It operates from a 1.8V to 3.3V supply rail, drawing 6.3 mA max in active mode and just 15 µA in standby (power-down) — the standby pin lets the system gate the clock for power savings without an external load switch. The AEC-Q100 qualification confirms it meets the stress and reliability tests required for under-hood and chassis-domain deployments. Microchip lists the DSC1001CL1-022.5790 as Active. The 4-SMD, no-lead package (3.20 mm x 2.50 mm footprint, 0.90 mm seated height) is a common MEMS oscillator footprint — compatible with standard reflow profiles and pick-and-place equipment. ## Wide supply range and standby power-down The 1.8V–3.3V supply range means the oscillator can run from a 1.8V core rail, a 2.5V I/O rail, or a 3.3V system rail without a dedicated regulator — useful in multi-voltage designs where the clock domain spans several power islands.","metaTitle":"DSC1001CL1-022.5790 – Microchip MEMS XO, 22.579 MHz, CMOS","metaDescription":"DSC1001CL1-022.5790 from Microchip Technology: 22.579 MHz MEMS XO, CMOS output, 1.8V-3.3V supply, -40°C to 105°C, AEC-Q100 qualified, standby function.","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":"22.579 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~105°C","Current - Supply (Max)":"6.3mA","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":"What is the frequency of DSC1001CL1-022.5790?","answer":"The DSC1001CL1-022.5790 outputs a fixed 22.579 MHz CMOS clock.
