ZHCSFB7E august 2016 – march 2023 TUSB546-DCI
PRODUCTION DATA
The purpose of receiver equalization is to compensate for channel insertion loss and inter-symbol interference in the system before the input of the TUSB546-DCI. The receiver overcomes these losses by attenuating the low frequency components of the signals with respect to the high frequency components. The proper gain setting should be selected to match the channel insertion loss before the input of the TUSB546-DCI receivers. Two 4-level inputs pins enable up to 16 possible equalization settings. USB3.1 upstream path, USB3.1 downstream path, and DisplayPort each have their own two 4-level inputs. The TUSB546-DCI also provides the flexibility of adjusting settings through I2C registers.
