The SN75DP122 is a one Dual-Mode DisplayPort input to one Dual-Mode DisplayPort output or one TMDS output. The TMDS output has a built in level translator compliant with Digital Video Interface (DVI) 1.0 and High Definition Multimedia Interface (HDMI) 1.3b. The DisplayPort output follows 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 SN75DP122 data rates of up to 2.7 Gbps through each link for a total throughput of up to 10.8 Gbps can be realized.
In addition to the switching of the DisplayPort high speed signal lines, the SN75DP122 also supports the switching of the bidirectional auxiliary (AUX), Hot Plug Detect (HPD), and Cable Adapter Detect (CAD) channels. The Auxiliary differential pair supports Dual-Mode DisplayPort operation through the DisplayPort port. Through the TMDS port the auxiliary port is configured as an I2C port with an integrated I2C repeater.
The SN75DP122 is characterized for operation over ambient air temperature of 0°C to 85°C.
