Active MEMS XO with quad HCSL/LVPECL outputs
The DSC400-4244Q0069KE1 is a MEMS-based XO (Standard) from Microchip's DSC400 series, producing four differential clock outputs: two at 100 MHz and two at 161.132813 MHz, selectable between HCSL and LVPECL logic families. It operates from a 2.25 V to 3.6 V supply rail, covering both 2.5 V and 3.3 V system power domains without an additional regulator.
Package and layout: 20-VFQFN with exposed pad
Housed in a 20-VFQFN Exposed Pad package measuring 5.00 mm x 3.20 mm with a 0.90 mm height, the exposed pad requires a thermal via pattern on the PCB to manage heat and provide a low-impedance ground return.
