Arria II GZ devices have a dedicated PLL cascade network on the left and right side of
the device that connects to the input reference clock selection multiplexer of the CMU
PLLs, and receiver CDRs on the left and right side of the device.
The dedicated PLL cascade networks are segmented by bidirectional tri-state buffers
located along the clock line. Segmentation of the dedicated PLL cascade network
allows two or more left and right PLLs to drive the cascade clock line simultaneously.
Because the number of left and right PLLs and transceiver blocks vary from device to
device, the capability of cascading a left and right PLL to the CMU PLLs, and receiver
CDRs also varies from device to device.
The following sections describe the Arria II GZ FPGA fabric-transceiver PLL’s
cascading for the various device packages.
Arria II GZ devices in 780-pin packages do not support FPGA fabric PLLs-transceiver
PLL’s cascading.
