Low-power, low-jitter retimers for 4K UHD interfaces

June 22, 2016 // By Graham Prophet
Designed to resolve HDMI 2.0 and MIPI signal integrity issues in video, display and camera system designs, Texas Instruments has introduced three retimers which enable an extended signal range over long traces, connectors and cables without degradation of signal integrity.

With up to 60% lower power consumption than alternative devices and temperature range from -40C to 85C, these retimers enable robust video and camera signal quality in equipment such as desktop and laptop PCs, mobile devices, high-definition televisions (HDTVs), and automotive infotainment systems.


Features include;

- Jitter compensation: The retimers improve signal quality by removing jitter and compensating loss for signals transmitting over long traces and cables. The DP159 and TMDS181 retimers include adaptive equalization (EQ) up to 15 dB, dynamically adjusting the EQ level to fine tune system performance and enable better jitter compensation. The devices support multi-gigabit signals, such as DisplayPort and HDMI, up to 6 Gbps and operate at an extended temperature range, enabling designers to optimize performance in a wide variety of consumer, automotive and industrial equipment.

- Design flexibility: Various speed and protocol options, reprogrammable channel configuration, and scalable pin-to-pin compatibility for 1.4b and HDMI 2.0 devices enable engineers to design cost-optimized solutions.

- Increased bandwidth: The DPHY440 device is the first 4-by-1-Gbps MIPI camera serial interface (CSI) and display serial interface (DSI) retimer, providing over 10 times higher bandwidth than existing solutions enabling higher resolution camera images over long traces and cables.


DP159 and TMDS181 devices include robust features such as a pseudorandom binary sequence (PRBS) generator and real-time diagnostic EyeScan tools for in-system validation, which engineers can configure to quickly optimize their system design.
