As shown, I don't understand why the two of the clock input? If according to the figure 2 pin is introduced, the XIN and XOUT vibration can be used as crystal clock input and can be used as a differential clock input, it adopts REF_P and REF_N what's the difference the clock input to use? Hope the great god glad!!!!!!

Used for low power consumption,

CodePudding user response:

1, crystals, use crystals provide clock
2, should be positive and negative differential input, for such as AD conversion of the analog input, other functions depends on the manual

CodePudding user response:

This is a chip circuit, the possibility of alternative
At the time of design, have a plenty of to each chips a boost for the source, not the clock generator;
Some design is to use a crystal up the clock source for the clock generator, again by the clock generator to generate the clock signal supply each chip,
Clock generator can better handle clock synchronization problems, so the application more specification
