The MEMS resonator replaces a quartz crystal, giving better shock and vibration immunity and a faster start-up time compared to a traditional crystal oscillator — relevant for automotive camera modules or ADAS sensor clocks where the oscillator must lock quickly after a power-on reset. ## Supply range and standby current Operating from a 1.8V to 3.3V supply, this oscillator spans the common digital core and I/O rails — a single BOM line covers 1.8V, 2.5V, or 3.3V domains without a separate voltage translator. Standby (Power Down) function drops the supply current to 15 µA max when the enable pin is pulled low — useful for battery-backed modules that need to preserve the clock tree during sleep and wake on a timer or external event. Active supply current is 8.7 mA max at 70.455 MHz — the MEMS core draws less than a comparable quartz oscillator at this frequency, which matters for thermally constrained layouts in a sealed automotive ECU. Housed in a no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the compact footprint fits into space-constrained designs. Surface-mount mounting with standard reflow profiles; the no-lead package has a flat bottom with solder pads on the underside, so the PCB land pattern should match the recommended footprint in the datasheet to avoid tombstoning during reflow. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001CI5-070.4550 MEMS Oscillator – Microchip, 70.455 MHz","metaDescription":"DSC1001CI5-070.4550 XO (Standard) MEMS oscillator from Microchip. 70.455 MHz CMOS output, ±10 ppm stability, 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":"70.455 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":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"8.7mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC1001CI5-070.4550 or check availability?","answer":"Submit an RFQ with your target quantity and target price; we confirm current availability and lead time at quote time.
