[time-nuts] XOR Mixers

There is a nice XOR mixer in the 9046 PLL  chip. Also a dual F/F mixer. Don't use other versions of the 4046. They have detector dead spots. 

You also have the advantage of being able to use them with signals from about 100 mV to 5V. 

I haven't used the chip for the purpose mentioned.

You might be surprised by the noise floor of an XOR run at 125 KHz. They are quite good at that low a frequency. 


Engineering is the art of making what you want from what you can get at a profit.
