Stratix IV Device Handbook Volume 1
The load enable (LVDS_LOAD_EN) signal and the diffioclk signal (the clock running at
serial data rate) generated from PLL_Lx (left PLL) or PLL_Rx (right PLL) clocks the load
and shift registers. You can statically set the serialization factor to ×3, ×4, ×6, ×7, ×8, or
×10 using the Quartus II software. The load enable signal is derived from the
serialization factor setting.

Notes to
(1) In SDR and DDR modes, the data width is 1 and 2 bits, respectively.
(2) The tx_in port has a maximum data width of 10 bits.
You can configure any Stratix IV transmitter data channel 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. Different applications often require specific clock-to-data
alignments or specific data-rate-to-clock-rate factors. The transmitter can output a
clock signal at the same rate as the data with a maximum frequency of 800 MHz. The
output clock can also be divided by a factor of 1, 2, 4, 6, 8, or 10, depending on the
serialization factor. You can set the phase of the clock in relation to the data at 0° or
180° (edge or center aligned). The left and right PLLs (PLL_Lx and PLL_Rx) provide
additional support for other phase shifts in 45° increments. These settings are made
statically in the Quartus II MegaWizard Plug-In Manager software.
