Preliminary
External Clock Inputs
Each PLL supports single-ended or differential inputs for source-
synchronous receivers or for general-purpose use. The dedicated clock
pins (CLK[3..0]) feed the PLL inputs. These dual-purpose pins can also
act as LVDS input pins. See
Table 2–8
pins.

page
External Clock Outputs
Each PLL supports one differential or one single-ended output for
source-synchronous transmitters or for general-purpose external clocks.
If the PLL does not use these PLL_OUT pins, the pins are available for use
as general-purpose I/O pins. The PLL_OUT pins support all I/O
standards shown in
The external clock outputs do not have their own V
supplies. Therefore, to minimize jitter, do not place switching I/O pins
next to these output pins. The EP1C3 device in the 100-pin TQFP package
