Stratix IV Device Handbook Volume 1
Periphery Clock Networks
PCLK networks shown in
individual clock networks driven from the periphery of the Stratix IV device. Clock
outputs from the dynamic phase aligner (DPA) block, programmable logic device
(PLD)-transceiver interface clocks, horizontal I/O pins, and internal logic can drive
the PCLK networks.
PCLKs have higher skew when compared with GCLK and RCLK networks. You can
use PCLKs for general purpose routing to drive signals into and out of the Stratix IV
device.
Legal clock sources for PCLK networks are clock outputs from the DPA block,
PLD-transceiver interface clocks, horizontal I/O pins, and internal logic.
