The 6-VDFN package (7.00mm x 5.00mm, 0.90mm height) is a standard footprint for 5x7 mm oscillators; the low profile suits tight card cages. Microchip lists the DSC1212NI1-C0027T as Active. ## What the LVPECL output means for your board LVPECL is a differential logic standard with a typical swing of 800 mV peak-to-peak centered around a 2V common-mode voltage. It requires 50-ohm termination to VCC-2V at the receiver — the layout must include the termination resistors and a clean AC-coupled path. The 50mA typical supply current includes the output driver current; budget this into the power rail sizing.","metaTitle":"DSC1212NI1-C0027T MEMS XO LVPECL Oscillator","metaDescription":"DSC1212NI1-C0027T: Active XO (Standard), LVPECL output, ±50ppm stability, -40°C to 85°C, 2.5V-3.3V supply, 6-VDFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"LVPECL","Series":"DSC12X2","Package":"Tape & Reel (TR)","Function":"-","Base Resonator":"MEMS","Package / Case":"6-VDFN","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":"±50ppm","Frequency - Output 1":"-","Frequency - Output 2":"-","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C ~ 85°C","Current - Supply (Max)":"50mA (Typ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9c9562275ed01929df10cd035ac9614e.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1212NI1-C0027T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1212NI1-C0027T when reusing this data.
