 		 #163966 - 4 pins oscillator
Responding to: ???'s previous message
Jecksons Ben said:
Hai

I'm modified circuit.

Have problem.

At the original used 4 pins oscillator(4 pins XTal).The one with VCC,GND,2 pins out.
Since that kind oscillator didn't available here,I decided to change it with 2 pin Xtal.

Someone gave me advice..How to used 2 pins Xtal to became 4 pins oscillator(Xtal).
only 1 output used.

THank you very much
Best Regards
Jeckson Ben



Ben , When you look at the Crystal from the back that SMD one it has a chamfered edge at one of its pad now this and the diagonal one is the main connections for the MCU . The other diagonal one are GND .

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      
                              Just injected to OSC1 at HC08            01/01/70 00:00      
                                 have a look here            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      
                                                            without crystal            01/01/70 00:00      
                                                               Have you ever seen one anywhere?            01/01/70 00:00      
                                                               Give more information            01/01/70 00:00      
                                                                  I read it differently            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      
                                                                                 Before I posted            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      
            Very Important Question !!            01/01/70 00:00
