altlvds with shared pll

Hello,

I am using a Cyclone with one PLL available and I want to have a LVDS Transmitter and Receiver which are sharing this PLL. I tried to follow the instructions of the Design Guidelines for Implementing LVDS Interfaces in Cyclone Series Devices (App Note 479) but the Quartus Fitter quits with the following error message:

Error: Project requires 2 fast or enhanced PLLs, but the target device can contain only 1 fast or enhanced PLLs

Could someone help me, please! I have no idea what I can do about this. I also tried to connect the outclk from the receiver to the inclk of the transmitter but then I get this error message:

Error: inclk0 port of PLL ... must be driven by a non-inverted input pin or, in a fast PLL, the output of a PLL.

Thanks in advance

Stephan
