Data delay through the switching paths
For all data rates, the received serial data is converted to parallel format and stored sequentially in the data memory.
Each data memory location corresponds to an input stream and channel number. To provide constant delay and
maintain frame integrity, the MT90869 utilizes four pages of data memory. Consecutive frames are written in turn to
each page of memory. Reading is controlled to allow a channel data written in frame N to be read during frame N+3.
A constant delay of three frames is applied to all switching paths irrespective of data-rate or channel number. See
Figure 16, Constant Switch Delay: Examples of different stream rates and routing
.
