What does this MEMS oscillator do on the board?
The DSC2011FI2-F0035T is a MEMS-based XO (Standard) that generates two independent CMOS clock outputs from a single silicon resonator — 25 MHz on output 1 and 16 MHz on output 2. Because the base resonator is MEMS rather than a quartz crystal, there is no start-up time penalty from a crystal's load capacitance; the oscillator is ready within microseconds of enable. The Enable/Disable function lets a GPIO or power-management IC gate the outputs, pulling the supply current from 32 mA typ down to 23 mA in disable — useful for power-cycled sensor nodes or multi-rail sequencing.
Which supply rails and temperature ranges fit?
Frequency stability is ±25 ppm across the full temperature and voltage range — tight enough for a 100BASE-TX Ethernet reference or a Cortex-M PLL without needing a TCXO.
Package and board layout considerations
Tape & Reel (TR) packaging is standard for automated pick-and-place; the small footprint leaves room for decoupling caps and signal routing on dense mixed-signal boards.
