Product details

322.265 MHz LVDS clock — MEMS, not quartz

The output is LVDS, so the signal is a differential pair that rejects common-mode noise — runs clean across a PCB with long traces or through a backplane connector. Supply voltage spans 2.25V to 3.63V, covering 2.5V and 3.3V rails without a separate regulator — the oscillator draws 32 mA max from the rail.

Temperature grade and deployment fit

Package and board layout note

Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the small footprint leaves room for the differential pair routing and the decoupling cap right at the supply pin.

Availability confirmed at RFQ.

Frequently asked questions

What is the frequency output of DSC1123CI2-322.2650?

The oscillator outputs 322.265 MHz as an LVDS differential signal.

What is the difference between DSC1123CI2-322.2650 and DSC1121?

The DSC1123 series outputs LVDS, while the DSC1121 series outputs CMOS. For a 322 MHz clock, LVDS provides a differential signal with better noise immunity over longer traces than a single-ended CMOS output.

Can I use DSC1123CI2-322.2650 as a replacement for a quartz oscillator?

Yes, it is a drop-in replacement for a quartz XO in the same 6-VDFN footprint and supply voltage range. The MEMS resonator eliminates the need for external load capacitors and is more resistant to vibration and shock than quartz.
