Typical properties for CHO-SEAL 1310 and 1273 materi-al are shown on pages 33 and 32respectively.High Shielding PerformanceCHO-SEAL 1310 material provides more than 80 dB of shielding effectiv-ness from 100 MHz to 10 GHz, while CHO-SEAL 1273 material provides more than 100 dB.Low Volume ResistivityBoth materials have exceptionally low volume resistivity, which makes them well suited for grounding appli-cations in which a flexible electrical contact is needed.Low Compression GasketSpacer gaskets are typicallydesigned to function under low deflec-tion forces. Chomerics uses design tools such as Finite Element Analysis (FEA) to accurately predict compres-sion-deflection behavior of various cross section options. Refer to page16.LCP Plastic SpacerLiquid crystal polymer (LCP)spacers, including those made with Vectra A130 material, provide aCHO-SEAL ®1310 or 1273Conductive ElastomersWith EMI spacer gaskets, shielding and grounding are provided by Chomerics’CHO-SEAL 1310 and 1273 conductive elastomers, specifi-cally formulated for custom shape molded parts. They provide excellent shielding and isolation against electro-magnetic interference (EMI), or act as a low impedance ground path between PCB traces and shielding media. Physically tough, these elas-tomers minimize the risk of gasket damage, in contrast to thin-walled extrusions or unsupported molded gaskets.Silicone-based CHO-SEAL 1310and 1273 materials offer excellent resistance to compression set over a wide temperature range, resulting in years of continuous service. CHO-SEAL 1310 material is filled with silver-plated-glass particles, while 1273 utilizes silver-plated-copper filler to provide higher levels of EMI shielding effectiveness.EMI Spacer GasketsThe unique design of Chomerics’EMI spacer gaskets features a thin plastic retainer frame onto which a conductive elastomer is molded. The elastomer can be located inside or outside the retainer frame, as well as on its top and bottom surface. EMI spacer gaskets provide a newapproach to designing EMI gaskets into handheld electronics such as dig-ital cellular phones. Board-to-board spacing is custom designed to fit broad application needs. Customized cross sections and spacer shapes allow for very low closure forcerequirements and a perfect fit in any design or device.Robotic InstallationSpacer gaskets can be installed quickly by robotic application. Integral locater pins in the plastic spacer help ensure accuratepositioning in both manual and pick-and-place assembly. Benefits include faster assembly and lower labor costs.The integrated conductive elastomer/plastic spacer gasket is a low cost,easily installed system for providing EMI shielding and grounding in small electronic enclosures.Figure 1Single Piece EMI Gasket/Locator PinsCHO-SEAL 1310 or 1273 Conductive Elastomer (Inside)Plastic Spacer Around Outsideor InsideApplications for EMI Spacer GasketsThe spacer gasket concept is especially suited to digital and dual board telephone handsets or other handheld electronic devices. It provides a low impedance path between peripheral ground traces on printed circuit boards and components such as:•the conductive coating on a plastic housing•another printed circuit board •the keypad assemblyTypical applications for EMI spacer gaskets include:•Digital cellular, handyphone and personal communications services (PCS) handsets •PCMCIA cards•Global Positioning Systems (GPS)•Radio receivers•Other handheld electronics, e.g.,personal digital assistants (PDAs)•Replacements for metal EMI shield-ing “fences” on printedcircuit boards in wireless tele-communications devicesstable platform for direct, highprecision molding of conductive elas-tomers. The Vectra A130 material described in Table 1 has excellent heat deflection temperature character-istics (489°F, 254°C). For weight con-siderations, the LCP has aspecific gravity of only 1.61. This plas-tic is also 100% recyclable.Typical EMI Spacer Gasket Design ParametersThe EMI spacer gasket concept can be considered using the design parameters shown in Table 2.

This unit specializes in elastomer finite element analysis (FEA) using MARC K6 series software as a foundation for FEA capability.Benefits of FEA include:•Quickly optimizing elastomer gasket designs•Allowing accurate predictions of alternate elastomer design concepts •Eliminating extensive trial and error prototype evaluationTypical use of FEA in EMI spacer gasket designs is to evaluate the force vs. deflection requirements of alternate designs.For example, onespacer design features a continuous bead of con-ductive elastomer molded onto a plastic spacer. An alternative designemploys an “interrupted bead,” where the interrup-tions (gaps left on the plastic frame) are sized to maintain the requiredlevel of EMI shielding. Figure 4illustrates these alternative designs.Gasket DeflectionFigure 5 compares the effect of continuous and interrupted elastomer gasket designs in terms of the force required to deflect the conductive elastomer. This actual cellular handset application required a spacer gasket with interrupted bead to meet desired deflection forces.Chomerics Designand Application ServicesChomerics will custom design a spacer for your application.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
The MAX1619 is nearly identical to the popular MAX1617A, with the additional feature of an overtemperature alarm output (OVERT) that responds to the remote temperature; this is optimal for fan control.

MAX3088ESA+中文资料

The MAX3080–MAX3089 high-speed transceivers for RS-485/RS-422 communication contain one driver and one receiver. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The MAX3080/MAX3081/MAX3082 feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. The MAX3083/MAX3084/MAX3085 offer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086/MAX3087/MAX3088’s driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089’s slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a single three-state driver.

MAX266中文数据手册

MAX266中文数据手册MAX266/265中文数据手册By Hi_Cracker @whu引脚电阻可编程通用高效滤波器-----MAX266/265General Description和MAX265是高效的容滤波器，专门设计用于需要高精度滤波的应用MAX266场合。

内置了两个独立的滤波模块，可以配置成低通，高通，带通，带阻，全通滤波器。

中心频率或者截止频率的控制需要外接电阻以及6 Pin-Strapped 的输入特性来编程实现，然而，Q值仅用电阻连接实现。

各种各样类型的滤波器都可以实现（巴特沃斯，切比雪夫，椭圆滤波器等等）。

内部集成了两个运算放大器。

MAX265可以将中心/截止频率可以最高调到40Khz，然而，MAX266，通过使用一个低范围的fclk/fo比例系数，可以将fos 调到140Khz。

4MHZ系统时钟，可以通过一个晶振或是额外的源获得。

滤波器的操作电压为从±2.37v到±6.3v或者+5V的单电源供电。

Application：声纳电子设备Anti-Aliasing 滤波器数字信号处理震动音频分析远程通信测试仪器Features滤波器参数设置软件化256bit的频率控制字电阻调整Q值和fo140Khz频率调节范围±5V或者单电源﹢5V操作电压Introduction每个MAX266/265都包含的两个可配置滤波器模块已经显示在数据手册前面的功能框图上。

fclk/fo编程输入（F0-F5）被两个滤波模块共用,然而，每个部分的fo仍然受到各自外接电阻的独立调节。

各个模块的的Q值也是受到各自的外接电阻的独立调节的。

MAX266使用比MAX265更低范围的取样比率（fclk/fo），这样就可以产生更高的信号带宽以及fo的可编程范围。

降低fclk/fo产生的影响主要就是比MAX265的滤波器参数的连续性稍微差了一些，但是这些不同可以通过使用图23所示的图形或是美信得滤波器软件来补偿。

_______________General Description
The MAX1626/MAX1627 step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA to more than 2A. A unique current-limited, pulse-frequency-modulated (PFM) control scheme operates with up to a 100% duty cycle, resulting in very low dropout voltages. This control scheme eliminates minimum load requirements and reduces the supply current under light loads to 90µA (versus 2mA to 10mA for common pulse-width modulation controllers). These step-down controllers drive an external P-channel MOSFET, allowing design flexibility for applications to 12W or higher. Soft-start reduces current surges during start-up. A high switching frequency (up to 300kHz) and operation in continuous-conduction mode allow the use of tiny surface-mount inductors. Output capacitor requirements are also reduced, minimizing PC board area and system costs. The output voltage is preset at 5V or 3.3V for the MAX1626 and adjustable for the MAX1627. Input voltages can be up to 16.5V. The MAX1626/MAX1627 are functional upgrades for the MAX1649/MAX1651.
