For our new project, I are evaluating the DS90UB903Q-Q1/4Q SER/DES. I have already bought the Evaluation Kit. Both Ser/Des working very well.
But a few days ago, when I search on web some alternative, I found DS92LX2121/22 SER/DES. I read very well the two datasheets and the main differences that I found, are the max values of input PCLK support (43MHz vs 50Mhz) and data throughput(903 Mbps vs 1050 Mbps). It is correct? There aren't any other functional differences?
Please you can confirm that Built in Self Test (BIST) is only available in the Camera mode? There is none way to implement this test or a BER test in Display Mode?
Thank you very much

You are correct in that the two devices are quite similar functionally. In adition to the differences that you found, one of the biggest differences between the devices is in their qualification levels and guaranteed temperature ranges. The DS90UB905Q/4Q are intended for the automotive market, and as a result are qualified to the AEC-Q100 quality specs, and have a max temperature rating of 105C, while the DS92LX devices meet our standard industrial grade qualification level, and are guaranteed to a max temperature of 85C
In terms of functionality, both DS90UB903/4 FPD-Link III and DS92LX2121/2 Channel-Link III are the same. Channel-Link III is targeted for industrial/consumer applications whereas FPD-Link III is intended for automotive applications. Channel-Link III chipsets have a lower temp range but are extended frequency range. Alternatively, FPD-Link III chipsets are AEC-Q100 certified and go through a different production test flow.
As for BIST, it's available only in the Camera mode.
