sir i am making a inverter circuit by using with AT89C51 mc but for this I actually X having frequency 11.0592mhz but unfornatelay i could not find in list. so please help me

Hi Asifbox1, Welcome to EasyEDA. If all you want to do is draw a schematic with an 11.0592Mhz crystal in it then either just place the XTAL symbol from the **EasyEDA Libs** or choose one from **More Libraries...** (do **Shift+F** in any editor canvas and search for 'xtal') and then edit the Model property (in the XTAL symbol) or the Name property (in the other symbols) to your chosen part. To edit the Model or Name, open the right hand **Properties** panel (using **Toggle right bar**: hover the mouse over the far right hand vertical blue strip). If you want to actually simulate an 11.0592Mhz crystal oscillator then please see this example: <https://easyeda.com/file_view_Crystal-oscillator-using-EasyEDA-quick-starting-crystal-model_a71jBTb5n.htm> The crystal symbol used in this example is XTAL from the **EasyEDA Libs**. Open the right hand **Properties** panel (using **Toggle right bar**: hover the mouse over the far right hand vertical blue strip) to edit the crystal parameters, which you will find from the crystal manufacturers datasheet. :)
