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
Figure 2–25
.
Table 2–8
shows the I/O standards supported by PLL input and output
pins.
For more information on LVDS I/O support, see
“LVDS I/O Pins” on
page 2–54
.
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
Table 2–8
.
The external clock outputs do not have their own V
CC
and ground voltage
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
