The DSC400-1111Q0081KI2 packs four independent LVCMOS clock outputs into a single 5.00 mm × 3.20 mm 20-VFQFN package — replacing up to four discrete crystal oscillators and cutting the BOM count for multi-rail clock trees. The MEMS resonator gives it better shock and vibration immunity than a quartz-based XO, and the wide 2.25V–3.6V supply lets it run off either a 2.5V or 3.3V rail without an extra LDO.
The device outputs four LVCMOS clocks: 27 MHz, 50 MHz, 25 MHz, and 12 MHz.
It accepts a supply from 2.25V to 3.6V, covering both 2.5V and 3.3V rails.
