Both outputs can be configured as HCSL or LVPECL, making it a direct clock source for PCIe, SATA, or 10GbE reference clocks without external level translation. For a 100 MHz carrier, that translates to a maximum absolute frequency error of 5 kHz — well within the ±100 ppm holdover window most Ethernet PHYs require. ## Supply current and power budget fit Typical supply current is 76 mA with both outputs active at 100 MHz. ## Active production and ordering path Microchip lists the DSC2042FI1-F0014 as Active.","metaTitle":"DSC2042FI1-F0014 Microchip Technology MEMS XO, Dual 100 MHz","metaDescription":"Active MEMS XO with two 100 MHz outputs, ±50 ppm stability, HCSL/LVPECL, -40°C to 85°C. 14-VFQFN.

It is pin- and function-compatible with many standard 14-VFQFN dual-output oscillators, but the MEMS die has different phase-noise and aging characteristics than a quartz counterpart. Review the Microchip DSC2042 phase-noise plot against your system's jitter budget before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC2042FI1-F0014","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC2042FI1-F0014 when reusing this data.
