Measuring condition and procedure are the same as described in Note28,expect SG3 to 180MHz.
Input SG3 (50MHz) to pin42 only, set Input SW of IIC BUS to 0 and then measure the
waveform amplitude output at OUT(2).The measured value is called VOUT(2).On equal
terms set Input SW of IIC BUS to 1.And then measure the waveform amplitude output at
OUT(2)'.Crosstalk INCT1 is calculated by the equation below:
Measuring condition and procedure are the same as described in Note30,expect SG3 to 180MHz.
Similarly measure the waveform amplitude output at
OUT(5) when signal input only Pin37 and OUT(9)when signal input only Pin32
and calculate crosstalk
Input SG3 (50MHz) to pin40 only, set Input SW of IIC BUS to 1 and then measure the
waveform amplitude output at OUT(2).The measured value is called VOUT(2).On equal
terms set Input SW of IIC BUS to 0.And then measure the waveform amplitude output at
OUT(2)'.Crosstalk INCT2 is calculated by the equation below:
Input SG3 (50MHz) to pin42 only, and then measure the waveform amplitude output at
OUT(2,5,9).The measured value is called VOUT(2,5,9).Crosstalk CHCT1 is calculated by
the equation below:
Similarly measure the waveform amplitude output at
OUT(5) when signal input only Pin35 and OUT(9)when signal input only Pin30
and calculate crosstalk.
Measuring condition and procedure are the same as described in Note36,expect SG3 to 180MHz.
