AD9835: FSK transmitter

GenevaCooper

Q

AD9835: I want to realize a frequenzy agile FSK transmitter (5 to 21 MHz,
frequency hub of +-50 or 67 kHz). It seems that the AD9835 can do this. Is that
correct an can this FSK be simulated with the evaluation board?

A

In practice you can a DDS…

AD9835: DC offset cancelation

GenevaCooper

Q

I need to generate test tones from the sub-Hz range up to mid-audio (0.1Hz ..
4kHz) for which your AD8935 seems perfect although you market it primarily as
an RF device. For kHz freqs, AC-coupling the output is no problem, but around
1Hz and below…
