Logic Array
n – 1
The logic array sends parallel data to the SERDES transmitter circuit
when the TXLOADEN signal is asserted. This signal is generated by the
high-speed counter circuitry of the logic array low-frequency clock’s
rising edge. The data is then transferred from the parallel register into the
serial shift register by the TXLOADEN signal on the third rising edge of the
high-frequency clock.
