Kevin,

As noted in the featues section, the max frequency supported by this device is 380Mbps at 1.8 to 3.3V translation.

Please share the application usage for this device, IO translation levels, and other info if possible.

Dear Shreays,

But do you know how to transfer Mbps<==>Hz ??
The customer want to use it for 25MHz. But we are not sure what is the relationship between Mbps and Hz.

Kevin,

1Hz = 2bps.

So 25Mhz is 50Mbps.

Hi Kevin,

You can refer to a generic google search on thorough explanation.
In terms of digital data transfer, a square wave can have 1 bit transferred at the rising edge and another at the falling edge, so 2 bits.
