Thanks

Now please make the mods in post # 1382

Then do the mods in my previous post, use RV7 to adjust to the center frequency.

Then you should see:

1. The pulse train at U4 pin 13
2. steady logic "0" at U8 pin 4
3. no light in D6

And this should be maintained, even though you dial RV7.

Please replace R15 to 4K7, and connect to U7 pin 11 instead of U8 pin 4.
Now D6 should indicate locked OK.

Sorry, sorry

MOD 1415#1: Connect the wire going to U6 pin 3 to U4 pin 4, being the only connection to U4 pin 4

Should have been

MOD 1415#1: Connect the wire going to U6 pin 3 to U4 pin 9, being the only connection to U4 pin 9

I must double check next time.

answer to Q1417#1:
U4 pin 4 152 kHz at duty 50% 5V SS
U4 pin 3 4764 hz duty 50% 4V SS
D6 on
U4 pin 5 (INH) constant 0V
U4 pin 2 5V SS rectangular
U4 pin1 5V SS variable frequency around 4763 hz duty 90%
U4 pin9 2 V with spikes down to 0.6V at around 4400 hz

sorry for the delay, I had to repeat the measurement for pin 9.

Thanks,

I just realized that we use phase comparator 2 output to feed R12+13, C10.

Q1421#1: By SS do you mean Steady State ?

MOD 1421#1 Please make fixed resistors R12=400Kohm (or 390Kohm), R13=10kohm, C10=10nF Or what you need to make it work, but R13=10kohm is mandatory.
When running we should see a stable voltage on C10 near 2.5V with less than 20mV ripple assuming the center frequency is set right.

MOD 1421#2 Connect R12 to U4 pin 2 instead of U4 pin 13.

answer to Q1421#1: No SS = pp = peak to peak (lowes voltage to highest voltage)

now I do MOD1421

"Answer to MOD1421#1: Voltage at C10 = 1.3V with 50mV ripple"

At what frequency ?

Definition of the PhaseLockedLoop "locked" condition:

1. Phase difference between U4 pin14 and 3 are close to zero all the time.
2. C10 voltage is a DC voltage with low ripple voltage.
3. Frequency at U4 pin 4 is stable close to the "resonance" frequency of the tank circuit.
4. U4 pin 1 pulsing at VCO frequency, so D6 is on.

Q1425#1 Do you have the lock condition now. ?

[bussi04]

Addition to MOD1421#1

addition at point C10-R13 the voltage is 2.5V with positive spikes up to 3.8V max at the falling edge of U4 pin3

Hi Bussi.

I think we are quite close now.

May I suggest you take a copy of your project directory with diagram version 0.5.

In the diagram, rename the version to SM test 0.1 and make the diagram up to date, as I suspect my picture of the PCB you have is not right, especially around the R12, R13, C10 connections.

Then we can empty the MOD log when you have posted me the diagram only. You can delete .net and .brd from the project zip file to reduce the size.

Lets have an updated diagram before we proceed. See my previous post (remember preview and scroll down before submitting a post as a time saver).

Do you have some spare 4046 ?

yes, I have 2 more 4046 from Texas Instruments and one HEF4046.

Now I do the update of the scheme.

From what I have seen so far, I think VIC replicators should take a look and get an understanding of what Armagdn03 shows in the oldest 5 videos.

Without that knowledge the PLL IC 4046 will IMO be a tough master to conquer.

Thanks Andrew for these very instructive videos:
