That means the clock edge stays within 875 Hz of 87.5 MHz regardless of whether the rail dips during a cold crank or the ambient hits 85°C under the dashboard. The 4-SMD no-lead package (3.20mm x 2.50mm) fits the same footprint as quartz oscillators, so a board designed for a quartz can is a direct drop-in. ## Standby power gating and supply flexibility For an ECU that spends most of its life in sleep, this microamp-level draw keeps the quiescent load off the battery. Active supply current is 9.6 mA max at 87.5 MHz, which is typical for a MEMS oscillator at this frequency and well within the budget of a 3.3V or 2.5V rail. The 1.7V-3.6V input range means the same part works on a 1.8V core supply or a 3.3V I/O bank without a separate level translator. ## Active production — quoted per BOM quantity The base product number DSC1003 covers the family; the full suffix CI5-087.5000 locks the frequency, stability grade, and temperature range.","metaTitle":"DSC1003CI5-087.5000 MEMS Oscillator 87.5 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1003CI5-087.5000 XO (Standard) MEMS oscillator, 87.5 MHz CMOS output, ±10 ppm stability, -40°C to 85°C, AEC-Q100, 1.7V-3.6V supply.","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":"DSC1003","Package":"Tube","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"87.5 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":"1.7V ~ 3.6V","Base Product Number":"DSC1003","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"9.6mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact frequency of DSC1003CI5-087.5000?","answer":"The oscillator outputs a fixed 87.5 MHz CMOS clock.
