DS90UB971-Q1: Serializer GPIO data transfer

Sandeep Pinninti

Part Number: DS90UB971-Q1

How was the GPIO data transferring from serializer to deserializer, is it Through I2C register / Imager Embedded data Forward channel / or some other way ??

Hi Sandeep,

GPIO data from serializer to deserializer is passed through the forward channel.

Hi Sandeep,

Yes, please refer to Section 6.3.6.4 Forward Channel GPIO in the datasheet. This section will describe operation and recommended GPIO timings for each link rate as well.

Best,

Zoe

Could you please suggest me TI webpage or document, where i can read understand the complete data transfer CSI2 from imager to serializer FPD-link forward channel and back channel communication of with host ...could actually helps me a lot

Hi Zoe

I am sorry, i have the below revision datasheet

6.3 and 6.4 has looks the thermal information and electrical limitation

Correct me if i am wrong

Hi Sandeep,

Yes, this is the intended information. The DS90UB971 datasheet was revised in April of this year hence the differing section number. I recommend referencing the latest datasheet.

The following application can be used as a reference for system level design with FPD-Link devices: How to Design a FPD-Link III System Using DS90UB953- Q1 and DS90UB954-Q1

Please note this reference is written for FPD-Link III, not FPD-Link IV. Feel free to ask additional questions if needed.

Best,

Zoe

Hello Zoe

Will there be any difference for FPD link III to FPD link IV in terms of system level design

Hi Sandeep,

Yes, there will be differences in terms of system level design between FPD-Link III and FPD-Link IV devices. In regards to understanding the data transfer from serializer to SoC, FPD-Link III and FPD-Link IV will operate in the same manner.

Best,

Zoe
