We see that the DDC line frequency is 43kHz how is this frequency set is there way to change this frequency
With regards VIL and VIH for I2C ,
VIH = 1.19 - 5.5[V] High level
VIL = -0.3 - 0.8[V] Low level
According to I2C-bus Specification, version2.1, Section 15
VIH = 0.7VDD - (VDD+0.5)[V]
VIL = -0.5 - 0.3VDD[V]
And if Low signal with 1.5[V] then it is considered as H .
Is ADV7511 up with the specification of I2C .
