Hello.

Another board provided a 66.67MHz 1.8V LVCMOS clock through cables. Now I need to convert to 3.3V LVCMOS for CPLD as the system clock. Is SN74AVC4T245RSVR OK?

Hi Xujunfeng,

Yes, AVC is okay for 66.67 MHz 3.3 V outputs, thanks.

Best Regards,

Michael.

Hello, I am mainly worried that the clock duty cycle and jitter will increase too much, may I ask whether this model has such data?

Hi Xujunfeng,

Please note that the datasheet specs 190 MHz. Hence, no concerns for 66.67 MHz.

For models available, please see SN74AVC4T245 IBIS Model (Rev. B), thanks.

Best Regards,

Michael.
