Figure 84. Test Mode Insertion Points
7.4.5.2 PRBS Test Modes
The PRBS test modes bypass the 8b, 10b encoder. These test modes produce pseudo-random bit streams that
comply with the ITU-T O.150 specification. These bit streams are used with lab test equipment that can self-
synchronize to the bit pattern and, therefore, the initial phase of the pattern is not defined.
The sequences are defined by a recursive equation. For example, Equation 10 defines the PRBS7 sequence.
y[n] = y[n – 6]
⊕y[n – 7]
where
bit n is the XOR of bit [n – 6] and bit [n – 7], which are previously transmitted bits
(10)
Table 39 lists equations and sequence lengths for the available PRBS test modes. The initial phase of the
pattern is unique for each lane.

7.4.5.3 Ramp Test Mode
In the ramp test mode, the JESD204B link layer operates normally, but the transport layer is disabled and the
input from the formatter is ignored. After the ILA sequence, each lane transmits an identical octet stream that
increments from 0x00 to 0xFF and repeats.
7.4.5.4 Short and Long Transport Test Mode
JESD204B defines both short and long transport test modes to verify that the transport layers in the transmitter
and receiver are operating correctly. The ADC12DJ2700 has three different transport layer test patterns
depending on the N' value of the specified JMODE (see Table 19).
