The MEMS resonator makes it more shock- and vibration-tolerant than quartz-based equivalents, but the electrical interface is identical."},{"question":"Can DSC1103AE1-083.3333 operate with a 2.5 V supply?","answer":"Yes. The supply voltage range is 2.25 V to 3.63 V, so 2.5 V is well within the operating window. The LVDS output common-mode voltage and swing will shift proportionally with the supply, but remain within the LVDS receiver input range as long as the receiver is referenced to the same supply."},{"question":"What is the frequency stability of DSC1103AE1-083.3333?","answer":"The frequency stability is ±50 ppm over the -20°C to 70°C operating temperature range. This includes initial tolerance, temperature drift, and aging effects. For applications requiring tighter stability (e.g., ±25 ppm for SyncE), consider the DSC1103 series variants with higher stability grades."},{"question":"Does DSC1103AE1-083.3333 have spread spectrum capability?","answer":"No. The DSC1103 series does not include spread spectrum modulation. The output is a fixed-frequency LVDS clock. For spread spectrum clocking, look at Microchip's DSC400 or DSC6000 families."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1103AE1-083.3333","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1103AE1-083.3333 when reusing this data.
