We're considering external CMOS oscillator.

Could you please see attached file.

Is this device possible to use with Figure 136. for CLK.

Hi Shinichi,

Yes, this will work without any issues. Also, please note for best performance while using this single ended clock configuration, place the 0.1uF capacitors as close as possible to the clock input pins (18,19).
