Housed in a 4-SMD, No Lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm — the 0.126\" × 0.098\" footprint matches the industry-standard 3.2×2.5 mm oscillator land pattern, so no pad redesign is needed if replacing a quartz XO of the same size.","metaTitle":"DSC1001CI5-029.4912T Microchip MEMS XO 29.4912 MHz CMOS","metaDescription":"DSC1001CI5-029.4912T: Microchip MEMS XO, 29.4912 MHz CMOS output, ±10 ppm stability, 1.8-3.3 V supply, AEC-Q100.

RoHS compliance is standard for Microchip's DSC1001 series; no exemption flags are listed in the product documentation."},{"question":"How does the standby pin function?","answer":"The standby (power-down) pin disables the output and reduces supply current to 15 µA max. When the pin is asserted low (or open, depending on the configuration), the oscillator stops and the output goes high-impedance — useful for gating the clock in sleep modes without a separate enable switch."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI5-029.4912T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI5-029.4912T when reusing this data.
