The ±50 ppm stability matches many commercial-grade quartz parts. The standby (power-down) function is an added feature that a basic quartz oscillator may not offer — verify that the enable pin logic aligns with your circuit's power-down scheme."},{"question":"What is the standby current of DSC1033AE1-040.0000T?","answer":"The maximum supply current in disable (standby) mode is 1 µA. This makes the part suitable for battery-powered equipment where the oscillator must remain connected to the supply rail but draw negligible current when the system is asleep."},{"question":"Is DSC1033AE1-040.0000T compatible with a 2.5 V supply?","answer":"No — the specified supply voltage is 3.3 V only. For a 2.5 V rail, look at the DSC1033 family variants with a 2.5 V option (check the base product number DSC1033 suffix)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033AE1-040.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033AE1-040.0000T when reusing this data.
