A via array under the pad helps spread heat and reduce ground inductance. Microchip lists the DSC1522AI2A-12M80000T as Active — it is in production and suitable for new designs.","metaTitle":"DSC1522AI2A-12M80000T XO (Standard) MEMS Oscillator –","metaDescription":"Active XO (Standard) MEMS oscillator from Microchip Technology. 12.8 MHz, LVCMOS output, ±25 ppm stability, 2.5V–3.3V supply, -40°C to 85°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":"LVCMOS","Series":"DSC152X","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"12.8 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-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":"2.5V ~ 3.3V","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"7.5mA","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/d9dca5041ca10c8cda7b15a6499a28d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What supply voltage does this oscillator require?","answer":"The DSC1522AI2A-12M80000T operates from 2.5V to 3.3V.

The MEMS resonator eliminates quartz startup jitter and frequency-pulling from board parasitics, but the output is still LVCMOS and the supply range is standard. Confirm the enable polarity and output drive strength against your existing quartz part before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1522AI2A-12M80000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1522AI2A-12M80000T when reusing this data.
