I wanted to replicate this pcb: https://github.com/consolesunleashed/sony-playstation-multi-output-frequency-oscillator
The gerber files, bom and hex for the eeprom all are there. But I don't know how to program the hex to the CDCE925PWR. There is the official programmer CDCEL9XXPROGEVM but that is too expensive for just one time use.
Here is the backside of the pcb from gerber:
There are SCL and SDA points on the pcb and the datasheet talk about I2C support.
Datasheet: https://www.ti.com/lit/ds/symlink/cdce925.pdf?spm=a2g0s.imconversation.0.0.17993e5fIrszCt&ts=1715105157124
See chapter: 9.3.3 SDA/SCL Serial Interface
I have an XGecu T56, there seem to be no support for that clock chip. Is there a way with my or any other cheap general purpose flasher to program that chip?

I was going to suggest a universal programmer. Then I noticed that you've already tried that. Since CDCE925PWR is manufactured by Texas instruments, I think it's better to ask them to suggest a compatible programmer. They must have one.

Texas Instruments has their own one, the CDCEL9XXPROGEVM. But that alone costs over 100USD. I better want to invest to a device that is more multipurpose.

Protocol is standard so use Arduino.

I have found some alternatives now, one is a DIY board based one: https://circuit-board.de/forum/index.php/Thread/18016-DFO-Dual-Frequency-Oscillator/
And another Raspberry Pi based: https://github.com/nostalgic-indulgences/cdceprog
