The MEMS resonator eliminates quartz start-up time and vibration sensitivity, making it a fit for telecom line cards, FPGA reference clocks, and industrial Ethernet PHYs that need a clean 50 MHz differential clock. ## Wide supply range and industrial temperature grade Rated for -40 to +85°C with ±25 ppm frequency stability, this oscillator suits outdoor base stations, motor drives, and engine-bay controllers where ambient temperature swings are routine. ## Compact 6-SMD no-lead package Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint suits dense PCB layouts — the Enable/Disable function on pin 1 allows the oscillator to be tri-stated, reducing supply current from 58 mA (max) to 22 mA (max) when the clock is not needed, which helps thermal management in a tight layout.","metaTitle":"DSC1122DI2-050.0000 – Microchip MEMS XO, LVPECL, 50 MHz","metaDescription":"Active Microchip DSC1122 series MEMS oscillator, 50 MHz LVPECL output, 2.25-3.6 V supply, -40 to +85°C, ±25 ppm stability. 6-SMD no-lead 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":"DSC1122","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"50 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1122","Frequency Stability":"±25ppm","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":"Is DSC1122DI2-050.0000 compatible with 2.5V logic families?","answer":"Yes. At a 2.5 V supply, the differential output levels are directly compatible with 2.5 V LVPECL receivers without external level translation."},{"question":"How does this MEMS oscillator differ from a standard 50 MHz quartz crystal oscillator?","answer":"The DSC1122 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically have faster start-up, better vibration and shock resistance, and no quartz aging drift. The output is LVPECL (differential) rather than a single-ended CMOS or sine wave, which gives better noise immunity for high-speed clock distribution."},{"question":"What is the frequency stability of DSC1122DI2-050.0000?","answer":"The frequency stability is ±25 ppm over the full -40 to +85°C operating temperature range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122DI2-050.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122DI2-050.0000 when reusing this data.
