Product details

MEMS oscillator for wide-temperature timing

Supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without an external LDO — one BOM line serves multiple power domains. Frequency stability is ±50ppm over the full temperature and voltage range, tight enough for most MCU clock inputs and serial-communication timing references.

Standby power-down for battery-sensitive designs

A Standby (Power Down) function drops supply current to 95µA max when the enable pin is de-asserted — useful for battery-powered sensors or IoT nodes that sleep between transmissions and wake on an external event. Active current consumption is 35mA max at 33.3333 MHz, typical for a high-frequency CMOS-output oscillator driving a standard load.

Package and board-fit note

Housed in a 6-VDFN package measuring 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint that fits dense PCB layouts without sacrificing thermal or mechanical reliability.

Product status is Active per the manufacturer — no NRND or EOL notice; suitable for both new designs and ongoing production builds.

Frequently asked questions

Is DSC1101DM1-033.3333 compatible with a 3.3V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec — no external regulator needed.

How does DSC1101DM1-033.3333 compare to a quartz oscillator?

This is a MEMS-based oscillator. Compared to a quartz crystal oscillator, MEMS offers better shock and vibration tolerance, faster start-up, and a wider operating temperature range (-55°C to +125°C) without the frequency-pull effects of quartz over temperature. The trade-off is typically slightly higher phase noise than a high-end quartz OCXO, but for most digital clocking applications the ±50ppm stability is adequate.
