Property
Low Latency 40-100GbE IP Core
40-100GbE IP Core v14.0
Reset
Single asynchronous reset signal
resets the entire IP core. Additional
reset signals reset the individual
Avalon-MM interfaces: the control
and status interface in all IP core
variations, and the Arria 10
transceiver reconfiguration interface
in IP core variations that target an
Arria 10 device.
Five asynchronous reset signals
reset individual components of
the IP core. User must enforce
recommended reset sequence.
Clocks
Input clocks for Avalon-MM
interfaces and PLL reference clock.
PLL reference clock drives internal
IP core clocks, and
clk_rxmac
and
clk_txmac
are output clocks.
Configurable option to provide TX
MAC input clock from an external
PLL or to include the PLL in the IP
core. Clock signal from the external
MAC PLL is a new input clock
signal.
Input clocks for Avalon-MM
interfaces, PLL reference clock,
and RX and TX MAC (
clk_
rxmac
and
clk_txmac
).
Stratix V transceiver dynamic

You must instantiate an external
reconfiguration controller.
