3.6 Serializer

The design uses a DS90UB953-Q1 FPD-Link III serializer to establish a high-speed connection to a deserializer link partner board, like the DS90UB954-Q1EVM. The diagnostic features of the FPD-Link III devices are used to determine the impact from the pulsing LEDs on the high-speed FPD-Link channel performance.
