What this MEMS oscillator brings to a clock tree
The DSC1101BI2-050.0000: The MEMS resonator gives faster startup than a quartz crystal — typically under 5 ms — and better shock/vibration immunity, which matters for equipment that sees frequent power cycles or mechanical stress. Supply voltage spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail without an external LDO.
Standby mode and disable current
The Standby (Power Down) function drops the supply current to 95 µA max when the enable pin is pulled low — the output goes high-impedance, letting the downstream clock inputs float or be pulled to a safe state. Active current is 35 mA max at 50 MHz, so the standby savings are meaningful in battery-powered or duty-cycled designs where the oscillator runs only during active processing windows.
It remains qualified for new designs and production builds.
