Product details

MEMS clock source with dual 80 MHz LVDS lanes

LVDS signalling keeps the edge rates clean across short PCB traces — useful when both clocks feed separate FPGAs or SerDes transceivers on the same board.

Supply range and package footprint

The supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails without an external regulator. The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via pattern under the pad for heat sinking — the datasheet layout recommendation should be followed to keep the junction temperature within limits.

Frequently asked questions

What supply voltage does the DSC400-0303Q0092KE1 require?

The supply voltage range is 2.25V to 3.6V, so it can run from a 2.5V or 3.3V rail without an additional regulator. The enable/disable pin allows the output to be gated without a separate clock buffer.

What is the output type and frequency of the DSC400-0303Q0092KE1?

It provides two independent LVDS outputs, each at 80 MHz. The dual-output architecture can serve as a reference clock for two separate devices, reducing component count.
