SN75DP128A,PDF(Display Port 1:

The SN75DP128A 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 SN75DP128A data rates of up to 2.7Gbps through each link for a total throughput of up to 10.8Gbps can be realized. The SN75DP128A supports Display Port Spec 1.1a.

In addition to the switching of the DisplayPort high speed signal lines, the SN75DP128A also supports the switching of the bi-directional auxiliary (AUX), Hot Plug Detect (HPD), and Cable Adapter Detect (CAD) channels. The Auxiliary differential pair supports Dual-Mode DisplayPort operation with the ability to be configured as a bi-directional differential bus while in DisplayPort mode or an I2C™ bus while in TMDS mode.
