The DSC1033 base product number covers a family of frequencies and stability grades; the CI2 suffix identifies this specific 37.125 MHz, ±25 ppm, -40 to 85 °C variant.","metaTitle":"DSC1033CI2-037.1250 MEMS XO – 37.125 MHz, CMOS, Standby","metaDescription":"Microchip DSC1033CI2-037.1250 XO (Standard) with MEMS resonator, 37.125 MHz CMOS output, ±25 ppm stability, 3.3V supply, standby power-down, 1 µA disable","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":"37.125 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-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":"3.3V","Base Product Number":"DSC1033","Frequency Stability":"±25ppm","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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1033CI2-037.1250/alternatives.json"},"ai":{"faq":[{"question":"Can DSC1033CI2-037.1250 replace a quartz oscillator of the same frequency?","answer":"Yes, in most cases. The DSC1033CI2-037.1250 is a MEMS-based XO with CMOS output and a standard 4-SMD footprint — it is pin-compatible with many 3.3 V quartz oscillators in the same 3.2 mm x 2.5 mm package. Confirm the enable/disable logic polarity matches your design; the standby function on this part is active-low power-down."},{"question":"What is the standby power-down function on DSC1033CI2-037.1250?","answer":"The standby (power-down) function disables the output and reduces current consumption to 1 µA max. This allows the system to gate the clock off between active periods, saving power in battery-operated or duty-cycled designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033CI2-037.1250","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033CI2-037.1250 when reusing this data.
