An Evaluation Board schematic is provided in Figure 17. Table 6 provides the Bill of Materials (BOM) list for Evaluation Board components. An assembly drawing for the Evaluation Board is shown in Figure 18. Layer details are shown in Figure 19. Layer details physical characteristics are noted in Figure 20. Circuit Design ConsiderationsThe following design considerations are general in nature and must be followed regardless of final use or configuration: ∙ Paths to ground should be made as short as possible.∙ The ground pad of the SKY66292-11 has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Because the circuit board acts as the heat sink, it must shunt as much heat as possible from the device.Therefore, design the connection to the ground pad to dissipate the maximum wattage produced by the circuit board. Multiple vias to the grounding layer are required.NOTE: A poor connection between the ground pad and ground increases junction temperature (T J ), which reduces the life of the device.Evaluation Board Test ProcedureTurn-On Sequence1. Connect 50 Ω test equipment or load to the input andoutput RF ports of the Evaluation Board. 2. Connect the DC ground.3. Connect all VCCs and VBIAS lines to a +5 V supply.Connect PAEN to a 2.0 V supply.4. Without applying RF, turn on the 5 V supply, then turn onthe 2 V PAEN.5. Apply RF signal data at –30 dBm and observe that the gainof the device complies with the values in Table 5. Begin measurements.Turn-Off Sequence1. Turn off the RF input to the device.2. Turn off PAEN (set to 0 V).3. Turn off all VCCs and VBIAS.NOTE: It is important to adjust the VCC voltage sources so that +5 V is measured at the board. High collector currents drop the collector voltage significantly if long leads are used. Adjust the bias voltage to compensate.DATA SHEET • SKY66292-11: 2300 TO 2400 MHz HIGH EFFICIENCY 4 W POWER AMPLIFIER203282C -0178 HeaderV CC 3Figure 17.

IntroductionEach device in the Si3474/73/72 family of Power Sourcing Equipment (PSE) controllers is configured into "quads". A quad contains four PSE ports. The Si3474 and Si3473 have two quads while the Si3472 has one. All Si3474/73/72 PSEs can drive 2-pair ports, and the Si3474 can also be configured for 4-pair system operation. The daughtercards (DCs) in this EVB system provide the necessary circuitry to demonstrate the described functionality of each chip. Separate connector boards (CBs) provide the proper wiring for 2-pair or 4-pair operation. The motherboard (MB) powers the system, provides various pushbuttons, DIP switches, connection headers, and programming circuitry to communicate to the PSE on the DC via I2C.The Si3474/73/72 EVB can be jumper-selected (J8) to enable AUTO Pin Autonomous Mode, allowing the PSE to provide power without host software. When using the EVB system, the ports must either all be in 2-pair or 4-pair mode. To use the Si3474/73/72 with a combination of 4-pair and 2-pair ports, the Si3474/73/72 registers must be modified through I2C. The Si3474/73/72 EVB allows access to the Si3474/73/72 registers through a Skyworks CP2112 USB to I2C bridge. A Python interface is provided to allow evaluation with a Windows 10 or later PC.The following table shows the array of PoE support in this evaluation system:Table 1.1. Specifications2. Kit Description and Powering Up the Si3474/73/72 EVB SystemThe Si3474/73/72 EVB system consists of a four-layer daughter card, a four-layer motherboard, and an RJ45 connector board.The daughter card includes the PSE chip, FETs, and the ADDR SEL jumpers. The ADDR SEL jumpers configure the base I2C address that the PSE chip responds to. Each PSE quad responds to an individual I2C address, as described in Table 2.1 I2C Address Selection Table on page 5.Figure 2.1. Si3474/73/72 MB-EVB Motherboard, Daughter Card, and RJ45 Connector BoardFigure 2.2. Si3474DC-EVB Daughter CardFigure 2.3. ADDR SEL Configuration Header Table 2.1. I2C Address Selection TableThe behavior of the status LEDs on the Si3474/73/72 EVB MB is described in the figure below.Figure 2.4. Status LEDsThe behavior of the buttons on the Si3474/73/72 EVB MB is described in the figure below.Figure 2.5. Buttons2.1 Si3474/73/72 EVB Motherboard OverviewThe Si3474/73/72 EVB motherboard consists of:•Status LEDs•Terminal blocks for power•USB connector•AUTO mode selection jumpersThe RJ45 connectors are located on the connector board (POE-BT-CB for 4-pair operation and POE-BT-2P-CB for 2-pair operation). The connector board also has jumpers allowing configuration of the RJ45 connectors for either 802.3bt 4-pair port usage or for 802.3at 2-pair port usage.2.2 Use CasesThe following sections describe the most common use cases for the USB connector, terminal blocks, AUTO mode selection jumpers, and the connector board jumper connections from a system perspective.Refer to the appendix if you have PoE-BT-CB Rev 1.0 or are not sure which revision you have.2.2.1 Unhosted (AUTO Pin Autonomous Mode)2.2.1.1 2-Pair ModeThe following figure shows the use case where the Si3474, on the Si3474DC-EVB daughter card, is used as a 2-pair PSE without an I2C host. The JP2 AUTO MODE SEL in this case can be set to either Position 7 or Position 6. The corresponding selection jumpers on the PoE-BT-CB connector board will need to be set in an alternating fashion so that the eight 802.3at ports can drive the RJ45 jacks as shown. The VPWR polarity of the top-row RJ45 jacks has an opposite polarity relative to the ports on the bottom-row RJ45. Two power supplies are needed for this configuration. The +54 V provides power to powered devices (PDs) and to the Si3474 VPWR. The +5 V supply powers the Si3474 VDD via isolated dc-dc converter.Figure 2.6. Si3474 No I2C Host, Eight 2-Pair PortsFigure 2.7 shows the Si3472, on the Si3472DC-EVB daughter card, using the 2-pair PoE-BT-2P-CB connector board without an I2C host. In this case the JP2 jumper is set for 2-pair, Class 3, 15W operation but can be set for any of the classes listed. On the PoE-BT-2P-CB, the ports are configured for Alternate A (Alt-A) operation. Each port can be configured to use Alt-A or Alt-B pairs, depending on whether you’re operating as an endspan or midspan PSE. Alt-A is the typical choice for endspan and Alt-B for midspan. The power supplies are the same as listed for the Si3474; +54V to power attached PDs and +5V for the Si3472.The Si3473 is not illustrated but has the same configuration as the Si3472. The Si3473 can drive all 8 ports of the PoE-BT-2P-CB connector board while the Si3472 can only drive the first four.Figure 2.7. Si3472, No I2C Host, Four 2-Pair PortsThe configuration for the Si3472 and Si3473 is similar except for the connector board. The following figure shows the Si3472 daughter card paired with the PoE-BT-2P-CB connector board. Endspan or midspan operation is selectable by switching between Alt-A and Alt-Brespectively. Here Alt-A has been selected on all ports except for Port 1, which is set for Alt-B operation.Figure 2.8. Si3472 I2C Hosted2.2.1.2 4-Pair ModeThe figure below shows the use case where the Si3474 is used as a 4-pair PSE without an I2C host. The JP2 AUTO MODE SEL in this case can be set to either Position 1, 2, 3, 4, or Position 5, depending on the desired level of power allocation, as described in the figure. The corresponding selection jumpers on the PoE-BT-CB will need to be set to all "Top" positions. Four of the RJ45 jacks will be active while the other four RJ45 jacks are not connected.It is also possible to configure the jumpers to all "BOT" instead of all "TOP" (then use the bottom RJ45 jacks). When using the bottom RJ45s, the VPWR polarity will be inverted relative to when using the top RJ45 jacks. Two power supplies are needed for this configuration. The +54 V provides power to PDs as well as to the Si3474 VPWR. The +5 V supply is used to supply power to the Si3474 VDD, albeit indirectly through isolation via an isolated dc-dc converter.Figure 2.9. Si3474 No I2C Host, Four 4-Pair Ports2.2.2 I 2C HostedThe following figure shows the use case where the Si3474 is controlled by an I 2C host. In this case, all JP2 AUTO MODE SEL jumpers are removed to indicate a hosted I 2C operation mode. The selection jumpers on the PoE-BT-CB will need to be set up, depending on the expected programming of bits 4 and 7 of Register 0x29 on both quads. One power supply is needed for this configuration. The +54V provides power to PDs as well as to the Si3474 VPWR. The JP1 jumper is placed so that the +5 V supply is derived from USB. The 5V USB rail supplies power to the Si3474 VDD via isolated dc-dc converter.Figure 2.10.
