Hi TI guys,
we will use DS90UB927 communicate with DS90UB940,this case can be achived?and waht issue we need note?
how to config DS90UB927 this pad
Kailyn Chen：
Hello，first,the DS90UB940-Q1 is also backward-compatible with the DS90UB925Q-Q1, DS90UB925AQ-Q1, and DS90UB927Q-Q1 for PCLK frequencies ranging from 25 MHz to 85 MHz. Backward compatibility does not need to be enabled. When paired with a backward-compatible device, the deserializer auto-detects to 1-lane FPD-LinkIII on the primary channel (RIN0±).
As to the BKWD pin of DS90UB927, because 927 didn't need to be back compatible, it should be configured BKWD=0.
If BKWD=1 it means that 927 interfaces with 906/916.
