The EP1C3 device in the 100-pin TQFP package does not support external outputs or LVDS inputs. The EP1C6
device in the 144-pin TQFP package does not support external output from PLL2.
LVDS input is supported via the secondary function of the dedicated clock pins. For PLL 1, the CLK0 pin’s secondary
function is LVDSCLK1p and the CLK1 pin’s secondary function is LVDSCLK1n. For PLL 2, the CLK2 pin’s secondary
function is LVDSCLK2p and the CLK3 pin’s secondary function is LVDSCLK2n.

÷n
The m counter ranges from 2 to 32. The n counter and the post-scale counters
range from 1 to 32.
The smallest phase shift is determined by the voltage-controlled oscillator (VCO)
period divided by 8.
For degree increments, Cyclone devices can shift all output frequencies in
increments of 45°. Smaller degree increments are possible depending on the
frequency and divide parameters.
The EP1C3 device in the 100-pin TQFP package does not support external clock
output. The EP1C6 device in the 144-pin TQFP package does not support external
clock output from PLL2.
