Stratix Differential I/O Receiver Operation
You can configure any of the Stratix differential input channels as a
receiver channel (see
the incoming high-speed data. The input shift register continuously
clocks the incoming data on the negative transition of the high-frequency
clock generated by the PLL clock (
The data in the serial shift register is shifted into a parallel register by the
RXLOADEN signal generated by the fast PLL counter circuitry on the third
falling edge of the high-frequency clock. However, you can select which
falling edge of the high frequency clock loads the data into the parallel
register, using the data-realignment circuit. For more information on the
data-realignment circuit, see
on page
In normal mode, the enable signal RXLOADEN loads the parallel data into
the next parallel register on the second rising edge of the low-frequency
clock. You can also load data to the parallel register through the
TXLOADEN signal when using the data-realignment circuit.
