Product details

Supply voltage flexibility and power-down standby

The 1.8V to 3.3V supply range lets the oscillator run directly from a 1.8V core rail or a 3.3V I/O rail without an intermediate LDO, simplifying power tree design. Active current draw is 8.7 mA max at 133.3333 MHz, a low figure for a MEMS oscillator at this frequency, keeping the thermal footprint small in dense 4-SMD layouts.

Package, footprint, and mounting

Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1001CI1-133.3333 fits standard 3.2 x 2.5 mm oscillator footprints and is compatible with reflow soldering profiles for surface-mount assembly.

Frequently asked questions

What supply voltage range does the DSC1001CI1-133.3333 accept?

The oscillator operates from 1.8V to 3.3V, covering common 1.8V, 2.5V, and 3.3V logic rails without an external regulator.

Can the DSC1001CI1-133.3333 replace a standard quartz oscillator in an automotive design?

Yes. The MEMS resonator is inherently more resistant to vibration and thermal shock than quartz, and the AEC-Q100 qualification makes it a drop-in replacement for quartz oscillators in the same 3.2 x 2.5 mm footprint, provided the supply voltage and output type (CMOS) match the existing circuit.

Does the DSC1001CI1-133.3333 have AEC-Q100 qualification?

Yes, the DSC1001CI1-133.3333 is rated AEC-Q100, qualifying it for automotive applications including under-hood and chassis-mounted electronics where extended temperature range and reliability are required.
