TMDS181 VIL and VIH Parameter for HPD_SNK

Sadanori Kato

Hi,

The VIL and VIH parameter for HPD_SNK is mentioned on page 7 and page 11 of the data sheet.
However, these references are different. as below.
Could you please tell us which is correct ?

Page 7 :
VIH = 2V ~ 5.5V
VIL = -0.3V ~ 0.8V

Page 11 :
VIH = 2.1V(Min)
VIL = 0.8V(Max)

Best regards,

Hi Kato,

Vi-dc = -0.3V to 5.5V is the DC voltage you can have in such pin.
vil(max)=0.8V
Therefore Vil range:
VIL = -0.3V ~ 0.8V
There is no problem here

on page 7, there is a typo it should be Vih=2.1(min)
Therefore Vil range:
VIH = 2.1V to 5.5V
