126.96.36.199. Connecting the Reconfiguration Controller to the IP Core
The Reconfiguration Controller communicates with the 100G Interlaken IP core on two busses:
- reconfig_to_xcvr (output)
- reconfig_from_xcvr (input)
Each of these busses connects to the bus of the same name in the 100G Interlaken IP core.
You must also connect the following signals:
- mgmt_clk_clk: Reconfiguration Controller clock (input)
- mgmt_rst_reset: Reconfiguration Controller reset (input)
- reconfig_busy: Reconfiguration Controller busy indication (output)
Intel® recommends that you set the Reconfiguration Controller input clock frequency in the range of 100 MHz to 125 MHz. Refer to the Intel® Transceiver PHY IP Core User Guide for frequency range requirements specific to the device family.
The Reconfiguration Controller reset input should be asserted high during power up and remain asserted until its clock input becomes stable. Upon power up, the Reconfiguration Controller asserts reconfig_busy output high. The reconfig_busy signal remains asserted until the Reconfiguration Controller completes the configuration of all transceivers.
