Design Concepts
1

Hi,

May be this is not new for advanced users.

This XR-2206 Monolithic Function Generator is very usefull to use with analog out module, for example to control 3x XR-2206.

Low-Sine Wave Distortion, 0.5%, Typical

Excellent Temperature Stability, 20ppm/°C, Typ.

Wide Sweep Range, 2000:1, Typical

Low-Supply Sensitivity, 0.01%V, Typ.

Linear Amplitude Modulation

TTL Compatible FSK Controls

Wide Supply Range, 10V to 26V

Adjustable Duty Cycle, 1% TO 99%

Waveform Generation:

Sweep Generation

AM/FM Generation

V/F Conversion

FSK Generation

Phase-Locked Loops (VCO)

FM OPL3 and SID are hard to find parts, so this XR are too cheap and easy to find.

Any inputs are wellcome, let´s do it.

There are already myriads of VCO designs using the 2206 and 8038 out there.

Just hook em up with a MB-CV and be done with it.

Hey AC, if you are looking for an YMF262 and just one YAC512, I can sell for you an old SB 16 ISA.

I was planning desolder them for my future Midibox FM, but as I’m walking with turtle steps even in my mb64 project, there is no problem sell this board for you.

As you are from Brazil too, the shipping will be easy and cheap.

Send me a private message if you want this board.

PS: The board is working fine. It was tested.

i have one of these xr-2206 chips sitting here, i was wondering this very same thing… can we hook one up to a midibox core and build some synth software for it? (or should i build the function generator i had planned on building with it?)

hmmmm…
