The Enable/Disable pin lets the system shut down the oscillator output when the clock is not needed, dropping the 22 mA max supply current to near-zero in sleep mode — useful for battery-powered or duty-cycled equipment.
It outputs a 33.3333 MHz CMOS signal, which is a standard logic-level square wave compatible with most MCU and FPGA clock inputs.
The operating supply range is 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V nominal rails without external regulation.
Yes, the base resonator is MEMS rather than quartz, which provides improved shock and vibration tolerance and faster startup compared to traditional crystal oscillators.
The Enable/Disable pin gates the output: when de-asserted, the output goes into a high-impedance state and the supply current drops from the 22 mA maximum to near-zero, saving power in sleep or standby modes.
Rated for -20°C to 70°C ambient, which suits commercial, indoor, and office equipment but not extended industrial or automotive environments.
