LTC4263CS LTC4263CDE 示例电路981A B主板, 单端口自主PSE DAUGHT
LTC4263 in single port Power Over Ethernet (PoE) Power Sourcing Equipment (PSE) Midspan and End-point solutions. The LTC4263 is an autonomous sin-gle-channel PSE controller for use in IEEE802.3af compliant PoE systems. It includes an on-board pla-nar power MOSFET, internal inrush, current limit, and short circuit control, Powered Device (PD) detection and classification circuitry, and selectable AC or DC disconnect sensing. On-board control algorithms provide complete PSE Control operation without the need of a microcontroller. The LTC4263 simplifies ply and a small number of passive support compo-nents. Other options shown on the DC981A include Legacy PD detection enable, Midspan back off timer enable, power class enforce mode, power manage-ment enable. An LED for each port is driven by the respective LTC4263 to indicate the state of the port. Design files for this circuit board are available. Call the LTC factory.LTC is a trademark of Linear Technology CorporationTable 1. Typical DC981 Performance Summary (T A = 25°C)PARAMETER CONDITION VALUE Supply Voltage Voltage for IEEE802.3af Compliance at Port Output 46V to 57V Midspan Mode Detection Backoff Midspan Enabled, Failed Detection 3.2 seconds Detection Range Valid IEEE802.3af PD Detection 17k to 29.7k Set Maximum Allocated Power Power Management Enabled 17WEthernet Powered Pairs Pinout Endpoint PSE, Alternative A (MDI)Midspan PSE, Alternative B1/2(+), 3/6(-)4/5(+) , 7/8 (-)QUICK START PROCEDUREDemonstration circuit 981 is easy to set up to evaluate the performance of the LTC4263. Refer to Figure 2 for proper measurement equipment setup and follow the procedure below.1.Place jumpers in the following positions:ENENDISACACEN 2.Insert daughter card (DC981B) to main board (DC981A) at polarized connector J3.3.Apply 48V across VDD48 and VSS.4.Connect a scope probe at VOUT_MD and VOUT_EP both referenced to positive rail VDD48.5.Connect a valid PD to either Midspan PSE or Endpoint PSE.6.Connect a second PD to the open port.JP1 JP2 JP3 JP4 JP5 JP6Figure 1.Basic DC981A/B Equipment Setupto power the board. This in turn provides power to the Midspan PSE and Endpoint PSE outputs. On each solution, an LTC4263 provides detection of a PD, classification, power management, safe power on of the PD, port current limit, and disconnect detection. Midspan PSE and Midspan ModeIn the Midspan solution, a device (router, switch, etc.) that does not have PoE is connected to MIDSPAN IN. Data is passed through to MIDSPAN OUT along with PoE which goes out to a PD. Power is applied di-rectly to Ethernet pairs 4/5 and 7/8. The LTC4263 circuitry sits in a small layout area behind the RJ45 connector and switches power on the negative rail. To show the different functions of the LTC4263, jumpers allow for the user to select the options of AC or DC disconnect, legacy detection, Midspan backoff timing, and class enforcement. An LED that shows the status of the port is driven by a switcher in the LTC4263 to improve efficiency when VDD5 is pro-vided internally. Push button switch SW1 ties the shutdown pin to ground to disable the LTC4263 in the Midspan solution.A PSE implementing AlternativeB pin out must back off from detection for at least 2 seconds after a failed attempt. This is to avoid conflict of Detection, for ex-ample, should a potential Endpoint PSE and Midspan PSE be connected to the same PD. To enable this feature, set JP2 to DIS. JP2 ties the MIDSPAN pin to VDD5 to enable the LTC4263 backoff timer or to VSS to disable. A 3.2 second delay occurs after every failed detect cycle unless the result is open circuit. If held at VSS, no delay occurs after failed detect cycles. Endpoint PSEThe Endpoint solution is primarily shown on a small daughter card (DC981B). This card is the same height and width as the integrated RJ45 connector that it slides behind on the main board (DC981A). The RJ45 includes Ethernet magnetics and common ter card are VSS, VDD48 and VOUT. Power is switched over from the daughter card out to the Ethernet data pairs (1/2 and 7/8). A PHY can be con-nected to the “TO PHY” to pass data through to the data pairs along with PoE. LED drive and power management pins are also brought out for additional board functions. The board is set up for AC discon-nect, but can be reworked for DC disconnect by re-moving components and replacing with shorts in cer-tain locations. Two solder jumpers also provide se-lectable options for legacy detection and class en-force.Power ManagementThe Midspan and Endpoint PSE, although separate solutions on the DC981, are tied together at the PWRMGT pin for demonstration of the LTC4263 power management capability. Programmable on-board power management circuitry allows multiple LTC4263s to allocate and share power in multi-port systems, allowing maximum utilization of the 48V power supply – all without the intervention of a host processor.The LTC4263 sources current at the PWRMGT pin proportional to the class of the PD that it is powering. The voltage of this pin is checked before powering the port. The port will not turn on if this pin is more than 1V above VSS. The PWRMGT pins of the LTC4263s are tied together and connect to a resistor (RPM) and capacitor (CPM) in parallel to VSS to implement power management among multiple ports. This re-sistor is selected with the following equation:RPM= 213k * W / PFULL_LOADOn the DC981A, the default RPMis 12.4k for a full load power of 17W.19 33 73*RPM= 12.4kTable 3.

If held at VDD5, the LTC4263 will reduce the ICUT threshold for Class 1 or Class 2 PDs. If ENFCLS is held at VSS, ICUT remains at 375mA (typical) for all classes. Table 4.

When the port is powered, the LED is on; when disconnected or detecting, the LED is off. If an invalid signature is detected or a fault occurs, the LED will flash a pattern that the user or host sys-The logic 5V power supply can be supplied from the internal LTC4263 5V supply or an external 5V supply when above the internal supply. If the internal regula-tor is used, this pin should only be connected to the bypass capacitor and to any logic pins of the LTC4263 that are being held at VDD5.AC and DC DisconnectAC and DC disconnect are two different methods of detecting whether a valid PD is present and requires power. AC disconnect is the default method for the DC981 but can be converted to DC disconnect in the Midspan solution through two jumpers. Moving DISCON (JP4) to DC will short the ACCOUT pin to VSS and configure the LTC4263 to DC disconnect. Moving jumper setting for ACCOMP (JP5) to DC by-passes the AC blocking diode and removes the RC used for AC disconnect from the main circuit. Legacy DetectionLEGACY jumper JP3 controls whether legacy detect is enabled. If the LEGACY pin is held at VDD5 (EN se-lected), legacy detect is enabled and testing for a large capacitor is performed to detect the presence of a legacy PD on the port. If held at VSS (DIS se-lected), only IEEE 802.3af compliant PDs are de-tected. If left floating (no jumper), the LTC4263 enters force-power-on mode and any PD that generates be-tween 1V and 10V when biased with 270µA of detec-tion current will be powered as a legacy device. This mode is useful if the system uses a differential detec-tion scheme to detect legacy devices. Warning: Leg-acy modes are not IEEE 802.3af compliant.Figure 2.DC981 Options。

专有2.4-GHz的无线音频设计方案
1.引言计的信号范围、音质和最长播放时间方面面临着重大挑战。
为满足这些要求，工程师可以利用来自多家制造商的大量可用产品，包括（按字母顺序）Analog在典型的无线娱乐系统（图1）中，源信号通过带有可选范围扩展器的无线射频接口传输到播放器系统，例如立体声耳机或扬声器。
在播放器内，相应的无线射频接口接收信号以供编解码器、音频处理器或 DSP 处理，以创建驱动到扬声器的最终模拟信号。
一个适当的电源，通常包括一个电池和充电管理电路，完成了系统。
子系统的可用集成解决方案可以帮助工程师满足这些要求，同时降低设计复杂性和成本。
2.频带遗留问题、市场接受度和未授权带宽的可用性通常会推动无线电通信频率的选择。
同时，满足增加操作范围和延长电池寿命的要求为有用频段设置了界限。
对增加功率的需求是对更远距离操作的渴望的自然结果，但射频波长的选择在平衡范围和功率方面起着至关重要的作用。
射频波长和范围之间的关系在Friis 传输方程中进行了描述：其中Pt = 发射功率Pr = 接收功率Gt = 发射器天线增益Gr = 接收器天线增益λ = 波长d = 发射器和接收器之间的距离对于统一参数，距离成为波长的简单线性函数，因此更长波长的无线电通信等同于更大的范围。
当然，更长的波段面临着包括干扰和有效载荷带宽在内的问题。
在这种情况下，2.4 GHz ISM 频段在实际范围限制和有用带宽之间提供了良好的平衡。
2.4 GHz 解决方案的吸引力在于它们能够以低功耗提供有用的有效范围，以及它们的全球可用性。
在蓝牙等标准中使用的基于跳频扩频（FHSS）的2.4 GHz 设计具有在高度活跃的无线电环境中相对不受干扰信号影响的优势。
与较低的ISM 频段相比，这些系统还提供足够的数据带宽，以允许高质量立体声的数字传输，后者通常仅限于模拟或较低数据速率的数字音频。
蓝牙标准工作频率为 2.4 GHz，非常适合消费者的连接要求。
它的广泛使用使得基于蓝牙的无线音频播放器很可能会找到兼容的音频主机，例如计算机、笔记本电脑、平板电脑和智能手机。
