The modules produced 2 Signal out which have high resistance output.
The original schematic only get 1 pin out.

Since the Xtal needed "something buffered" to produced real signal oscillator.

Must I used something like TTL/CMOS chip to produced signal?

Thank you

Change 4 pins oscilator with 2 pins XTal            01/01/70 00:00      
   You mean "how to make an oscillator"?            01/01/70 00:00      
    4 pins oscillator            01/01/70 00:00      
      Are you sure            01/01/70 00:00      
         Yes,replacing osc module with Xtal only            01/01/70 00:00      
            Can you post the schematic ?            01/01/70 00:00      
               looking..            01/01/70 00:00      
                  No the complete one including MCU etc as            01/01/70 00:00      
                     controller model should be enough            01/01/70 00:00      
                        Schematic would be even more helpful            01/01/70 00:00      
                           Good point            01/01/70 00:00

                                    miss the point            01/01/70 00:00      
                                       You need an oscillator, which can be strobed?            01/01/70 00:00      
                                          I'm looking            01/01/70 00:00      
                                             Bigger            01/01/70 00:00      
                                                10 Mhz            01/01/70 00:00      
                                                   I guess...            01/01/70 00:00      
                                                      bigger than osc.module            01/01/70 00:00      
                                                         DS1077 ?            01/01/70 00:00

                                                                     Original request seems to have been fixed-frequency            01/01/70 00:00      
                                                                        but he wants 5 or six pins ... Heaven only knows why ...            01/01/70 00:00      
                                                                           Phases or output-enable probably            01/01/70 00:00      
                                                                              When I am in a hurry ...            01/01/70 00:00      
                                                                                 Sounds like a good idea            01/01/70 00:00      
                                                                                    I haven't found any so far ...            01/01/70 00:00

                                                                     got my point            01/01/70 00:00      
   oscillator v crystal            01/01/70 00:00      
      What microcontroller?            01/01/70 00:00      
         Sorry not MCS-51 it's freescale/motorola            01/01/70 00:00      
      Not tied directly to MCU            01/01/70 00:00      
         Tell us microcontroller            01/01/70 00:00
