does not have dedicated clock output pins. The EP1C6 device in the
144-pin TQFP package only supports dedicated clock outputs from
PLL 1.
Clock Feedback
Cyclone PLLs have three modes for multiplication and/or phase shifting:
■

■
Phase Shifting
Cyclone PLLs have an advanced clock shift capability that enables
programmable phase shifts. You can enter a phase shift (in degrees or
time units) for each PLL clock output port or for all outputs together in
one shift. You can perform phase shifting in time units with a resolution
range of 125 to 250 ps. The finest resolution equals one eighth of the VCO
period. The VCO period is a function of the frequency input and the
multiplication and division factors. Each clock output counter can choose
a different phase of the VCO period from up to eight taps. You can use this
clock output counter along with an initial setting on the post-scale
counter to achieve a phase-shift range for the entire period of the output
clock. The phase tap feedback to the m counter can shift all outputs to a
single phase. The Quartus II software automatically sets the phase taps
and counter settings according to the phase shift entered.
Lock Detect Signal
The lock output indicates that there is a stable clock output signal in
phase with the reference clock. Without any additional circuitry, the lock
signal may toggle as the PLL begins tracking the reference clock.
Therefore, you may need to gate the lock signal for use as a
system-control signal. For correct operation of the lock circuit below

Global Clock Network and Phase-Locked Loops
Zero delay buffer mode⎯ The external clock output pin is phase-
aligned with the clock input pin for zero delay.
Normal mode⎯ If the design uses an internal PLL clock output, the
normal mode compensates for the internal clock delay from the input
clock pin to the IOE registers. The external clock output pin is phase
shifted with respect to the clock input pin if connected in this mode.
You defines which internal clock output from the PLL should be
phase-aligned to compensate for internal clock delay.
No compensation mode⎯ In this mode, the PLL will not compensate
for any clock networks.
