Operating from 2.25 V to 3.6 V, this oscillator directly interfaces with 2.5 V and 3.3 V logic rails without an external LDO — a clean clock source for MCU, FPGA, or SoC reference inputs.
No official second-source or pin-compatible cross-reference is listed.
The standby (power-down) function disables the oscillator output and reduces supply current to 95 µA max. This is useful for battery-operated systems that need to gate the clock during sleep to conserve power.
The frequency stability is specified at ±25 ppm over the -20°C to 70°C temperature range. This is typical for a general-purpose XO and provides adequate margin for most MCU and logic clock applications.
