Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an extra regulator.
When the standby pin is asserted, the oscillator stops and draws 95µA max from the supply — not a full shutdown, but low enough to extend battery life in intermittently powered designs. Active current is 35mA max at 50 MHz, typical for a high-speed CMOS output driving a moderate load.
Yes, it is a direct functional replacement for a 50 MHz quartz oscillator in the same footprint — the 6-VDFN package is standard. The MEMS resonator offers better shock and vibration tolerance, so it may be a drop-in upgrade in rugged environments, but confirm the pinout and supply voltage (2.25V to 3.6V) against your existing quartz part.
The standby (power down) function disables the output and reduces supply current to 95µA max. It is controlled by a dedicated pin — when asserted, the oscillator stops; when released, it starts up again. This is designed for systems that need to conserve power between active periods.
