You can use every LVDS channel in soft-CDR mode and can drive the FPGA fabric
using the periphery clock network in the Stratix IV device family. The rx_dpa_locked
signal is not valid in soft-CDR mode because the DPA continuously changes its phase
to track PPM differences between the upstream transmitter and the local receiver
input reference clocks. The parallel clock rx_outclock, generated by the left and right
PLL, is also forwarded to the FPGA fabric.
The ALTLVDS MegaWizard Plug-In Manager software provides an option for
implementing the LVDS interface with the Use External PLL option. With this option
enabled you can control the PLL settings, such as dynamically reconfiguring the PLL
to support different data rates, dynamic phase shift, and other settings. You also must
instantiate an ALTPLL megafunction to generate the various clock and load enable
signals.
When you enable the Use External PLL option with the ALTLVDS transmitter and
receiver, the following signals are required from the ALTPLL megafunction:

As an example,
parallel clock output generated on ports c0, c1, and c2, respectively, along with the
locked signal of the ALTPLL instance. You can choose any of the PLL output clock
ports to generate the interface clocks.
With soft SERDES, a different clocking requirement is needed. For more information,
refer to the
Guide.
The high-speed clock generated from the PLL is intended to clock the LVDS SERDES
circuitry only. Do not use the high-speed clock to drive other logic because the
allowed frequency to drive the core logic is restricted by the PLL F
