80 MHz MEMS clock — fixed frequency, no quartz
The DSC1030BC1-080.0000T is a fixed-frequency 80 MHz XO built on a MEMS resonator rather than a quartz crystal — the MEMS die is sealed at the wafer level, which gives it better resistance to shock and vibration than a quartz blank.
Active supply current is 5 mA typical at 80 MHz — a low-power figure for a MEMS oscillator at this frequency, which keeps the thermal budget small in a sealed 4-SMD package.
