I like to build a sin wave generator
External clock input, the generator is phase synchronized with an external clock signal,
Set a programmable phase delay to the external clock signal
A sine wave output, frequency between 200MHz and 400MHz
Very stable output power (min. 0 dBm)
Very low harmonic output (more than 60 dBc, ideal 80 dBc) and low spurious output
jitter < 200 fs (1kHz-20MHz)
good thermal stability
Is a DDS a solution?
The AD 9739A FMC Card?
All suggestions are welcome.
Thanks for the input.
