GS2988
The GS2988 is a SMPTE-compatible, dual-output cable driver which supports data rates from 270Mb/s to 2.97Gb/s. The GS2988 is a high-speed BiCMOS integrated circuit designed to drive one or two 75Ω coaxial cables.
GS2988 可以驱动高达 2.97Gbps 的数据速率，并提供两种可选的转换速率，以符合 SMPTE 424M、SMPTE 292M 和 SMPTE 259M。GS2988 接受行业标准的差分输入电平，包括 LVPECL 和 CML。
输入迹线均衡可补偿高达 10 英寸的 FR4 迹线损耗。可以使用 EQ_EN 引脚禁用此功能。DISABLE 引脚关断输出驱动器，使串行数据输出处于高阻抗状态。GS2988 使用外部偏置电阻器，具有可调节的输出摆幅。单端输出摆幅可在 500mVpp 至 1800mVpp 范围内调节。输出信号感测功能（OSP 引脚）指示 GS2988 的输出端是否存在有效信号。
GS2988 可由 3.3V 或 2.5V 电源供电。使用 2.5V 电源时，功耗通常为 125mW。
GS2988 为无铅设备，包封复合物中不含有卤系阻燃剂。此部件和所有同类子部件均符合 RoHS 要求。
GS2988 与 Semtech 的 GS6080 6G UHD-SDI 电缆驱动器插槽兼容。

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.
