DS90UB971-Q1: Forward channel and back channel

Hello Casey 

To get some basic understanding on below statement 

"The forward channel from serializer to deserializer carries high bandwidth video or sensor data, while the back channel is used to transfer lower bandwidth data like I2C, control, and GPO signals"

In the back channel can the GPIO data, I2C transfer or communicate both sides from Ser to Dser / Dser to Ser

 

in the sense either of Forward channel GPIOs or Backward channel GPIOs data Can be communicated to both sides (Ser to Dser and Dser to Ser) through the BCC ???

  • Hi Sandeep,

    It depends which way you are sending the GPIO. If you are sending from Des to Ser you will use the BC. If sending from Ser to Des it uses the FC. Please see section 6.3.6.4 Forward Channel GPIO and 6.3.6.5 Back Channel GPIO for further information.
