For a UART baud-rate clock at 115200 bps, ±50 ppm keeps the bit timing error under 0.5%, well inside the 2% margin most UARTs tolerate. The oscillator starts in under 5 ms typical, which matters for a microcontroller waking from deep sleep. ## Supply current and standby — power budget fit Draws 3 mA typical during operation — low enough to share a 3V rail with a low-power MCU without a dedicated LDO. The 3V supply is fixed — not a wide-range input. The rail must stay within 3V ±10 % to guarantee the frequency stability and output swing. ## Package and temperature — board-fit constraints 4-SMD no-lead package, 3.20 mm x 2.50 mm footprint, 0.90 mm seated height.","metaTitle":"DSC1030CI1-007.3728T MEMS XO, 7.3728 MHz, ±50 ppm, Active","metaDescription":"Microchip DSC1030CI1-007.3728T is an active XO (Standard) with CMOS output, 7.3728 MHz, ±50 ppm stability, 3V supply, and 3 mA typ current.","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":"DSC1030, PureSilicon™","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"7.3728 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":"3V","Base Product Number":"DSC1030","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"0°C~70°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/4b72b94fabfa3cb5855b7b290e3a940f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the frequency stability of DSC1030CI1-007.3728T?","answer":"±50 ppm."},{"question":"What is the output type of DSC1030CI1-007.3728T?","answer":"CMOS output — a rail-to-rail square wave compatible with standard digital logic inputs.
