Clocks Distribution
The BlueField BF1600 Controller Card implements a “separate clocking scheme”. The Controller Card has a dedicated 100MHz oscillator clock source for
feeding its PCIe reference clock. This clock is not driven out of the card and it is expected that the downstream PCIe entities will have their own clock
source.
