The 3.3V supply rail and ±50ppm frequency stability suit it for general-purpose clocking in industrial-temperature environments (-40°C to 85°C). ## Standby function and low power draw The part includes a Standby (Power Down) function. When disabled, the supply current drops to 1µA maximum, compared to 3mA typical when running. This makes it suitable for battery-powered or duty-cycled applications where the clock can be gated off between active periods. ## 2.5 mm x 2.0 mm no-lead package Housed in a 4-SMD, No Lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm. The small footprint and low profile fit space-constrained PCB layouts, but the no-lead construction means the solder joints are under the body — X-ray inspection is recommended after reflow.","metaTitle":"DSC1033DI1-033.3330T MEMS XO 33.333 MHz CMOS Obsolete –","metaDescription":"DSC1033DI1-033.3330T is an obsolete MEMS oscillator, 33.333 MHz, CMOS output, 3.3V, ±50ppm, -40°C to 85°C.","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":"33.333 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"3mA (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":"Is DSC1033DI1-033.3330T obsolete?","answer":"Yes, Microchip lists the DSC1033DI1-033.3330T as Obsolete.
