PRODUCTION DATA.
The long-transport test mode is used in all of the JMODE modes where N' equals 16. Patterns are generated in accordance with the JESD204B standard and are different for each output format as defined in Table 19. The rules for the pattern are defined below. Equation 11 gives the length of the test pattern. The long transport test pattern is the same for link A and link B, where DAx lanes belong to link A and DBx lanes belong to link B.
Table 42 describes an example long transport test pattern for when JMODE = 10, K = 10.

The pattern starts at the end of the initial lane alignment sequence (ILAS) and repeats indefinitely as long as the link remains running. For more details see the JESD204B specification, section 5.1.6.3.
