Figure 5–2 shows the top-level signals of the 1G/10GbE IP Core. Some of the signals
shown in are Figure 5–2 unused and will be removed in a future release. The
descriptions of these identifies them as not functional.
Clock and Reset Interfaces
Use the Transceiver PHY Reset Controller IP Core to automatically control the
transceiver reset sequence. This reset controller also has manual overrides for the TX
and RX analog and digital circuits to allow you to reset individual channels upon
reconfiguration.
If you instantiate multiple channels within a transceiver bank they share TX PLLs. If a
reset is applied to this PLL, it will affect all channels. Altera recommends leaving the
TX PLL free-running after the start-up reset sequence is completed. After a channel is
reconfigured you can simply reset the digital portions of that specific channel instead
of going through the entire reset sequence. For more information about reset, refer to
the Transceiver Reconfiguration Controller IP Core.
