It operates from a 1.8V to 3.3V supply rail, drawing 7.2 mA max during active operation and only 15 µA in standby (power-down) mode.
In an automotive ECU that sleeps between ignition cycles, this keeps the quiescent load below the battery-drain budget without an external load switch.
In standby (power-down) mode, the maximum supply current is 15 µA. This allows the oscillator to sit on a battery-backed rail without draining the cell during long sleep periods.
Yes, it is a form-fit-function replacement for a quartz-based XO in the same 4-SMD package. The MEMS resonator provides better shock and vibration immunity than a quartz crystal, and the CMOS output is directly compatible with most clock inputs.
The frequency stability is ±25 ppm, which includes variations over temperature, supply voltage, and aging. This is tight enough for most automotive and industrial serial-communication clocking without external trimming.
