SLLS940 – NOVEMBER 2008 DisplayPort 1:2 Switch FEATURES 1 One Input Port to One of Two Output Ports Supports Data Rates up to 2.7Gbps Supports Dual-Mode DisplayPort Output Waveform Mimics Input Waveform Characteristics Enhanced ESD: – 12kV on all Main Link Pins – 10kV on all Auxiliary Pins Enhanced Commercial Temperature Range: 0°C to 85°C 56 Pin 8 × 8 QFN Package APPLICATIONS Personal Computer Market – Desktop PC – Notebook PC – Docking Station – Standalone Video Card DESCRIPTION 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-directiona...
