clock sharing between two ic

[bilgekaan]

Hello,
I want to use only one xtal to drive two different ic. ( HT92000 & HT9170 ).
In the reference schematic two 20 pf capacitors are connected to xtal for both two chip. I see in the holtek forum that , to use one xtal , x2 of first chip must be coupled with 30pf capacitor to x1 of second chip.
Do I have to remove 20 pf capacitors from xtal ? I need connection diagram.
Regards

In many cases you can simply daisy-chain clocks ..
