Maximum supply current is 7.2 mA during active oscillation, and the disable current is 15 µA — the 480:1 ratio between run and standby current makes the standby pin a real power-save feature, not a datasheet footnote.","metaTitle":"DSC1001CI2-049.1520T XO 49.152 MHz CMOS MEMS Oscillator","metaDescription":"Microchip DSC1001CI2-049.1520T XO (Standard) MEMS oscillator, 49.152 MHz CMOS output, ±25ppm stability, 1.8V-3.3V supply, AEC-Q100, -40°C~85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1001","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"49.152 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2450","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1001CI2-049.1520T compatible with both 1.8V and 3.3V supplies?","answer":"Yes. The supply voltage range is 1.8V to 3.3V, so the same oscillator works on a 1.8V core rail or a 3.3V I/O rail without a separate voltage translator. The CMOS output swings rail-to-rail, matching the logic family of the downstream IC."},{"question":"What is the standby (power-down) behavior of this oscillator?","answer":"When the standby pin is asserted, the oscillator stops and the supply current drops to 15 µA max. The output goes high-impedance, which lets the downstream clock input float or be pulled low by an external resistor. This is useful for sleep-mode circuits where the clock must be disabled to save power."},{"question":"Can I use the DSC1001CI2-049.1520T in an automotive design?","answer":"Yes. It carries an AEC-Q100 rating, which means it has passed automotive-grade reliability tests including temperature cycling, ESD, and latch-up."},{"question":"What is the frequency stability of this oscillator?","answer":"Frequency stability is ±25ppm over the full operating temperature range. This is tight enough for most CAN, LIN, and Ethernet clocking without external trimming. For applications requiring better than ±25ppm, a different stability grade in the DSC1001 family would be needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI2-049.1520T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI2-049.1520T when reusing this data.
