MAX3969 光电接收器限幅器说明书

General DescriptionThe MAX3969 limiting amplifier with PECL data outputs is ideal for low-cost ATM, Fast Ethernet, FDDI and ESCON fiber optic receivers.The MAX3969 features 1mV P-P input sensitivity and an integrated power detector that senses the input signal power. It provides a received-signal-strength indicator (RSSI), which is an analog indication of the power level.Signal strength is also indicated by the complementary TTL loss-of-signal (LOS) outputs and the PECL signal-detect (SD) output, both of which indicate the power level relative to a programmable threshold.The threshold can be adjusted to detect signal ampli-tudes as low as 2.7mV P-P . An optional squelch function disables switching of the data outputs by holding them at a known state when the signal is below the pro-grammed threshold.The MAX3969 is available in die form and a 4mm x 4mm, 20-pin thin QFN package.ApplicationsSFP/SFF TransceiversFast Ethernet/FDDI Transceivers 155Mbps LAN ATM Transceivers ESCON Receivers FTTx TransceiversFeatures♦1mV P-P Input Sensitivity♦Loss-of-Signal Detector with Programmable Threshold ♦TTL LOS and PECL Signal Detect♦Analog Received-Signal-Strength Indicator ♦Output Squelch Function♦Compatible with 4B/5B Data CodingMAX3969200Mbps SFP Limiting Amplifier________________________________________________________________Maxim Integrated Products1Ordering InformationTypical Application CircuitsFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .temperature (T J ) range, but are tested and guaranteed only at T A = +25°C.Typical Application Circuits continued at end of data sheet.Pin Configuration appears at end of data sheet.M A X 3969200Mbps SFP Limiting Amplifier 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Functional DiagramDetailed DescriptionThe MAX3969 contains a series of limiting amplifiers and power detectors, offset correction, data-squelch circuitry, TTL buffers for LOS outputs, and PECL output buffers for signal detect (SD) and data outputs. See Figure 1 for the functional diagram.Gain Stages and Offset CorrectionA cascade of limiting amplifiers provides approximately 65dB of combined small-signal gain. The large gain makes the amplifier susceptible to small DC offsets in the signal path. To correct DC offsets, the amplifier has an internal feedback loop that acts as a DC autozerocircuit. By correcting the DC offsets, the limiting amplifi-er sensitivity and power-detector accuracy are improved.The offset correction is optimized for data streams with a 50% duty cycle. A different average duty cycle results in increased pulse-width distortion and loss of sensitivi-ty. The offset-correction circuitry is less sensitive to vari-ations of input duty cycle (for example, the 40% to 60%duty cycle encountered in 4B/5B coding) when the input is less than 30mV P-P .The data inputs must be AC-coupled for the offset cor-rection loop to function properly. Differential input impedance is >5k Ω.M A X 3969Power DetectorEach amplifier stage contains a logarithmic FWD, which indicates the RMS input signal power. The FWD outputs are summed together at the FILTER pin where the sig-nal is filtered by an external capacitor (C FILTER ) con-nected between FILTER and V CC . The FILTER signal generates the RSSI output voltage (V RSSI ), which is proportional to the input power in decibels. When LOS is low, V RSSI is approximated by the following equation:V RSSI (V) = 1.2V + 0.5log (V IN )where, V IN is the data input voltage measured in mV P-P .This relation translates to a 25mV increase in V RSSI for every 1dB increase in V IN . The RSSI output is reduced approximately 120mV when LOS is high.Typically the RSSI output is connected to an A/D con-verter for diagnostic monitoring. This output can be left open if not required in the application. The RSSI output is designed to drive a minimum load resistance of 10k Ωto ground, and a maximum capacitance of 10pF. A 10k Ωseries resistor is required to buffer loads greater than 10pF.Signal-Strength ComparatorA comparator is used to indicate the input signal strength relative to a user-programmable threshold.One of the comparator inputs is connected to the RSSI output signal, and the other is connected to the thresh-old voltage (V TH ), which is set externally and provides a trip point for signal-strength indication. When the sig-nal strength is above the threshold, the SD output asserts high and the LOS output deasserts low.Likewise, when the signal strength falls below the threshold, SD deasserts low and LOS asserts high. To ensure chatter-free operation, the comparator is designed with approximately 5dB of hysteresis.SquelchThe squelch function disables the data outputs by forc-ing OUT- low and OUT+ high when the input signal is below the programmed threshold. This function ensures that when there is a loss of signal, the limiting amplifier and all downstream devices do not respond to input noise. Connect SQUELCH to GND or leave it unconnected to disable squelch. Connect SQUELCH to V CC to enable squelch.PECL OutputsThe data outputs (OUT+, OUT-) and signal-detect out-put (SD) are supply-referenced PECL outputs. See Figure 2 for the equivalent output circuit.Both data outputs must be terminated for proper opera-tion, but the SD output can be left open if not required in the application. The proper termination for a PECL output is 50Ωto (V CC - 2V), but other standard termina-tion techniques can be used. For more information on PECL terminations and how to interface with other logic families, refer to Maxim Application Note HFAN-01.0:Introduction to LVDS, PECL, and CML.TTL OutputsThe LOS outputs (LOS, LOS ) are implemented with open-collector, Schottky-clamped, ESD-protected, TTL-compatible outputs. See Figure 3 for the equivalent out-put circuit. The LOS outputs require external pullup resistors for proper operation. Resistor values between 4.7k Ωand 10k Ωare recommended.If the LOS outputs are not required for the application,they can be left open.Design ProcedureProgram the Power-Detect ThresholdThe suggested procedure for setting the power-detect threshold is given below and is illustrated in Figure 4.1)Determine the maximum receiver sensitivity(RX_MAX) in dBm and the PIN-TIA responsivity (G)in V/W.2)Calculate the differential voltage swing (VIN_SEN) atthe MAX3969 inputs while operating at sensitivity.V IN_SEN = 10(RX_MAX / 10)x 2 x G3)Calculate the threshold voltage (V IN_TH ) at whichLOS must be low (SD must be high) by allowing 3.6dB (1.8dB optical) margin for power-detector accuracy.V IN_TH = V IN_SEN x 0.664)Use V IN_TH and the line labeled (SD H IGH / LOSLOW) in the Power-Detect Threshold vs. R2 graph in the Typical O perating Characteristics to deter-mine the value of R2. Select R1=100k Ω.200Mbps SFP Limiting Amplifier 6_______________________________________________________________________________________Select C FILTERFor SFP/SFF, FDDI, 155Mbps ATM LAN, Fast Ethernet,and ESCON receivers, Maxim recommends C FILTER =0.01µF. This capacitor value ensures chatter-free LOS/SD and provides a typical assert/deassert time of 10µs. For other applications, the value of C FILTER can be calculated using the following equation:C FILTER = τ/ 825Ωwhere τis the desired time constant of the power detector.Select C AZ and C INExternal-coupling capacitors (C IN ) are required on the data inputs for the offset correction loop to function properly. The offset correction loop bandwidth is deter-mined by the external capacitor (C AZ ) connected between CZP and CZN. The poles associated with C IN and C AZ must work together to provide a flat response at the lower -3dB corner frequency. For SFP/SFF, FDDI,155Mbps ATM LAN, Fast Ethernet, and ESCON receivers, Maxim recommends the following:C IN = 4700pF C AZ = 1µFMAX3969200Mbps SFP Limiting Amplifier_______________________________________________________________________________________7Figure 2.

关于光纤收发器的基础知识解析

关于光纤收发器的基础知识解析光纤收发器是网络数据传输中必不可缺少的一种设备，那么什么是光纤收发器呢，光纤收发器的分类是怎样，光纤收发器有怎样的特点，以及光纤收发器的连接方式和发展趋势是怎样的呢？下面就让我们一一来解析光纤收发器的基础知识吧。

光纤收发器光纤收发器，是一种将短距离的双绞线电信号和长距离的光信号进行互换的以太网传输媒体转换单元，在很多地方也被称之为光电转换器（Fiber Converter）。

产品一般应用在以太网电缆无法覆盖、必须使用光纤来延长传输距离的实际网络环境中，且通常定位于宽带城域网的接入层应用；同时在帮助把光纤最后一公里线路连接到城域网和更外层的网络上也发挥了巨大的作用。

一、分类目前国外和国内生产光纤收发器的厂商很多，产品线也极为丰富。

为了保证与其他厂家的网卡、中继器、集线器和交换机等网络设备的完全兼容，光纤收发器产品必须严格符合10Base-T、100Base-TX、100Base-FX、IEEE802.3和IEEE802.3u等以太网标准，除此之外，在EMC防电磁辐射方面应符合FCC Part15.时下由于国内各大运营商正在大力建设小区网、校园网和企业网,因此光纤收发器产品的用量也在不断提高，以更好地满足接入网的建设需要。

1,按光纤性质分类单模光纤收发器:传输距离20公里至120公里多模光纤收发器：传输距离2公里到5公里如5公里光纤收发器的发射功率一般在-20~-14db之间，接收灵敏度为-30db,使用1310nm的波长；而120公里光纤收发器的发射功率多在-5~0dB之间，接收灵敏度为-38dB,使用1550nm的波长。

，2,按所需光纤分类单纤光纤收发器：接收发送的数据在一根光纤上传输双纤光纤收发器：接收发送的数据在一对光纤上传输顾名思义，单纤设备可以节省一半的光纤,即在一根光纤上实现数据的接收和发送，在光纤资源紧张的地方十分适用。

这类产品采用了波分复用的技术，使用的波长多为1310nm 和1550nm.但由于单纤收发器产品没有统一国际标准，因此不同厂商产品在互联互通时可能会存在不兼容的情况。

光纤区别-单模和多模-光端机和光纤收发器的区别-总结贴

光纤区别-单模和多模-光端机和光纤收发器的区别-总结贴按光在光纤中的传输模式可分为：单模光纤和多模光纤um=1微米=0.001毫米多模光纤的纤芯直径为50~62.5μm，包层外直径125μm，单模光纤的纤芯直径为8.3μm，包层外直径125μm。

光纤的工作波长有短波长0.85μm、长波长1.31μm和1.55μm。

光纤损耗一般是随波长加长而减小，0.85μm的损耗为2.5dB/km,1.31μm的损耗为0.35dB/km，1.55μm的损耗为0.20dB/km，这是光纤的最低损耗，波长1.65μm以上的损耗趋向加大。

由于OHˉ的吸收作用，0.90~1.30μm和1.34~1.52μm范围内都有损耗高峰，这两个范围未能充分利用。

80年代起，倾向于多用单模光纤，而且先用长波长1.31μm。

多模光纤多模光纤(Multi Mode Fiber)：中心玻璃芯较粗(50或62.5μm)，可传多种模式的光。

但其模间色散较大，这就限制了传输数字信号的频率，而且随距离的增加会更加严重。

例如：600MB/KM的光纤在2KM时则只有300MB 的带宽了。

因此，多模光纤传输的距离就比较近，一般只有几公里。

单模光纤单模光纤(Single Mode Fiber)：中心玻璃芯很细(芯径一般为9或10μm)，只能传一种模式的光。

因此，其模间色散很小，适用于远程通讯，但还存在着材料色散和波导色散，这样单模光纤对光源的谱宽和稳定性有较高的要求，即谱宽要窄，稳定性要好。

后来又发现在1.31μm波长处，单模光纤的材料色散和波导色散一为正、一为负，大小也正好相等。

这就是说在1.31μm波长处，单模光纤的总色散为零。

从光纤的损耗特性来看，1.31μm处正好是光纤的一个低损耗窗口。

这样，1.31μm波长区就成了光纤通信的一个很理想的工作窗口，也是现在实用光纤通信系统的主要工作波段。

1.31μm常规单模光纤的主要参数是由国际电信联盟ITU－T在G652建议中确定的，因此这种光纤又称G652光纤二、单模和多模的技术是同时产生的吗？是不是哪个更先进多模先谈不上那个更先进，一般距离近的用多模，远的只有用单模的，因为多模光纤的收发器比单模的便宜很多三、单模光纤用于长途的传输，多模光纤用于室内数据传输吧长途只能用单模，但是室内数据传输不一定都要用多模四、服务器和存储设备用的光纤是单模还是多模的多半用的是多模，因为偶只是搞通讯光纤对这个问题不是太清楚。

光纤收发器分类_光纤收发器ab端的区别

光纤收发器分类_光纤收发器ab端的区别光纤收发器，是一种将短距离的双绞线电信号和长距离的光信号进行互换的以太网传输媒体转换单元，在很多地方也被称之为光电转换器（Fiber Converter）。

产品一般应用在以太网电缆无法覆盖、必须使用光纤来延长传输距离的实际网络环境中，且通常定位于宽带城域网的接入层应用；如：监控安全工程的高清视频图像传输；同时在帮助把光纤最后一公里线路连接到城域网和更外层的网络上也发挥了巨大的作用。

光纤收发器分类性质分类单模光纤收发器：传输距离20公里至120公里多模光纤收发器：传输距离2公里到5公里如5公里光纤收发器的发射功率一般在-20～-14db之间，接收灵敏度为-30db，使用1310nm 的波长；而120公里光纤收发器的发射功率多在-5～0dB之间，接收灵敏度为-38dB，使用1550nm的波长。

所需分类单纤光纤收发器：接收发送的数据在一根光纤上传输双纤光纤收发器：接收发送的数据在一对光纤上传输顾名思义，单纤设备可以节省一半的光纤，即在一根光纤上实现数据的接收和发送，在光纤资源紧张的地方十分适用。

这类产品采用了波分复用的技术，使用的波长多为1310nm 和1550nm。

但由于单纤收发器产品没有统一国际标准，因此不同厂商产品在互联互通时可能会存在不兼容的情况。

另外由于使用了波分复用，单纤收发器产品普遍存在信号衰耗大的特点。

工作层次/速率100M以太网光纤收发器：工作在物理层10/100M自适应以太网光纤收发器：工作在数据链路层按工作层次/速率来分，可以分为单10M、100M的光纤收发器、10/100M自适应的光纤收发器和1000M光纤收发器以及10/100/1000自适应收发器。

其中单10M和100M的收发器。
