pld_clk
coreclkout_hip
can drive the Application Layer clock along with the
pld_clk
input to the IP core. The
pld_clk
can optionally be sourced by a different clock than
coreclkout_hip
. The
pld_clk
minimum
frequency cannot be lower than the
coreclkout_hip
frequency. Based on specific Application Layer
constraints, a PLL can be used to derive the desired frequency.
Clock Summary
Table 8-2: Clock Summary
Name Frequency Clock Domain
coreclkout_hip 62.5, 125 or 250 MHz Avalon-ST interface between the Transaction and
Application Layers.
pld_clk 62.5, 125, or 250 MHz Application and Transaction Layers.
refclk
100 MHz SERDES (transceiver). Dedicated free running input
clock to the SERDES block.
hip_reconfig_clk 50–125 MHz Avalon-MM interface for Hard IP dynamic reconfi‐
guration interface which you can use to change the
value of read-only configuration registers at
run-time. This interface is optional. It is not
required for Arria 10 devices.
