It delivers a fixed-frequency clock source rated for automotive environments per AEC-Q100. Supply voltage spans 1.8 V to 3.3 V, making it compatible with both 1.8 V and 3.3 V logic domains without an external level translator. ## 7.2 mA active, 15 µA standby — power budget fit Maximum supply current during oscillation is 7.2 mA, while the standby (power-down) mode draws only 15 µA — the standby current is two orders of magnitude lower than the active draw, enabling battery-powered or sleep-mode designs to conserve energy. The standby function disables the output and stops the oscillator, reducing power to the 15 µA level. ## Active lifecycle — no LTB or obsolescence watch ## 4-SMD, no-lead exposed pad — layout note Housed in a 7.00 mm × 5.00 mm 4-SMD package with an exposed pad (no lead). Height seated is 0.90 mm max, fitting within standard 1.0 mm clearance profiles on dense PCBs. The surface-mount package is compatible with reflow soldering; MSL level should be confirmed from the Microchip packaging label.","metaTitle":"DSC1001AE1-066.6660 XO 66.666 MHz CMOS AEC-Q100 MEMS","metaDescription":"Active Microchip Technology DSC1001AE1-066.6660 XO (Standard) MEMS oscillator, 66.666 MHz CMOS output, AEC-Q100 rated, 7.2 mA max supply, 15 µA standby.","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":"66.666 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9450","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1001AE1-066.6660 AEC-Q100 qualified?","answer":"Yes, it carries an AEC-Q100 rating.
