The supply voltage spans 2.25V to 3.6V, so the oscillator runs directly from a 2.5V or 3.3V rail without an external LDO. The CMOS output swings rail-to-rail, which means it drives standard logic inputs (3.3V LVCMOS, 2.5V HSTL) with no level translation.
The 6-VDFN exposed-pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm.
Yes. The supply voltage range of 2.25V to 3.6V includes 3.3V directly. The CMOS output at 3.3V swings rail-to-rail, so it drives 3.3V LVCMOS logic inputs without a level shifter.
Within Microchip's DSC1121 series, other frequency variants (e.g., 125 MHz, 50 MHz) share the same 6-VDFN package and pinout. For a direct 100 MHz replacement from another manufacturer, the MEMS-based SiTime SiT8208 series offers a similar footprint and electrical characteristics — confirm the Enable/Disable logic polarity and supply voltage range before substituting.
