Hi,
I want to multiply two signals using a mixer. But i want to give clock a sign signal. I tried to do that but it shows an error signal attached with this message.
Please guide me how i can do this.
Looking forward for your reply
Best Regards

When you take a look into the mixer's datasheet, Input/Output Connections, you will see that LO is a digital signal and not an analog one. On page 2 is a picture showing how an Up Mixer works.
So getting a true analog product of the two signals will not be possible this way.

I want to Multiply my analog sine signal with clock, which should also be sine signal.

Yes Bob you are right. But I want to Multiply two signals. 1st is my message signal which is in analog form and the 2nd one should also be in analog form with same phase. How i can do this?
Is it really possible?
Looking forward for your reply.

If you need true analog then consider SAR >> DFB Filter >> VDAC as solution.
The Mult occurs in code or DFB

This all depends on analog BW needed and dynamic range and....

Thank you for your valuable reply.
Now, What i concluded is, i can only implement lock in amplification (Multiplication of two signals having same phase) in PSOC through digital signals?
This means i have to convert my input signals into digital form and then performs filtering and amplification stuff?
Am i correct?
Looking forward for your reply.

Thankyou so much for this.
I am not sure how i can control the phase through this approach.
Do you have any idea?
Best Regards
