[sdiy] monolithic VCO chips for FM??

Haven't used it, just looking at the datasheet.

Only one waveform out at a time, no mixing. Choose between one wave at a
time (sine, tri, pulse) or use as a triangle core VCO with external shapers.

The doc mentions "sawtooth" a few times without revealing how to produce a
saw wave! Is the PDO output the key? Is PDO the quadrature output mentioned?
Tune in next time for more mysteries of the 038!
