DESCRIPTION
The SN75DP122A 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 SN75DP122A data rates of up to 2.7 Gbps through each link for a total throughput of up to 10.8 Gbp.
