The 1.8V–3.3V supply range allows direct connection to common logic rails without a level translator, and the standby (power-down) function reduces current draw to 15 µA max when the clock is not needed.
Active current of 7.2 mA max is roughly half what many 40 MHz quartz oscillators draw, making this part a better fit for battery-powered gateways or sensor nodes that keep the clock running continuously.
Yes, it is a drop-in electrical replacement for a 40 MHz quartz XO in the same 4-SMD, no-lead package. The MEMS resonator provides faster startup and better vibration immunity than quartz, and the ±10 ppm stability matches many quartz specifications.
It is an XO (Standard) type oscillator with a CMOS output. The CMOS output is compatible with most digital logic families without external level shifting.
