DS90UB947-Q1: BCC delay and FC delay value

Peter Chen(ICP_FAE)

Part Number: DS90UB947-Q1

customer is asking the BCC delay and FC delay value come from.

i learned from datasheet, the BCC stand for bidirectional control channel and FC stand for forward channel. Can you support more detail description and how to do the value estimation.

HI Peter,

The values you highlighted should be approximately the same for the 94x series as well. If you would like to do a bench test, then you can hook up the i2c data line from both you SER and DES and monitor on the scope. Measure the start of your data transmission from SER and see when you receive it on the DES for FC delay. Do the reverse for BCC delay.
