7.4.6.5.1 Short Transport Test Pattern

Short transport test patterns send a predefined octet format that repeats every frame. In the ADC12DJ4000RF, all JMODE configurations that have an N' value of 8 or 12 use the short transport test pattern. The N' = 8 short transport test pattern is shown in Table 7-59. The N' = 12 test patterns are shown in Table 7-60, Table 7-61 and Table 7-62 which cover different values of F and S. All applicable lanes are shown, however only the enabled lanes (lowest indexed) for the configured JMODE are used.
