Hi!
After reading nRF24L01 product spec, I'm really unsure: Spec. says: "The input signal should not have amplitudes exceeding any rail voltage." "rail voltage" it's means VCC (3.3V max)? Or it's means I/O voltage (5V max)?
I wonder to know is it proper to drive nRF24L01 chip by external clock source with voltage amplitude = 5V applied to XC1 pin? Ofcourse while nRF chip powered by 3.3V.
Thanks!
