Hi,

I want to understand if this chip can handle a frequency of 40MHz LVCMOS clock on its input?

The datarate says 500MBPS so i am assuming the frequency it can handle is nearly 500MHz for 1.8V to 3.3V.

Is this correct? the datasheet talks about 10MHz frequency only.

thank you for the reply.

thanks

40 MHz = 80 Mbps; the chip can easily handle this.

what is the application voltage levels in your case?

For 1.8 <> 3.3V, 40Mhz can be handled without issues.

Hi,

Thank you for reply. The voltage conversion is from 1.8V to 3.3V.

Also as just a buffer with both vcca and vccb,=1.8v

Thanks

Hi,

Thank you for replying. How are you relating 80Mbps as 40MHz and not as 80MHz?

Thanks

A 40 MHz square wave has a cycle length of 25 ns. In this cycle, there is a high and a low pulse, with a pulse width of 12.5 ns. Each pulse corresponds to a bit.

Ok. Thank you I understood

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
