An integrated Enable/Disable function allows the output to be tri-stated, reducing max supply current from 35 mA to 22 mA when the clock is not needed — useful for power-sensitive or test modes. ## Package and mounting for board integration Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1121AI2-048.0000 is a surface-mount oscillator that fits standard clock footprints. The MEMS base resonator provides inherent shock and vibration tolerance compared to quartz crystals, reducing startup reliability issues in harsh environments.","metaTitle":"DSC1121AI2-048.0000 MEMS Oscillator 48 MHz AEC-Q100","metaDescription":"DSC1121AI2-048.0000 from Microchip Technology: MEMS XO, 48 MHz, CMOS output, AEC-Q100 qualified, -40°C to 85°C, 2.25V-3.6V supply.","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":"48 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-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":"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 exact frequency of the DSC1121AI2-048.0000?","answer":"The exact output frequency is 48 MHz, with a CMOS output and ±25 ppm frequency stability."},{"question":"Is the DSC1121AI2-048.0000 AEC-Q100 qualified?","answer":"Yes, it carries an AEC-Q100 rating, making it suitable for automotive applications that require the associated reliability and qualification testing."},{"question":"Does the DSC1121AI2-048.0000 have an enable/disable feature?","answer":"Yes, the oscillator includes an Enable/Disable function.
