OSERDES Latencies
OSERDES Timing Model and Parameters
The input to output latencies of OSERDES blocks depend on the DATA_RATE and
DATA_WIDTH attributes. Latency is defined as a period of time between the following
two events: (a) when the rising edge of CLKDIV clocks the data at inputs D1–D6 into the
OSERDES, and (b) when the first bit of the serial stream appears at OQ.
summarizes the various OSERDES latency values.
