MK 109 Electronic Dice Kit

Hi - have build the kit - great no problems!
Could Velleman please mail me a circuit description for a student project report.
We would appreciate a general description of how the circuit works and choice of ICs used.
That would be really helpful.
Thanks :slight_smile:

Sorry, no circuit descriptions.

Ok thanks - for reply.

We were just wondering why the PLL IC was choosen - as only a part of the IC is being used. Any ideas?

Do you have the formula to calculate the frequency of output pulses from the VCO on pin 4? That woud be quite helpful. Thanks

Please check the datasheet of the IC.

It’s ok thanks - we’ve sorted it now.

Thanks for all your help. :smiley: :laughing:
