Can PI47AVC164245LA / PI47AVC164245LA be used for 3.3V to 1.8V level shifting for a clock signal?
All the logic level shifters can be used for clock signal level shifting. Please ensure that the spec of the output duty cycle of the level shifter meets the clock application request. Using a 0.1uf and a 0.47uf capacitor at each of the VCCA/VCCB pins as close as possible for minimum jitter from the Vcc to the output.
