Hi.

I'd like to control by using the SPI port of AD9910. But I'm confused with the below specification.

 

AS you can see the Minimum SCLK clock pulse width is 4ns then we know 1 period is 8ns.

then the maximum frequency is 125Mhz.

 

But I'm confused that between maximum SCLK Frequency's Typ 70Mbps and 125Mhz.

 

What does SCLK Frequency's Typ 70Mbps mean?
