1.6.1.5.2. Alternate Checkerboard Generator

The alternate checkerboard generator circuit consists of simple flip registers that serve as test sources for serial data links.

The output sequence of subsequent N-bits sample is generated by inverting the previous N-bits (counting from LSB to MSB) of the same data pattern at that clock cycle. The first N-bits sample from LSB of the data pattern on next clock cycle is generated by inverting the last N-bits sample on the MSB of the data pattern on current clock cycle.
