Stratix Differential I/O Transmitter Operation
You can configure any of the Stratix differential output channels as a
transmitter channel. The differential transmitter is used to serialize
outbound parallel data.
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.
