The LVPECL output requires proper termination (typically 50 Ω to VCC - 2V) to maintain signal integrity at 121.109 MHz. Max supply current is 50 mA typ; disabled current drops to 23 mA typ. Housed in a 6-VDFN package measuring 2.50mm x 2.00mm with a seated height of 0.90mm. Surface-mount mounting is standard for automated assembly. The package is supplied in Tube; tape-and-reel availability should be confirmed at RFQ for volume pick-and-place.","metaTitle":"DSC1222DI2-121M1090 MEMS XO – 121.109 MHz LVPECL, Active","metaDescription":"Microchip DSC1222DI2-121M1090: MEMS-based XO, 121.109 MHz, LVPECL output, ±25 ppm, -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":"LVPECL","Series":"DSC1222","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"121.109 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","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)":"50mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"23mA (Typ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9c9562275ed01929df10cd035ac9614e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the frequency stability of DSC1222DI2-121M1090?","answer":"This is tight enough for most Ethernet and SerDes reference clocks without external temperature compensation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1222DI2-121M1090","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1222DI2-121M1090 when reusing this data.
