Product details

409.375 MHz LVDS clock with MEMS resonator

Output is LVDS, which gives a differential signal with typical 350 mV swing into a 100-ohm termination — the common-mode rejection rejects ground bounce and supply noise that a single-ended clock would couple into the data path.

Frequency stability and supply range

Supply voltage spans 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails with margin — no external LDO is needed when the rail is within that window, and the enable/disable function lets the system gate the clock without a separate load switch.

AEC-Q100 qualification and package

Packaged in a 6-SMD, No Lead ceramic-composite package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the small footprint fits dense PCB layouts, but the 6-pad land pattern requires a soldering profile matched to the MEMS die's thermal mass for void-free reflow.

Frequently asked questions

How can I order the DSC1123CI5-409.3750 or check stock?

The DSC1123CI5-409.3750 is an active Microchip part. We source it through independent distribution — submit an RFQ with your target quantity, and we will confirm availability and pricing. Stock levels change daily; no live count is published here.

Is the DSC1123CI5-409.3750 compatible with a 3.3 V supply?

Yes. The supply range is 2.25 V to 3.63 V, so a nominal 3.3 V rail sits well within the operating window — no external regulator needed.

Does the DSC1123CI5-409.3750 meet AEC-Q100 standards?

Yes, it is rated AEC-Q100, covering the automotive qualification requirements for temperature, reliability, and ESD.
