Product details

MEMS XO with LVCMOS output and ±50 ppm stability

The DSC400-0101Q0083KE1T is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering LVCMOS outputs at 45.1584 MHz and 49.152 MHz with ±50 ppm frequency stability over -20°C to 70°C.

Housed in a 20-VFQFN exposed-pad package measuring 5.00 mm x 3.20 mm with a 0.90 mm seated height, the DSC400-0101Q0083KE1T fits tight board stacks and benefits from a thermal via array under the exposed pad for heat sinking. Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails without an external regulator.
