The DSC1121CI2-050.0000 is a 50 MHz MEMS-based oscillator delivering a CMOS output from a 2.25V to 3.6V supply rail — one part covers both 2.5V and 3.3V clock domains without a separate regulator.
The 6-SMD no-lead package measures 3.20mm x 2.50mm with a seated height of 0.90mm — a standard MEMS oscillator footprint that drops onto the same land pattern as many quartz XO alternatives.
Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec. The CMOS output swings rail-to-rail, matching 3.3V logic levels directly.
This is the total stability including temperature, supply, and aging — adequate for most automotive CAN, LIN, and Ethernet clock trees.
Yes, the function is Enable/Disable. When disabled, the output is tri-stated and the supply current drops to 22 mA max from 35 mA max active.
