The SN75DP128 is a one Dual-Mode DisplayPort input to one of two Dual-Mode DisplayPort outputs. The
outputs will follow the input signal in a manner that provides the highest level of signal integrity while supporting
the EMI benefits of spread spectrum clocking. Through the SN75DP128 data rates of up to 2.7Gbps through
each link for a total throughput of up to 10.8Gbps can be realized.
In addition to the switching of the DisplayPort high speed signal lines, the SN75DP128 also supports the
switching of the bi-directional auxiliary (AUX), Hot Plug Detect (HPD), and Cable Adapter Detect (CAD) …
