For a 133.3333 MHz clock, ±50 ppm translates to ±6.67 kHz of total frequency error — well within the capture range of most Ethernet PHYs, PCIe reference clocks, and FPGA PLLs that specify ±100 ppm or wider. ## Supply rail and output compatibility Runs from a single 3.3V supply with a maximum current draw of 10 mA during active operation. CMOS output swings rail-to-rail, so it drives standard 3.3V CMOS logic inputs directly. No level translation needed when feeding an FPGA bank, a microcontroller clock input, or a clock buffer that accepts 3.3V CMOS levels. Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm × 5.00 mm (0.276\" × 0.197\") with a seated height of 0.90 mm (0.035\"). The 4-pin footprint is common across the DSC1033 family, so a single PCB layout can accommodate multiple frequency variants by populating the correct order code.","metaTitle":"DSC1033AE1-133.3333 MEMS Oscillator 133.3333 MHz CMOS 3.3V","metaDescription":"Microchip DSC1033AE1-133.3333 XO (Standard) MEMS oscillator, 133.3333 MHz CMOS output, 3.3V supply, ±50 ppm stability, -20°C to 70°C, 4-SMD package.","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":"DSC1033, PureSilicon™","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"133.3333 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-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":"3.3V","Base Product Number":"DSC1033","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"10mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4748","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact frequency of DSC1033AE1-133.3333?","answer":"The oscillator outputs a fixed 133.3333 MHz CMOS clock signal.

The MEMS resonator offers better shock and vibration immunity than quartz, and no external load capacitors are required. Confirm the pinout matches your existing footprint; the DSC1033 uses a standard 4-pin assignment (enable, GND, output, Vdd)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033AE1-133.3333","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033AE1-133.3333 when reusing this data.
