With 32 inputs and 32 outputs, a variety of rate binations is supported, under either Mux/Demux mode or Split mode, to allow for switching between streams of different data rates. Output enable indications are provided through optional pins (one pin per output stream, only 16 output streams can be used in this mode) to facilitate external data bus control. For applications requiring 32 streams and 32 per-stream Output Enable indicators, there is also an All Output Enable Feature.
