SN74LVC1T45: output jitter and oscillator converter

Part Number: SN74LVC1T45
Other Parts Discussed in Thread: SN74AXC1T45

I have an 3.3V oscillator (LVCMOS), I need to convert to 2.5V clock (~63MHz)

1. can I use this device?

2. what will be the output jitter (addative I guess)?

    1. Yes. But the SN74AXC1T45 is optimized for the lower voltage that you are using.

    2. < 1 ns typical, but there is no guarantee. (To minimize the jitter, use a fast translator. The AXC is fastest.)
