AMC1306E05: Clock Noise Caused by High Frequency Switching

Francis Jiang

Part Number: AMC1306E05

Tool/software:

Hi Team,

AMC1306 need an external clock for modulating, such as 5MHz. But in digital power, the high frequency power FET will cause a big noise to the signal. So shall we have any reference design or suggestion for the clock layout? Or other useful method to reduce the impact cased by switching noise? Thanks in advance.

BRs,

Francis

Hi Francis,

Is this question related to your previous question on the AMC1306E05? AMC1306E05: Setting time & Latency time Questions - Data converters forum - Data converters - TI E2E support forums

Are you already following the e-meter design? Or is this a difference project? What does their current schematic/layout look like that they have tried? Please let me know so I can better support.
