7 PE-415 Embedded Eval Kit

The PE-415 allows for further testing and debugging within a prototype system before any commitment to custom fixtures or designs is made. A reference design schematic of the eval kit is freely available to download from the Brainboxes website. The mating board breaks out all ports and functionality to RJ45 or usable headers for ease when developing a proof of concept. Figure 2, Evaluation Kit A <- 4xRJ45 and IDC Style Header B <- Power Consumption Monitoring I. The consumption can be monitored on either the 3.3V line, 5V line or the GND return. II. To monitor the power consumption, break the track along the dotted line. III.

8 Design Guide

8.1 Connectors and pinouts

8.1.1 Ethernet Header (8 Pin)

Figure 3, Ethernet Header Pinout Section 1.3 above details the recommended Pin configuration for the ethernet ports . Coloured CAT5 cable can be wired as shown. For Longer distances (>1.5m) using shielded cable is recommended. Shielding can be attached to the Functional Earth mounting points on the bottom corners of the board Figure 4, 8 Pin 1000BASE-T, Power and LED Connector (Red Wire Indicates Pin 1)

8.1.2 Link LED Header (8 Pin)

Each port has an Activity Indicator LED and an Activity Indicator Output. The output current must be limited through a resistor. The resistor must be selected to limit the maximum draw to 5mA @ 2.5V. The LEDs must be powered from the LED Power Pin. No other devices should be powered through this header. The LEDs function in an active LOW configuration and should be connected as shown below in Figure 5. The Power draw of any supplementary LEDs is in addition to the specified power on the datasheet. Should it be impractical to implement an electronic-based Link LED forwarding, there are holes of ⌀1mm under each indication LED suitable for housing optical fibres or light pipes of a length less than 50cm. Figure 5, External LED Wiring

8.1.3 Mounting Holes

The 4 x M3 mounting holes are Connected to Functional Earth (FE) or Ground (GND) and labelled accordingly. If the device does not share a common ground with the rest of the system it is recommended to use a nonconductive standoff or isolated mounting point.

8.4 Recommended Footprint

Figure 7, PE-515 SMT/THT PCB Footprint The mating LED Header and Port Header are not essential and can be excluded if not required. We recommend using through- hole mating connectors for applications where the module is frequently inserted and removed. Avoid placing components within the 55x55 square occupied by the PE-515 where possible. Where not possible, ensure that the Keepout zones given in the 3D Design resources are strictly adhered to. Failure to do so can potentially cause issues with future compatibility. The device should be given 20mm of clearance from the mating surface. 4 x M3 mounting holes at (0,0), (45,0), (0,45) and (45,45)(GND)

8.5 Routing

When designing custom boards for the PE products, it is important to make considerations for routing the device to connectors or interfaces across a board. Routing Recommendations:

  • Keep Pairs at Uniform distance
  • Keep Pairs at as close a length as possible.
  • Place a GND plane between different pairs
  • Ensure Pairs do not cross plane boundaries

10 Operating Conditions

10.1 Absolute Maximum Ratings

Stresses exceeding absolute maximum ratings may cause permanent damage. Functional performance and device reliability are not guaranteed under these conditions. All voltages are specified with respect to GND. Table 6, Absolute Maximum Rating

10.2 Electrical Characteristics

Table 7 defines the conditions under which we guarantee proper operation of the Pure Embedded Gigabit Switch. Table 7, Typical Electrical Characteristics Sustained operation outside of these conditions will affect long term reliability
