Product details

MEMS XO with four independent outputs

Supply range and stability for mixed-voltage boards

Housed in a VFQFN with exposed pad (5.00 mm × 3.20 mm, 0.90 mm height), the thermal pad under the package needs a via array to the ground plane for proper heat sinking. The pad also serves as the only GND connection — ensure the solder paste coverage is even to avoid tilting during reflow. Rework with hot air is straightforward if the board has adequate via thermal relief — the MEMS die is less sensitive to reflow profile than a quartz crystal.

Frequently asked questions

What are the exact output frequencies and signal types of the DSC400-3331Q0098KE2?

This XO provides four outputs: one at 12 MHz and three at 50 MHz. Each output can be configured as LVCMOS or LVDS, giving flexibility to drive both single-ended and differential clock inputs on the same IC.
