The output is a clean HCSL or LVPECL clock, so the downstream PLL or FPGA sees the same edge rates as a quartz-based XO. The ±50 ppm stability covers the same temperature range as most industrial quartz oscillators, and the MEMS construction is inherently more shock- and vibration-tolerant."},{"question":"What is the difference between HCSL and LVPECL outputs?","answer":"HCSL (High-Speed Current Steering Logic) is a differential standard with a 0.7V swing centred around 0.4V, commonly used for PCIe reference clocks. LVPECL (Low-Voltage Positive Emitter-Coupled Logic) swings 0.8V around 2.0V and is typical for high-frequency clock distribution in networking gear. The DSC2042FI1-F0014T can be configured for either, so the same oscillator part number serves both interface types on the board."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC2042FI1-F0014T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC2042FI1-F0014T when reusing this data.
