That puts it in the under-hood or cabin-ambient band where a quartz oscillator would drift past the ±50 ppm window under thermal shock. The MEMS resonator handles 50,000 g shock and 70 g vibration typical — no startup settling time, no activity dips. ## 22.579 MHz output – audio and serial clock 22.579 MHz is the standard audio master clock for 44.1 kHz sample rates (×512). It also drives USB full-speed (12 MHz × 1.88) and some CAN-FD controllers. The CMOS output swings rail-to-rail across the full 1.8V–3.3V supply range, so the same oscillator can feed a 1.8V MCU and a 3.3V PHY without a level translator. ## MEMS construction – why it matters for the BOM That means no frequency shift from board flex or reflow profile, no microphonic sensitivity, and no start-up delay. It also eliminates the external load capacitors a quartz crystal needs — one fewer component per clock tree. ## Package and assembly fit 3.20 mm × 2.50 mm × 0.90 mm 4-SMD no-lead package — same footprint as a standard 3225 quartz oscillator. The MEMS die inside is epoxy-bonded, so no cavity or hermetic seal to crack. Active product status — no last-time-buy window, no successor. The DSC1001 series is Microchip's mainstream automotive MEMS oscillator family, so second-source risk is low.","metaTitle":"DSC1001CL1-022.5790T MEMS XO – 22.579 MHz, AEC-Q100","metaDescription":"Microchip DSC1001CL1-022.5790T: 22.579 MHz MEMS oscillator, ±50 ppm stability, 1.8V–3.3V supply, -40°C to +105°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":"Tape & Reel (TR)","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 exact frequency of DSC1001CL1-022.5790T?","answer":"22.579 MHz."},{"question":"Is DSC1001CL1-022.5790T AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CL1-022.5790T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CL1-022.5790T when reusing this data.
