Supply voltage tolerance spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails directly — no separate regulator needed for the oscillator supply. The 6-SMD no-lead package (3.20 mm x 2.50 mm footprint) suits dense PCB layouts where a quartz crystal plus oscillator IC would consume more board area. ## MEMS resonator advantage over quartz MEMS oscillators typically offer better shock and vibration immunity, which matters in outdoor telecom or industrial equipment where board-level vibration can pull a quartz crystal's frequency outside the ±10 ppm window.","metaTitle":"DSC1122CI5-156.2500 – 156.25 MHz LVPECL MEMS XO, Active","metaDescription":"DSC1122CI5-156.2500 XO (Standard) from Microchip Technology: 156.25 MHz, LVPECL output, ±10 ppm stability, -40°C to +85°C, 2.25-3.6 V supply, active production.","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":"DSC1122","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"156.25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1122","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"58mA","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/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC1122CI5-156.2500 or check stock?","answer":"The DSC1122CI5-156.2500 is an active-production part.
