It operates across a wide supply range of 2.25V to 3.63V, making it compatible with common 2.5V and 3.3V logic rails without an external regulator.
Housed in a 6-VDFN package measuring 2.50mm x 2.00mm with a seated height of 0.90mm, the DSC1101DI1-033.3330T occupies minimal PCB area. The CMOS output swings rail-to-rail, simplifying interface to downstream logic without level translation.
The DSC1101DI1-033.3330T is available through independent distribution. Submit a request for a firm quote.
Yes. The base resonator is MEMS, not quartz. MEMS oscillators offer better shock and vibration tolerance, faster startup, and smaller footprint compared to quartz-based XOs, though frequency stability (±50 ppm) is comparable.
Functionally yes, if the application requires a 33.333 MHz CMOS clock with ±50 ppm stability and a 2.25V to 3.63V supply. The 6-VDFN package is smaller than most quartz SMD packages, so the PCB footprint must be verified. No pin-compatible quartz alternative is listed by Microchip for this series.
Yes. The Standby (Power Down) function disables the output and reduces supply current to 95 µA max, enabling low-power sleep modes in battery-operated or intermittently powered systems.
Yes. The supply voltage range is 2.25V to 3.63V, so a 3.3V rail is within specification. The CMOS output swings rail-to-rail, so no level translation is needed when driving 3.3V logic.
