I just finished OCXO/TCXO clock module installation for OPPO UDP 203.


The result is wonderful . More detailed and  vivid picture and trueful digital sound .


0.01 PPM class Ocxo clock is used for 27 MHz system clock 

 and 2.5PPM class TCXO clock is used for secondary OPPO ARM chip operation.


It needs 4 V AC for supplying 3.3V DC.

So I ordered special transformer which has 4V and 

6V AC tap( later it will be used for supplying 5V DC to ESS9038 PRo featured DAC board).
