Hi,

For VOD, you can set CFG1 = R and CFG0 = 0. What is the pre-channel loss (between host and TUSB544) and post-channel loss (between TUSB544 and the Type-C connector?

Thanks

David

Hi David,

pre-channel loss (between host and TUSB544):~8dB

post-channel loss (between TUSB544 and the Type-C connector: the short channel is ~2dB,but long channel maybe ~10dB.

Thanks!

Hi,

Assume UEQ is for pre-channel, I would set it

UEQ1 = 1, UEQ0 = R or

UEQ1 = 1, UEQ0 = F

DEQ1 = R, DEQ0 = 0

Thanks
