Part Number: DS90UB953A-Q1
We are analyzing if we can change the camera serializer from 9023292AA (DS90UB953TRHBRQ1) to 9024567 (DS90UB935TRHBRQ1).
For that I performed the below anaylsis.
Could you please review the same and also help us with point no. 4.b ,6, 8 and 9?
| Sr No. | Comparison Considerations | Comment on difference between 953 and 935 |
| 1 | Drop in replacement? | Yes |
| 2 | Register differences? | No difference in the registers that we are currently using. |
| 3 | Clocking differences? | Internal AoN clock available. Note: Non-Synchronous Internal Clock, OSCCLK_SEL = 1 option not available in 935.We are not using this one. |
| 4 | Bandwidth? | Lower as compared to 953. 953: 3.328 Gbps CSI-2 Bandwidth 935: 2.528-Gbps CSI-2 Bandwidth |
| a. H and V blanking is compatible? | Compatible | |
| b. Frame Sync is compatible? | ||
| 5 | Imager Compatibility? | |
| a. Same frame rates? | Supports 30fps. | |
| b. Same colour depth? | Yes | |
| 6 | Configuration changes? | |
| a. Project specific changes that need to be done? | ||
| b. Can we reuse the same WB and AE values? | ||
| 7 | Overall power consumption? | |
| a. Power consumption | Low (0.25 W typical) power consumption 0.03 watts less than 953. |
|
| b. Supply voltage | Same - Single 1.8-V power supply | |
| 8 | Changes in SNR? | |
| a. Imager to seralizer | ||
| b. Serializer to ECU? | ||
| 9 | Changes in EMC emissions? (might not be possible to get this info) | |
| a. Imager to seralizer | ||
| b. Serializer to ECU? | ||
| 10 | ESD compliance common? | Common |
| 11 | PoC specs identical? | Identical |
| 12 | Supported colour encoding formats? | |
| a. 100% overlap? | 100% Overlap | |
| 13 | Diagnostics overlap? | 100% Both support Serializer Status and Monitoring, FC diagnostics and BC diagnostics.Registers used are also same. |
| 14 | FIxed Color Patterns. a. Are they same? |
Yes it’s the same.Both support 8-bit, 10-bit, and 12-bit pixel formats. Same number of color bars and blocks are supported. |
| 15 | Compatibility with deserializer | Though datasheet doesn't list 962 in compatible deserializers. Got confirmation from TI that it is compatible. |
