Signal Integrity Products

Renesas' signal integrity products provide a 300% reach extension over passive copper solutions, and consume 80% less power than competing optical solutions. Renesas lane extender chips with analog equalizers are the perfect solution for DisplayPort™ USB-C long active cables.

About Renesas Signal Integrity ICs

As data rate and port densities continue to increase, system designers must choose between two extremes to meet their connectivity requirements. Fiber optical interconnects allow extended reaches, but the system solutions are very expensive and power-hungry. Copper cables offer a low-power solution, but the thickness, weight and attenuation limit port counts. At line rates greater than 10Gbps, passive copper cabling cannot support links over more than a few meters. Renesas' signal integrity products with Q-Active technology provide a 300% reach extension over passive copper solutions, and consume 80% less power than competing optical solutions.

With the increasing demand for higher quality video, Ultra-HD (UHD 4K) is becoming more popular and the emerging 8K video is right behind it. Video interface technology is changing to adopt the speed required for higher resolutions, color depth and refresh rates. The transition from analog video to digital video using a high-speed serial interface (e.g., HDMI, DisplayPort, LVDS, and MHL) accommodates this large data transfer. USB 3.1 Type-C combines audio, video, and bidirectional data transfer and power delivery, and is becoming a widely adopted interconnect between mobile devices, personal computers, cameras, monitors, and more. Renesas' redriver ICs with analog equalizers are the perfect solution for VESA DisplayPort v1.3 (8.1Gbps) USB-C long active cables.
