I n order to keep the compatibility of HDMI TH to most monitors, AT-3GSDI500 features EDID learning ability. The operation is shown in the EDID LEARNING section.1. Power off AT-3GSDI500 and set the pin 4 of DIP switch of AT-3GSDI500 to OFF [↓].2. Connect the HDTV to the HDMI TH port on the AT-3GSDI500, and then power on AT-3GSDI500.3. The Lock LED on the AT-3GSDI500 will dim and light again, which indicates the EDID learning process is done.4. Connect AT-3GSDI500 to the HDMI TH source through a HDMI TH cable and enjoy the experience.1. I n HDMI TH bypass mode, users must be aware of that the jitters coming from HDMI TH sources, such as DVD players, may be much higher than typical requirement according to SMPTE request on HD-SDI signals. This will result in SDI output with high jitters or even no SDI outputs!2. D ue to the high frequency bandwidth and low jitter requirement of 3G-SDI signals, for single SDI output case, it is strongly recommended to use one 75 ohm terminator for the unused SDI output to keep the best performance.11 |toll free: 1-877-536-3976For International: 1-408-962-0515● D ata Type 1(SMPTE-291M)9.2.

MIC4834 Block Diagram Functional DescriptionOverviewThe MIC4834 is a high-voltage dual output EL driver with a peak-to-peak AC output voltage of 220V capable of driving two 3 in2 EL panels. The MIC4834 drives EL panels by converting a low DC input voltage to a high DC high output voltage using the boost regulator circuit and then alternating the high DC voltage across the EL panel using an H-Bridge. Input supply current for the MIC4834 is typically 152µA. The high voltage EL driver has two internal oscillators to control the boost switching frequency and the H-bridge driver frequency. The internal boost oscillator frequency can be individually programmed through an external resistor to maximize efficiency and brightness of the EL panel. The H-bridge frequency is internally fixed at 225Hz to reduce external component count.R egulationReferring to Figure 1, power is initially applied to V DD. When the internal feedback voltage is less than the reference voltage, the internal comparator enables switching in the boost circuit. When the boost regulator is switching, current flows through the inductor into the switch. The switching MOSFET will typically turn on for 90% of the switching period. During the on-time, energyis stored in the inductor. When the switching MOSFET turns off, current flowing into the inductor forces the voltage across the inductor to reverse polarity. The voltage across the inductor rises until the external diode conducts and clamps the voltage at V OUT + V D1. The energy in the inductor is then discharged into the C OUT capacitor. The internal comparator continues to turn the switching MOSFET on and off until the internal feedback voltage is above the reference voltage. Once the internal feedback voltage is above the reference voltage, the internal comparator disables switching. The control circuit will continue to turn the MOSFET’s on and off to maintain a constant DC voltage at the CS pin.When the MIC4834 EL Driver is enabled, ELA and ELB will switch in opposite states with COM to achieve a 220V peak-to-peak AC output signal needed to drive the two EL panels.Switching FrequencyThe switching frequency of the converter is controlled by an external resistor (R SW ) between RSW and VDD. The switching frequency increases as the resistor value decreases. In general, the lower the switching frequency, the greater the input current is drawn to deliver more power to the output. Lowering the switching frequency can be used to drive larger panels. However, the switching frequency should not be so low as to allow the voltage at the switch node or the CS pin to exceed the absolute maximum voltage of those pins. For resistor value selections, see the “Typical Characteristics: Switching Frequency vs. SW Resistor” graph on Page 4 or use the equation below. The switching frequency range is 35kHz to 350kHz, with an accuracy of ±20%.()Ω=M R 46(kHz)f SW SWEL FrequencyThe MIC4834 EL panel frequency is internally fixed at 225Hz.Enable FunctionThere are a few different ways to enable and disable the MIC4834. The boost regulator may be disabled by pulling the R SW resistor to ground. This turns off both the EL panels by cutting power to the device completely. The R SW resistor must be pulled to VDD to enable the boost oscillator. If it is not equal to VDD, then the frequency set by R SW will be different the programmed value.For individual panel control, the ENA and ENB pins can be used to enable ELA and ELB, respectively. Pulling ENA or ENB high (over 1.2V) or low (below 0.4V) willturn ELA and ELB panels on or off.Figure 2. EL Panel Waveform – 2 × 1 in2Figure 3. EL Panel Waveform – 2 × 2 in 2Figure 4. EL Panel Waveform – 2 × 3 in 2Application InformationThe MIC4834 is designed to use an inductance with a value between 100µH to 330µH. Choosing the right inductor is always a balance of size, inductance, efficiency, current rating and cost. A TDK (VLS4012T-221M) 220µH inductor is recommended based on size, efficiency and current rating.Generally, the lower the inductance, the more current the inductor can handle. Lowering the inductance allows the boost regulator to draw more input current to deliver more energy every switching cycle. As a result, a lower inductance may be used to drive larger panels or brighten similar sized panels. However, caution is required as using a low inductance with a low switching frequency may cause the voltage at the switch node and the CS pin to exceed the absolute maximum rating. If the application uses a low input voltage (2.3V to 3V), then a lower value inductor, such as 100µH, may be used in order to drive the EL panel at maximum brightness.DiodeThe diode must have a high reverse voltage (150V), since the output voltage at the CS pin can reach up to 130V. A fast switching diode with lower forward voltage and higher reverse voltage (150V), such as BAV20WS/BAS20W, can be used to enhance efficiency. Output CapacitorLow ESR capacitors should be used at the regulated boost output (CS pin), to minimize the switching output ripple voltage. The larger the output capacitance, the lower the output ripple at the CS pin. The reduced output ripple, at the CS pin, along with a low ESR capacitor improves the efficiency of the MIC4834 circuit. Selection of the capacitor value depends upon the peak inductor current, inductor size, and the load. The MIC4834 is designed for use with an output capacitance as low as 2.2nF. For minimum audible noise, the use of a C0G/NPO dielectric output capacitor is recommended. TDK and AVX offer C0G/NPO dielectric capacitors in capacitance up to 2.7nF at 200V to 250V voltage rating in 0805 size.EL Panel Terminals (ELA, ELB, COM)The two EL panels are connected from ELA to COM and ELB to COM. The ELA and ELB terminals are in phase with each other, while the COM is out of phase with both ELA and ELB. Since ELA and COM are out of phase, the high voltage generated by the boost regulator is alternated across ELA and COM by the H-Bridge. The frequency of each cycle is internally fixed at 225Hz. The alternating 220V peak-to-peak causes the EL panel to emit light. Similarly, the ELB and COM are also out of phase and allows a second EL panel to be driven at the same time. Both EL panels may operate independently from each other and do not have to be the same size. For component selection, Table 2 lists recommended values for various panel sizes up to a total of 6 in2 (For example, two 3 in2 panels). Driving overly large panels will result in a dimmer display, but will not cause damage to the device.Application CircuitFigure 6.

数字高清解决方案之HD-SDI
HD-SDI大家并不陌生，在人们追寻看得到到看得清的阶段产生的技术，它突破了标清系统或早期的模拟系统的瓶颈，为前端HD-SDI技术优势随着社会经济的发展，对安防监控的需求也日渐增长，而传统视频监控
系统存在清晰度低、视线范围窄小、目标观察不清等弊端，市场需要新的技术
来改变这一现状，此时HD-SDI也应运而生。
所谓的HD-SDI高清摄像机，是基于SMPTE(电影与电视工程师协会)串
行链路标准，通过75欧姆同轴电缆来传输未压缩的数字视频的一种高清实时摄
像机。
SDI接口也可简单分为以下三种：标准清晰度SD-
SDI(270Mbps，SMPTE259M),高清标准HD-SDI(1.485Gbps,SMPTE292M)、3G- SDI(2.97Gbps,SMPTE424M)。

国半推出业界最低抖动的3Gbps SDI均衡器LMH0384
美国国家半导体公司(National Semiconductor Corporation,NS)最新推出的PowerWise 3Gbps(3G) 串行数字接口(SDI)电缆均衡器可以简化多种不同产品的系统设计，可广泛应于广播设备视频路由器、视频交换器、视频分配放大器、编辑及转换设备等各类系统设计。
这款功耗极底的均衡器LMH0384不论电缆长短，信号的输出对准抖动都低于其他同类产品，更符合工程师对硬件产品设计的要求。
一般来说，抖动规定越严格，系统噪声越少，换言之，信号错误越少，影像越清晰亮丽。
LMH0384芯片可支持长达110米的Belden 1694A 双扭线电缆，而且以2.97Gbps 的速度传送信号时，是目前唯一一款输出抖动保证低于0.3UI的均衡器。
如传输率高达3G，这款均衡器可在长达140米的电缆上执行均衡功能；如以高清晰度(HD)的速率传送信号，传送距离可高达200米；如采用标准清晰度(SD)的速率，传送距离则可高达400米。
这款均衡器芯片在接收输入信号时，可以根据电缆长度灵活调整均衡电平，而且只需一条双扭线电缆便可以每秒60帧的速度传送1080p的高清晰度广播视频，同时保证极低的抖动。
美国国家半导体的LMH0384芯片可支持两种操作模式，即引脚模式及寄存器模式。
采用引脚模式时，这款均衡器可与美国国家半导体SDI均衡器系列的其他型号产品全面兼容。
若采用寄存器模式，工程师则可通过串行外围设备接口(SPI)总线利用其中的多种先进功能，优点是无需修改电路板设计便可灵活更改及诊断产品的参数。
这些先进功能包括自动停机(自动休眠)、电缆长度指示、可编程偏移及幅度的LVDS驱动以及可启动外置分配器的可编程输入启动振幅等功能。
另外，LMH0384均衡器的输出共模电压还可让工程师灵活调整(1.05V至1.85V)，令这款芯片可与大部分FPGA芯片及信号调整电路直接耦合而无需加设电平转换缓冲器。
这款均衡器配备主动检测功能，可减少系统的功耗，甚至可将散热装置需求减至最少。
例如当线路断开或信号遗失时，LMH0384芯片会自动进入有助节能的休眠模式，将功耗降低85%。
若采用正常操作模式而电缆长度不超过140米，这款均衡器可自动切换均衡级，以便将功耗减少20%。
如采用一个3.3V的电源供应操作，这款均衡器的功耗只有230mW(典型值)。
美国国家半导体为广播设备提供一系列视频产品，LMH0384芯片是该系列产品的最新型号，其特点是可以支持电影及电视工程师协会(SMPTE)的SMPTE 424M、SMPTE 292M及SMPTE 259M 标准，适用于未压缩串行数字视频信号路径选择及视频处理系统。
此外，LMH0384芯片也可全面支持270Mbps的数字视频广播异步串行接口(DVB-ASI) 标准，让前端设备可以添加压缩视频分配功能。
价格及供货情况
LMH0384芯片采用16-LLP封装，采购以100颗为单位，单颗价为21 美元，已有样品供应，批量供货则定于2009年5月开始。
