TLC2934

Amr Eltaher

Dear sir, I got the data sheet of of a phase and frequency detectr TLC2934. I can not find in the data sheet the minimum resolution of your device, i.e. What is the minimum phase difference between two signals that the device can detect?Thanks for your co-operation.

Hi Eltaher,

I have forwarded your request to the team that supports this product.

Hi Amr,

In a traditional PLL application, the phase error reaches a steady state - can you elaborate more on the specification you require?

Hi Gabe, Thanks for your attention. I have two sinusoidal signals with very small phase difference, i.e. 0.01 gedress or smaller. Can this IC detect it? If not, can texas instruments electroniics detect this very small phase difference? Thanks,

Hi Amr,

By detect, do you mean you wish to set some sort of limit where if the two phases are out of alignment by N degrees then a digital signal is triggered or do you wish to be able to correlate the degrees of mismatch to a voltage?

Hi Gabe, It is does not really matter. However, I prefer the solution of triggering a digital signal, if they are out of alignment by N degrees. The main point here is the accuracy of the electronic circuit. Hence, the question is: Is it possible to detect such small phase difference electronically? Thanks,
