hi team,
the spec of I2C VIL of LM5064 shows the maximum value is 0.9V, it is an DC limitation or peak AC max limitation?
We find there is an high frequency noise in the I2C line and max ViL voltage is 1.1V for very short time(lower than 10ns level).
Does it have digital filter within LM5064? so that we can blank such a short higher voltage spike? thanks
thanks.
Hi Avishek,
Could you help confirm the TF,TR time 300ns is for 400KHz speed? If for 100kHz speed, does it can relax to 1000ns? because we find that when we add a filter cap, the TF/TR will be prolong to 600ns, which exceed the spec.
thanks.
Hi Kelly,
300 ns is for 100 kHz and 400 kHz bus speed. Rise and fall time should not exceed 300 ns. The pull-up resistance value can be reduced a bit to reduce the rise and fall times.
