Product details

MEMS oscillator at 33.3333 MHz — what drives the choice

Supply voltage spans 2.25V to 3.6V, so it works off 2.5V or 3.3V rails without a separate regulator.

It belongs in indoor equipment, office electronics, or appliances where the ambient stays above freezing and below a warm room. Not suited for outdoor telecom cabinets, engine bays, or unheated storage without climate control. The 6-SMD No Lead package (3.20mm x 2.50mm, 0.90mm seated height) is a standard MEMS oscillator footprint. Reflow profile follows JEDEC J-STD-020 for MSL; no special handling beyond normal moisture-sensitive-device bake requirements.

Product status is Active. The DSC1121 series is the base product number. The 'CE5' suffix denotes the ±10 ppm stability grade and commercial temperature range.

Frequently asked questions

What is the output type of DSC1121CE5-033.3333T?

The output is CMOS. It drives a standard digital load — typically a clock input on an MCU, FPGA, or PHY — without needing an external termination resistor.
