42 / 104 page ![]() 2–36 Altera Corporation Preliminary January 2007 Cyclone Device Handbook, Volume 1 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 VCC and ground voltage supplies. Therefore, to minimize jitter, do not place switching I/O pins next to these output pins.
