I think we are missing something fundamental here. In the CDP-101 it calls the shots. You march to the beat it sets. It doesn't care that you have a 16.9344MHz crystal. Either you give what it needs or you track what it gives.

The pictured clock generates 16.9344 and 4.2336. I don't understand which fundamentals are missing.
Clox is 4.2336.

The CDP-101 is not Philips therefore the circuit has to be adapted to suit the Sony. The CDP-101 doesn't care about 42336 or 169344. The system clock in the Sony is 8.6436MHz and that is what must be accounted for.
Are you in the wrong thread or is IC SN74LS624N pin 5 ( A813 XTAL ) not a clock output of 8.64MHz, feeding the CX7934 at pin 16?
Please. check the linked CD-200 service manual pages 84 and 86.
And i´sn't 8.64MHz the base frequency the CDP-101 runs on? See CDP-101 SM.

Your grand plan is to run the DIT off the 'superclock' and remove the crystal from the Sony and replace it with a VCO circuit? Must be the great leap backwards . Don't think there will be clones on eBay any time soon. Once again: The grand plan is from you and was originally executed by Philips.
The "Superclock" is just a byproduct, it lays in a box for a decade.
So instead of being sarcastic present the math behind the leap backwards.
