Achieving Deterministic Latency
This section provides an overview of the calculation that help you achieve deterministic delay in the
Deterministic Latency PHY IP core.
This figure illustrates the TX and RX channels when configured as a wireless basestation communicating
to a remote radio head (RRH) using a CPRI or OBSAI interface. The figure also provides an overview of
the calculations that guarantee deterministic delay. As this figure illustrates, you can use a general-
purpose PLL to generate the clock that drives the TX CMU PLL or an external reference clock input pin.
