PLLs in Arria II Devices
Figure 5–16. PLL Block Diagram for Arria II Devices
Notes to
(1) The number of post-scale counters is seven for left and right PLLs and ten for top and bottom PLLs.
(2) This is the VCO post-scale counter K.
(3) The FBOUT port is fed by the M counter in Arria II PLLs. The FBOUT port is only available in Arria II GZ devices.

Arria II PLL.
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.
PLL Clock I/O Pins
For Arria II GX devices, each PLL supports one of the following clock I/O pin
configurations:
■
■
One single-ended I/O or one differential I/O pair.
Three single-ended I/O or three differential I/O pairs (this is only supported in
PLL_1 and PLL_3 of EP2AGX95, EP2AGX125, EP2AGX190, and EP2AGX260
devices). You can only access one differential I/O pair or one single-ended pin at a
time.
