GS12150
The GS12150 is a low-power, multi-rate reclocker that features both an integrated trace equalizer and trace driver, supporting rates up to 12G UHD-SDI, inclusive of 10GbE. It is designed to receive 100Ω differential input signals, automatically recover the embedded clock from the digital video signal and re-time the incoming data. Each of the 100Ω trace inputs supports up to 17dB of insertion loss.
集成的眼图监控器可提供对后均衡输入信号的无干扰任务模式分析。 256x128 分辨率扫描矩阵可提供准确的信号分析，加速原型生成，实现场分析。 内置宏可实现定制截面分析以及快速横向和纵向眼张开度测量。
扫描和可配置空间及时间阈值之间高相位一致时，可在场中部署算法，用于分析长期信号质量变化（浴盘图），从而缩短系统安装设施间歇误差的故障排除时间。两个独立控制的跟踪驱动器具有可高度配置的预加重和摆幅控制，用于补偿长距离痕迹丢失和连接器丢失。预加重脉冲宽度和幅度可进行优化，补偿由于过孔、连接器和桩线对传输线的频率响应造成的扰动。

In this fifth and final installment of the BlueRiver applications blog series, we’ll look at how two Semtech products lines – Semtech’s BlueRiver® ASIC platform for Pro AV and SDVoE™, and broadcast Serial Digital Interface (SDI) – can enable a unique set of “SDI-over-IP” products and applications.

Whether you are watching an action replay of a baseball game on a giant screen at a stadium, a movie on your large-screen TV or streaming a video on your laptop computer, a high-quality audiovisual (AV) experience is always expected. Ultra-High-Definition Serial Digital Interface (UHD-SDI) and High-Definition Multimedia Interface (HDMI) are two standards for digital AV transmission. UHD-SDI standardizes the transmission of uncompressed and unencrypted digital AV signals over coaxial or fiber optic cables. HDMI is a digital interface for transmitting high-definition, high-speed digital multi-track audio and uncompressed video signals from HDMI-compliant sources to AV displays. Even though they both can transport ultra-high-definition AV signals from a source to a display, HDMI is preferred to connect consumer gadgets such as computers, gaming consoles, Blu-ray/DVD players, televisions, projectors, etc. UHD-SDI is preferred for high-end applications such as professional indoor/outdoor video production and television broadcasts because it supports long-range transmission and a rugged connection with the help of a physical lock mechanism at each end of the cable. UHD-SDI coaxial cable can transfer signals up to 300 feet, whereas HDMI cables struggle with excessive signal degradation even within 50 feet. These two interfaces can be used together via an HDMI-SDI or SDI-HDMI converter. For example, as shown in figure 1, an HDMI display would be used for confidence monitoring of an SDI stream to avoid the need to use specially calibrated SDI-specific displays.
