Frequency synthesis
I'm looking a nice simple preferably one chip solution to produce TTL level
frequencies up to 200KHZ from a serial signal. Doe's anyone have any
ideas ?

Texas Intruments has a VFC320, Voltage-to-Frequency and
Frequency-to-Voltage Converter, up to 1 MHz.

Use a MAXIM DAC to drive it:

They have over 120 serial DACS to choose from.
Sorry don't know of any one-chip solutions. But I bet there is one out
there.
Good Luck, Pete.
