 3225 quartz crystal but eliminates the need for external load capacitors. The MEMS resonator construction typically carries shorter lead times than quartz equivalents because the die is fabricated on a standard CMOS line — no quartz crystal blank sourcing, no frequency trimming per batch.","metaTitle":"DSC1001CI5-099.9990 MEMS XO – 99.999 MHz, AEC-Q100, CMOS","metaDescription":"Microchip DSC1001CI5-099.9990: MEMS XO, 99.999 MHz, ±10 ppm, CMOS output, AEC-Q100, 1.7-3.6V, -40 to 85°C, standby function.

This means it has passed the automotive-grade stress tests: high-temperature operating life, temperature cycling, ESD, and latch-up. It is suitable for under-hood and cabin electronics where the ambient temperature reaches 85°C and the supply rail may see transients."},{"question":"What does the standby (power down) function do on this oscillator?","answer":"The standby function disables the output and places the internal circuitry into a low-power state. In standby, the maximum supply current drops to 15 µA, compared to 10.5 mA when active. This is useful for battery-powered or intermittently operated systems — the oscillator stops consuming power when the downstream processor is asleep, and the output returns to valid CMOS levels within the startup time specified in the datasheet."},{"question":"What is the frequency stability of the DSC1001CI5-099.9990?","answer":"This tighter-than-typical stability (±25 ppm is common for standard XOs) means the oscillator meets the timing jitter budget for 100BASE-T1 Ethernet, USB 2.0, and precision sensor sampling without additional clock conditioning."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI5-099.9990","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI5-099.9990 when reusing this data.
