It belongs to Microchip's DSC1101 series and is aimed at applications needing a precise clock source in a small footprint — think Ethernet PHYs, FPGAs, or high-speed serial interfaces where a quartz crystal would require additional load caps and a longer startup.
Supply voltage range and operating temperature
The part operates from 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V logic rails without an external regulator. The 6-VDFN exposed pad package (7.00 mm x 5.00 mm, 0.90 mm seated height) requires a thermal pad on the PCB for heat dissipation — a standard via pattern under the pad is sufficient for most layouts.
