Output Signal
PLLs 5, 6, 11, and 12 are not fast PLLs.
The input clock for PLLs used to clock receiver the rx_inclock port on the altlvds_rx megafunction must be
driven by a dedicated clock pin (CLK[3..0] and CLK[8..11]) or the corner pins that clock the corner PLLs
(FPLL[10..7]CLK).

Fast PLL Specifications
You can drive the fast PLLs by an external pin or any one of the sectional
clocks [21..0]. You can connect the clock input directly to local or global
clock lines, as shown in
inputs to the fast PLL’s input multiplexer for the receiver PLL. You can
only use the sectional clock inputs in the transmitter only mode or as a
general purpose PLL.
