Notes to
(1) While there is pin compatibility, there is no hard IP block placement compatibility.
(2) General purpose I/O pins cannot drive the PLL clock input pins.
(3) Provided input clock jitter is within input jitter tolerance specifications.
(4) The dedicated path between adjacent PLLs is not available on L1, L4, R1, and R4 PLLs.
(5) The smallest phase shift is determined by the voltage-controlled oscillator (VCO) period divided by eight. For degree increments, the Stratix IV
device can shift all output frequencies in increments of at least 45
divide parameters.
