The key difference is the MEMS die inside: it eliminates quartz's frequency drift from mechanical shock and offers a faster start-up time, though the datasheet's ±50 ppm stability is comparable to a good quartz part. For a BOM line currently using a generic 19.2 MHz CMOS oscillator, this part upgrades the vibration and temperature performance without a board spin.","metaTitle":"DSC1001CI1-019.2000 MEMS Oscillator – AEC-Q100, 19.2 MHz","metaDescription":"Microchip DSC1001CI1-019.2000 XO (Standard) MEMS oscillator, 19.2 MHz CMOS output, ±50 ppm stability, -40°C to 85°C, AEC-Q100 qualified.","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":"Tube","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"19.2 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":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"6.3mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9150","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1001CI1-019.2000 a direct replacement for a standard 19.2 MHz quartz oscillator?","answer":"Yes, it is a drop-in replacement in terms of footprint (4-SMD no-lead), supply voltage (1.8V–3.3V), and CMOS output.
