Recently in the use of multi-channel 8209 d power chip, chip agent reference circuit diagram is given, and 6 8209 share a crystal inside, in the use of oscilloscope waveform of view crystals pin, to find the most close to the chip and the vibration of high voltage, the farther the crystals is, the less the input voltage, do not know to this have any effect on the normal work of the chip?

CodePudding user response:

I understand it, crystals is a read-only devices, as long as the crystal oscillation circuit is complete, no matter how your chip, software, hardware configuration, will not affect the function of crystals, since the function of the crystals is not affected by external, that share is no problem in theory, as for the voltage, you can hang up two chips, for example, have a try first,
