Preliminary Information
Altera Corporation
Each PLL has one pre-scale divider, n, that can range in value from 1 to 32.
Each PLL also has one multiply divider, m, that can range in value from 2
to 32. Global clock outputs have two post scale G dividers for global clock
outputs, and external clock outputs have an E divider for external clock
output, both ranging from 1 to 32. The Quartus II software automatically
chooses the appropriate scaling factors according to the input frequency,
multiplication, and division values entered.
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 11
pins.
For more information on LVDS I/O support, see
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
3.3-V LVTTL/LVCMOS
