I'd like to drive an Si5350 with a MEMS oscillator instead of a crystal for environmental robustness purposes. The Si5350 FAQ says that a CMOS input may be used instead of a crystal so long as the input does not exceed 1 Vpp. The MEMS oscillators are only available in 2.5V - 3.3V outputs.
Is a voltage divider an acceptable means of reducing the input reference, or is there a better solution?
