You can drive the GCLK or RCLK clock input with an output from another PLL, a
pin-driven GCLK or RCLK, or through a clock control block, provided the clock
control block is fed by an output from another PLL or a pin driven dedicated GCLK or
RCLK. An internally-generated global signal or general purpose I/O (GPIO) pin
cannot drive the PLL.
Input clock switchover
Notes to
(1) PLL_5 and PLL_6 do not have dedicated clock outputs.
(2) The same PLL clock output drives three single-ended or three differential I/O pairs. This is only supported in
(3) This is applicable only if the input clock jitter is within the input jitter tolerance specifications.
(4) The smallest phase shift is determined by the voltage-controlled oscillator (VCO) period divided by eight. For

degree increments, the Arria II GX device can shift all output frequencies in increments of at least 45°. Smaller
degree increments are possible depending on the frequency and C counter value.
