Hi team,
we have question about REF_CLK amplitude. the VDDIO is 3.3V, can we use 1.8V oscillator as REF_CLK input?
in the datasheet, when VDDIO=3.3V, the REF_CLK VIH is 2V~VDDIO.
but, in the table 7-3, only show the range of REF_CLK is 800mV ~VDDIO.
we are confused about this ? which one is correct? can we use 1.8V power oscillator when VDDIO is 3.3V?
Thank you
