For a 10 MHz clock, ±10 ppm is ±100 Hz of absolute error, which keeps the timing margin comfortable for USB full-speed (12 MHz) or 10/100 Ethernet reference clocks. ## Supply range and current draw The supply voltage range is 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails. Maximum supply current is 22 mA — typical for a 10 MHz CMOS oscillator; the actual draw depends on the load capacitance on the output. ## Package, mounting, and temperature grade Housed in a 6-SMD, no-lead exposed-pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. This limits deployment to indoor, office, or consumer environments. Not rated for industrial floor or outdoor telecom enclosures without active temperature management.","metaTitle":"DSC1121AE5-010.0000T MEMS Oscillator 10 MHz CMOS XO –","metaDescription":"Microchip DSC1121AE5-010.0000T XO (Standard) 10 MHz CMOS output MEMS oscillator. ±10 ppm stability, 2.25-3.6 V supply, -20°C to 70°C.","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":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"10 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-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":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"22mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can DSC1121AE5-010.0000T replace a standard 10 MHz quartz oscillator?","answer":"Yes, it is a direct drop-in replacement for a 10 MHz quartz XO with CMOS output and enable/disable function. The MEMS base resonator means better shock tolerance (tested to 50 g) and faster lead times than quartz.
