I want to design a 66AK2L06 chip Schematic diagram and PCB diagram according to altium designer,but I can't find its CAD/CAE symbols from http://www.ti.com/,
it has so many pins, so it will be a very bad thing to draw these pins according to the datasheet, how can I get the the CAD/CAE symbols of 66AK2L06 from yours?
Then can you tell me what the difference is among 66AK2L06XCMS、66AK2L06XCMS2、66AK2L06XCMSA and 66AK2L06XCMSA2? Do they have obvious differences in performance, please give me a brief description. I am a beginner, I need some help, thank you very much.
