TI SN75DP159RGZT

The SNx5DP159 device is a dual-mode DisplayPort to Transition Minimized Differential Signaling (TMDS) retimer that supports Digital Visual Interface (DVI) 1.0 and High-Definition Multimedia Interface (HDMI) 1.4b and 2.0 output signals. The SNx5DP159 device supports Class 1 and Class 2 applications of the dual-mode standard version 1.1 through the DDC link or the AUX channel. Each data channel of the SNx5DP159 device supports a data rate of up to 6Gbps, enabling support for Ultra-High Definition (4K×2K/60Hz) 8-bit color high-resolution video and High-Definition Television (1920 × 1080/60Hz) with 1080p 16-bit color depth. The SNx5DP159 device can be automatically configured as a pass-through driver when the data rate is below 1Gbps and as a retimer when the data rate exceeds this value. This feature can be disabled through I²C[4] programming. To ensure signal integrity, the SNx5DP159 device implements multiple features. The SNx5DP159 receiver supports adaptive and fixed equalization to eliminate Inter-Symbol Interference (ISI) jitter or losses caused by bandwidth limitations in board traces or cables. When used as a retimer, the built-in Clock and Data Recovery (CDR) function can remove random jitter from the high-frequency input and the video source. The transmitter provides various functions that not only help meet compliance requirements but also reduce system design issues. For example, the de-emphasis function can compensate for attenuation when driving long cables or high-loss board traces. The SNx5DP159 device also includes a TMDS output amplitude adjustment function implemented using an external resistor on the Vsadj pin, as well as a source selection function and an output slew rate control function. The operation and configuration of the device can be set through pin settings or I²C[4] programming. The SNx5DP159 device uses multiple methods for power management and to reduce active power.
