This is the IC that was indicated to me as being a good place to start, in addition to this I have been doing a lot of research about phase descrimination circuits in order to confirm that the frequency is within range for doubling before it is doubled.

Descrimination can be acheived with a 74LS123 and a 74LS74.

I am researching another IC ATM which is a standard LM componant which provides much the same capabilities as the Maxim as well as another IC which acheives the same result but in a somewhat easier fashion I.E no other componants.

Your input would be welcomed
