This eliminates a second oscillator from the BOM when a design needs both a high-speed SerDes reference and a lower-speed system clock. Outputs are configurable as HCSL or LVPECL, the standard differential signalling formats for PCIe, 10GbE, and FPGA reference clocks. A single device can feed two clock domains without external fanout buffers. ## Stability and supply range for industrial timing This holds the clock edge jitter tight enough for 125 MHz LVPECL into a 100BASE-TX PHY or a Xilinx 7-series GTX transceiver reference. Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an intermediate LDO. ## Active lifecycle and package fit Product status is Active. Housed in a 14-VFQFN with exposed pad, 3.20 x 2.50 mm body, 0.90 mm height. Supplied in tape and reel, compatible with automated pick-and-place assembly.","metaTitle":"DSC2042FI2-M0004T MEMS XO – 125 MHz & 25 MHz, HCSL/LVPECL","metaDescription":"DSC2042FI2-M0004T: Active MEMS XO from Microchip, dual output 125 MHz & 25 MHz, HCSL/LVPECL, ±25 ppm stability, 2.25-3.6 V, -40 to 85 °C, 14-VFQFN.","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":"HCSL, LVPECL","Series":"DSC2042","Package":"Tape & Reel (TR)","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"14-VFQFN Exposed Pad","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":"DSC2042","Frequency Stability":"±25ppm","Frequency - Output 1":"125MHz","Frequency - Output 2":"25MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"76mA (Typ)","Current - Supply (Disable) (Max)":"23 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/44c3094e23a3acf8019dbf6f002d7405.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC2042FI2-M0004T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC2042FI2-M0004T when reusing this data.
