MEMS oscillator with two fixed clock outputs
The DSC400-0101Q0115KE1 is a MEMS-based XO (Standard) that replaces a pair of quartz oscillators with a single 20-VFQFN package — it outputs 12 MHz on one rail and 3.072 MHz on the other, both LVCMOS. Supply voltage spans 2.25 V to 3.6 V, so it runs off a 2.5 V or 3.3 V rail without an extra regulator.
Package and board-fit details
Housed in a 20-VFQFN with an exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height — the thermal pad needs a via pattern under the package to conduct heat to the inner ground plane.
