The section
Bitslip Submodule
The Bitslip submodule allows designers to reorder the sequence of the parallel data
stream going into the FPGA logic. This can be used for training source-synchronous
interfaces that include a training pattern.
Dedicated Support for Strobe-based Memory Interfaces
ISERDES contains dedicated circuitry (including the OCLK input pin) to handle the
strobe-to-FPGA clock domain crossover entirely within the ISERDES block. This
allows for higher performance and a simplified implementation.
Dedicated support for Networking interfaces.
