Hi,
I have used SN65LV1023/SN65LV1224 serializer/de-serializer for transmitting I2S audio streams over a cat5 cable. The de-serializer is powered with the same cable although there is a delay (1s) in setting the \PWRDN pin high. The serializer always transmits even before connecting the cable to de-serializer.
I have noticed that in some cases, upon connecting the cable, either the serializer or de-serializer (or both) get damaged and stop working. I have followed all the recommendations in the datasheet where it even states the support of hot insertion of the de-serializer.
Any tips on what might cause this?
