LVDS is the differential signalling standard for high-speed serial links — think PCIe reference clocks, 10GbE SerDes, FPGA transceiver banks, or video interface PLLs. The 212.5 MHz frequency is a common multiple for 10.3125 Gbps SerDes (×48) and aligns with many FPGA transceiver reference clock multipliers. That's tight enough for most Ethernet and video standards without a TCXO or oven. ## Active lifecycle — no end-of-life clock ticking No last-time-buy window to track. The DSC1123 series is a mature MEMS oscillator family with multiple frequency and stability variants sharing the same 6-pad footprint — if you need a different frequency later, the BOM change is a single line swap.","metaTitle":"DSC1123CI2-212.5000 MEMS XO, LVDS, 212.5 MHz, Active","metaDescription":"Microchip DSC1123CI2-212.5000: MEMS-based XO, LVDS output, 212.5 MHz, ±25 ppm stability, -40 to 85°C, 2.25-3.63V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVDS","Series":"DSC1123","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"212.5 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 ~ 3.63V","Base Product Number":"DSC1123","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"32mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32c33983bfd645bac8d0b2ac5207c872.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC1123CI2-212.5000 or get a quote?","answer":"This part is active and available through independent distribution. Submit an RFQ with your target quantity and lead-time window — we source against your BOM line and confirm availability at quote time. No stock-holding claim; confirmed per RFQ."},{"question":"Does the DSC1123CI2-212.5000 require an external crystal or load capacitors?","answer":"No. The MEMS resonator and oscillator circuit are integrated inside the 6-SMD package. You supply only power (2.25-3.63 V) and an enable signal. No external crystal, no load caps, no feedback resistor — it's a drop-in clock source."},{"question":"What is the difference between this MEMS oscillator and a standard quartz oscillator?","answer":"The MEMS resonator is a silicon micro-electromechanical structure sealed at the die level, versus a quartz crystal blank in a metal can. MEMS oscillators typically have better shock and vibration tolerance, faster start-up, and a smaller footprint (3.2 x 2.5 mm here). The electrical interface — LVDS output, supply range, enable/disable — is the same as a quartz XO, so it's a pin-compatible swap on the same 6-pad layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123CI2-212.5000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123CI2-212.5000 when reusing this data.
