Product details

The DSC1004CI2-054.0000T: Its AEC-Q100 qualification makes it suitable for under-hood and cabin automotive electronics, as well as factory-floor and outdoor telecom equipment where thermal cycling and vibration are routine.

Standby power-down cuts quiescent current to 15 µA

Wide supply range simplifies voltage-domain bridging

The oscillator operates from a single 1.8V to 3.3V supply, covering the common logic rails used in automotive MCUs, FPGAs, and transceivers. No external level translator is needed when moving between a 1.8V core and a 3.3V I/O bank — the same part serves both domains.

Frequently asked questions

Is DSC1004CI2-054.0000T AEC-Q100 qualified?

Yes, the DSC1004CI2-054.0000T carries AEC-Q100 ratings, qualifying it for automotive applications including under-hood and cabin environments.

What is the standby function on DSC1004CI2-054.0000T and how does it work?

The standby (power-down) function disables the oscillator output and internal circuitry, reducing supply current from 8 mA max to 15 µA max. A logic-low on the standby pin (per the DSC1004 datasheet) places the part in this low-power state; a logic-high resumes normal oscillation with a fast start-up time. This is useful for sleep-mode power savings in battery-powered or intermittently operated systems.

Does DSC1004CI2-054.0000T have a datasheet?

Yes, a full datasheet is available from Microchip Technology for the DSC1004 series. It covers the standby pin timing, start-up time, output drive strength, and jitter specifications not listed in the brief summary here.
