The Enable/Disable function lets the output be tri-stated (22 mA max supply in disable) for power-down or test modes without cycling the main supply rail. ## Supply voltage and package fit for BOM planning Operating from 2.25V to 3.6V, this oscillator covers 2.5V and 3.3V logic rails directly — no extra LDO needed in the clock tree. Housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, it fits tight PCB layouts common in automotive ECUs and industrial controllers. Maximum supply current is 35 mA during active operation, a figure to budget in the power rail design for multi-oscillator arrays.","metaTitle":"DSC1121CI2-074.2500 MEMS Oscillator 74.25 MHz AEC-Q100","metaDescription":"Microchip DSC1121CI2-074.2500 XO (Standard) MEMS oscillator, 74.25 MHz CMOS output, ±25ppm stability, -40°C to 85°C, AEC-Q100.","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":"DSC1121","Package":"Tube","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"74.25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-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":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the frequency of the DSC1121CI2-074.2500?","answer":"The output frequency is 74.25 MHz, a common clock rate for video and networking applications."},{"question":"Is the DSC1121CI2-074.2500 AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 ratings, making it suitable for automotive-grade designs."},{"question":"Does the DSC1121CI2-074.2500 have an enable/disable function?","answer":"Yes, the Enable/Disable function allows the output to be tri-stated, reducing supply current to 22 mA max when disabled."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CI2-074.2500","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CI2-074.2500 when reusing this data.
