ISERDES Latencies
ISERDES Timing Model and Parameters
When the ISERDES interface type is MEMORY, the latency through the OCLK stage is one
CLKDIV cycle. However, the total latency through the ISERDES depends on the phase
relationship between the CLK and the OCLK clock inputs. When the ISERDES interface
type is NETWORKING, the latency is two CLKDIV cycles. See
Figure 8-13, page 369
cycle of latency in networking mode (compared to memory mode) is due to the Bitslip
submodule.
