Quoted to order against the BOM; availability and pricing confirmed at RFQ. ## 40 MHz MEMS oscillator for industrial timing A 40 MHz XO (Standard) oscillator built on a MEMS resonator rather than a quartz crystal — the MEMS base gives better shock and vibration tolerance than a traditional crystal oscillator, relevant for equipment that sees mechanical stress during transport or operation. The 4 mA typical supply current keeps the power budget low for a 40 MHz clock source. ## Standby function and package footprint Includes a Standby (Power Down) function that drops supply current to 1 µA max — useful for battery-powered designs that need to disable the clock tree during sleep modes. Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts without requiring a dedicated oscillator footprint.","metaTitle":"DSC1033CI1-040.0000T MEMS Oscillator 40 MHz CMOS - Microchip","metaDescription":"DSC1033CI1-040.0000T Microchip MEMS XO, 40 MHz, CMOS output, ±50 ppm stability, -40°C to 85°C, 3.3V, 4-SMD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1033, PureSilicon™","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"40 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"4mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for DSC1033CI1-040.0000T?","answer":"Microchip does not list an official successor or pin-compatible cross-reference for this order code.
