Chapter 2: Transceiver Clocking in Arria II Devices
FPGA Fabric PLL-Transceiver PLL Cascading
December 2010 Altera Corporation
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 left PLLs to drive the cascade clock line simultaneously to provide the
input reference clock to the CMU PLLs and receiver CDRs in different transceiver
blocks.
The following sections describe the dedicated PLL cascade networks available in the
Arria II GX device family.
The FPGA fabric PLLs-transceiver PLLs cascading option is available in the following
Arria II GX devices with four channels:
