GS2964
不建议用于新设计.
Please use GS2994, GS3440 and GS3140 for new designs.
The GS2964 is a cost optimized short reach equalizer that still supports 100m at 3Gbps. GS2964是一种高速BiCMOS集成电路,用于均衡和恢复通过75ohm同轴电缆接收的信号.
该器件设计支持SMPTE 424M, SMPTE292M和smpte259m, 并优化了270Mbps的性能, 1.485Gbps and 2.97Gbps.
GS2964具有DC恢复功能,以补偿SMPTE病理测试模式的DC含量.
The Carrier Detect output pin (CD) indicates whether a valid input signal has been detected. It can be connected directly to the MUTE pin to mute the output on loss of carrier. 电压可编程阈值, 这可以通过SQ_ADJ引脚改变, forces CD high when the input signal amplitude falls below the threshold. 这使得GS2964能够区分低幅度SDI信号和设备输入端的噪声.
The equalizing and DC restore stages are disengaged when the BYPASS pin is HIGH. 旁路模式下不均衡.
The differential outputs can be DC-coupled to Gennum® 3.3V cable drivers and reclockers and to other industry-standard 3.3V CML logic.
The GS2964 is footprint and drop-in compatible with existing GS2974 designs, 不需要额外的应用程序更改.
The device is available in a 16-pin, 4mm x 4mm QFN package.
Power consumption of the GS2964 is typically 215mW.
GS2964不含铅,封装物不含卤化阻燃剂.
This component and all homogeneous subcomponents are RoHS compliant.

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

READ NOWWhether 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. 超高清串行数字接口(UHD-SDI)和高清多媒体接口(HDMI)是数字AV传输的两种标准. UHD-SDI标准化了同轴或光纤电缆上未压缩和未加密的数字AV信号的传输. HDMI is a digital interface for transmitting high-definition, 高速数字多轨音频和未压缩视频信号从hdmi兼容的来源AV显示器. 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, 蓝光/ DVD播放器, televisions, projectors, etc. UHD-SDI是高端应用的首选,如专业的室内/室外视频制作和电视广播,因为它支持远程传输,并且在电缆两端的物理锁机制的帮助下坚固的连接. 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, 如图1所示, HDMI显示器将用于SDI流的置信度监测,以避免需要使用专门校准的SDI特定显示器.
READ NOWI designed my first product using the 串行数字接口(SDI) back in 1996, 我也不知道这个基于同轴电缆的视频接口标准将在接下来的20多年里主导我的职业生涯. Back then, SDI仅限于传输每秒270兆比特的标准清晰度(SD)数字视频。, but would evolve to higher and higher data rates to carry High Definition 720p, 1080i and 1080p, and most recently 4K Ultra High Definition (UHD) video, 电缆的长度被认为是不可能的. The convenience of a low cost single conductor coaxial copper cable, 能够传输高达1米的4K视频,这意味着SDI已经成为广播等市场事实上的AV连接选择, Pro AV, 医疗和监测.
