Notes to
(1) All disabled blocks and signals are grayed out.
(2) In DDR mode, tx_inclock clocks the IOE register. In SDR mode, data is directly passed through the IOE.
(3) In SDR and DDR modes, the data width to the IOE is 1 and 2, respectively.

Differential applications often require specific clock-to-data alignments or a specific
data rate to clock rate factors. You can configure any Arria II GX LVDS transmitter to
generate a source-synchronous transmitter clock output. This flexibility allows the
placement of the output clock near the data outputs to simplify board layout and
reduce clock-to-data skew. The output clock can also be divided by a factor of 1, 2, 4, 6,
8, or 10, depending on the serialization factor. The phase of the clock in relation to the
data can be set at 0° or 180° (edge or center aligned). The center and corner PLLs
provide additional support for other phase shifts in 45° increments.
