Housed in a 6-VDFN with exposed pad (7.00 mm x 5.00 mm, 0.90 mm seated height), the part requires a thermal via pattern under the pad for heat dissipation — a standard two-layer board with a ground-plane stitch works, but the pad must be soldered to the PCB, not left floating. The 0.276\" x 0.197\" footprint matches industry-standard 7x5 mm oscillator land patterns, so it drops into existing layouts without a board spin if the supply voltage and output type align. Listed as Active by Microchip — no end-of-life notice, no NRND flag.","metaTitle":"DSC1121AI2-081.0000T MEMS Oscillator 81 MHz CMOS - Microchip","metaDescription":"Active Microchip DSC1121AI2-081.0000T XO (Standard) MEMS oscillator, 81 MHz CMOS output, 2.25-3.6V supply, ±25 ppm stability, -40°C to 85°C, 6-VDFN 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":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"81 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN 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":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the frequency of DSC1121AI2-081.0000T?","answer":"The oscillator outputs a fixed 81 MHz CMOS clock signal."},{"question":"What supply voltage does DSC1121AI2-081.0000T need?","answer":"It operates from 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an external regulator."},{"question":"What package does DSC1121AI2-081.0000T come in?","answer":"It is supplied in a 6-VDFN exposed-pad package measuring 7.00 mm x 5.00 mm, 0.90 mm seated height."},{"question":"How do I get pricing and availability for DSC1121AI2-081.0000T?","answer":"Submit an RFQ through the storefront.
