JESD204C defines both short and long transport test modes to verify that the transport layers in the transmitter and receiver are operating correctly. The ADC12DJ5200SE has three different short transport layer test patterns depending on the N' value of the specified JMODE (see Operating Modes). The short transport layer is only used when control bits are not used. Otherwise, the long transport test mode must be used. ADC12DJ5200SE supports the long transport test mode for all N' = 16 modes, since these modes use control bits. The transport layer test modes are the same for 8B/10B mode and 64B/66B modes with identical N' values, since the transport layer is independent of the link layer.
