DS90UB971-Q1: DS90UB971-Q1&DS90UB9702相关问题

Part Number: DS90UB971-Q1

Regarding TI serializer 971 and serializer 9702, please help to answer the following questions:

① About pin mapping, map pin gpio1 or gpio2 from end 971 to end 9702. According to the configuration in the specification, the input gpio1 of end 971 is high after the configuration, but the gpio1 level of end 9702 is always low, indicating that the mapping fails.The following is my configuration, please also help to check or verify on your EVK whether my configuration can be mapped successfully.

0 x30, 0 xe, 0 x96, 0 x808

X33 0 x30, 0, 0 x01, 0 x808

X7a 0, 0 x4c, 0 x01, 0 x808

0 x7a, 0 x11, 0 x21, 0 x808

X7a 0, 0 x59, 0 x01, 0 x808

② Help to provide detection of 971 and 9702 device status registers.So far, I've found 0x52 and 0x53 on end 971.Only the 0x04 register was found on the 9702 end.At present, there are few registers detected from the 9702 end, and it is impossible to detect the status of link data.For example, check the forward and reverse link status, video link status, and data error information.Please also help inform which registers to detect.

③ The client has a PRBS that requires the detection of the link, and the specific information and detection method are not found in the specification.Please also provide the generation and detection methods of PRBS.

④ The current temperature of 971 and 9702 can be read and converted.I would like to ask if there are 971 and 9702 about their own temperature detection, such as the way I set the junction temperature and report an error if it exceeds this junction temperature.These are also convenient for production line inspection and are more suitable for production lines than temperature conversion.Please also help to see if there is such a way, if so, please help to see how to achieve.
