Hi All,

Just a warning.  Check the Oscillator voltage on DDS modules.

I bought five AD8950 DDS  type II early on.  One had 3.3 volt version of the 125Mhz osc.  All others were 5v 125Mhz oscillators.

Cheers,
Will

Many 5V logic chips work with 3V logic Attached is a bi directional logic converter that works well

Dear All:

 

Is there a way to convert the output of a 3.3v CMOS oscillator to a 5v ?

 

I have read that the AD9851 can accept a sinusoidal signal dc biased to Vdd/2.

 

Can I bias a 3.3 volts cmos oscillator (Square wave) to Vdd/2 to use it with my AD9851 using a VDD of 5 volts?

 

Regards.
