This is an optional port.
Only one rx_pll_enable pin is necessary to enable all the PLLs in the device.
This is a non-differential pin.

Port Name
When you span two I/O banks using cross-bank support, you can route
only two load enable signals total between the plls. When you enable
rx_data_align, you use both rxloadena and txloadena of a PLL.
That leaves no loadena for the second PLL.
The only way you can use the rx_data_align is if one of the following
is true:

LVDS Receiver Block
You only need to enter the input clock frequency, deserialization factor,
and the input data rate to implement an LVDS receiver block. The
Quartus II software then automatically sets the clock boost (W) factor for
the receiver. In addition, you can also indicate the clock and data
alignment for the receiver or add the pll_enable, rx_data_align,
and rx_locked output ports.
available ports in the LVDS receiver block.
The RX PLL is only clocking RX channels (no resources for TX)
If all channels can fit in one I/O bank
