What is the maximum speed of FSK/PSK switching of AD9835 DDS?

przemyslawuk on Aug 27, 2012

Hi,

Does anyone know is the maximum bitrate of FSK/PSK switching of AD9835 and similar DDS IC's?

Assuming max MCLK how often can I switch the FSEL/PSEL inputs?

I read from he datasheet that there is about 6 clock cycles pipeline delay on these inputs, but can I change the

state of these inputs faster than that to get the FSK/PSK modulation ?
