7 Conclusion

Multiplexing FPD-Link is a viable answer for increasing the number of peripherals without necessarily increasing the number of deserializers. This method can provide a more space-efficient and simple implementation for systems with an odd number of mutually exclusive sensors. Additionally, multiplexing reduces the need for CSI-2 ports on the processor, a common limitation.

The multiplexing scheme does increase the insertion loss which can be offset according to user implementation with cabling choices. In terms of link margin and return loss, the multiplexed FPD-Link SerDes scheme is comparable to the non-multiplexed counterpart.
