TI introduces the industry’s lowest-power, low-jitter retimers for 4K UHD video and camera interface

by donpedro

HDMI-2-0-Press-PhotoTexas Instruments (TI) introduced three high-performance retimers which enable an extended signal range over long traces, connectors and cables without degradation of signal integrity. These devices expand TI’s high-performance retimer portfolio, and support flexible, cost-optimized system design, enabling designers to speed their products to market while maintaining optimal performance. With up to 60 percent lower power consumption than competitive devices and the widest temperature range from -40C to 85C, the new 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.

Key features and benefits of the new low-power retimers

  • Leading jitter compensation: The new 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 15dB, 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.
  • Industry-leading system 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 with the lowest power consumption available today, up to 60 percent lower than competitive devices.
  • Increased bandwidth: The DPHY440 device is the industry’s 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.
  • Optimize system performance: The 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.
