I2S data in interface to Microcontroller

Hello Rama 

1.Is your application automotive?  If so,  we do not have 2:1 8channel auto grade device but we can  create this solution.

Using 2 sn3257-q1 devices and 1 TS5A23 157-Q1 device

Please check out this FAQ and provide feedback 

Thanks!

Hi Kameron,

Thanks for the clarification provided. However, i have continuous I2S digital data coming from external source. one solution we are thinking is to use DS90UB927Q-Q1 which is FPD III serializer and it has 4 I2S digital audio inputs, can i use this only for I2S data input and get Serialized Audio output which i can interface to MIPI Camera interface of Microcontroller and read the I2S data.

Rama

Hello Rama,

Understood and before moving with that solution I wanted to see if you could provide a schematic of your design?!

When you say eight i2s data do you mean that this picture is on of these data line? 

Please let me know!

Hi Kameron,

we are in concept study finding solution, let me have four I2S audio data only but no video data. can only audio data be serialized send output which i want to use as input to MIPI and read this data.

Thanks Kameron and i will look into the details, also. we want to use TMS 320C6727B DSP in which McASP signals are received. Data received are in PCM format  in which Audio data format is 24 bit left justified , here in the MCASP block it is received which is serial data pin and internally it has serializer and shows Receive Formatter ( Figure 4-25 MC ASP block diagram of TMS 320C6727B DSP datasheet). what does Receive Formatter do once serial data are received and placed in which block of DSP block ( Figure 1-1 DSP Block Diagram) and flow of DSP functions to process this data?

Hi Rama,

Expect delay in response due to Labor Day weekend. Please allow a day or two for response.

Hi Rama,

Please refer the below document for information on McASP general architecture and how the data flow happens from receiver unit and serializers.

Hope this helps.
