The XPort embedded device server is a complete network-enabling solution enclosed
within an RJ45 package. This miniature serial-to-Ethernet converter empowers
original equipment manufacturers (OEMs) to quickly and easily go to market with
networking and web page serving capabilities built into their products.
The XPort
The XPort contains Lantronix’s own DSTni controller, with 256 Kbytes of SRAM,
16 Kbytes of boot ROM, and integrated AMD 10/100 PHY.
The XPort also contains the following:
3.3-volt serial interface
All I/O pins are 5V tolerant
4-Mbit flash memory
Ethernet magnetics
Power supply filters
Reset circuit
+1.8V regulator
25-MHz crystal and Ethernet LEDs
The XPort requires +3.3-volt power and is designed to operate in an extended
temperature range (see technical data).

PCB Interface
The XPort has a serial port compatible with data rates up to 920 kbps (in high-
performance mode). The serial signals (pins 4–8) are 3.3V CMOS logic level, and 5V
tolerant. The serial interface pins include +3.3V, ground, and reset. The serial
signals usually connect to an internal device, such as a UART. For applications
requiring an external cable running with RS-232 or RS422/485 voltage levels, the
XPort must interface to a serial transceiver chip.

Recommended PCB Layout
The hole pattern and mounting dimensions for the XPort device server are shown in
the following drawing. For proper heat dissipation, it is recommended that the PCB
have approximately 1 square inch of copper attached to the shield tabs. The shield
tabs are an important source of heat sinking for the device.
The XPort shield is considered “chassis ground” and should be separate from “signal
ground”. ESD near the XPort at the panel opening will likely jump to the shield.
We recommend using high voltage (~200V), low ESR, 0.01uF capacitors to connect
chassis ground to both signal ground and 3.3V. This will cause any voltage spike
from ESD to be imparted equally to both signal ground and 3.3V with no net voltage
increase between 3.3V and signal ground. For the highest level of ESD protection of
the XPort, it is recommended that the shield not be directly connected to signal GND.
The metal shield fingers around the XPort’s RJ45 should physically contact the
product housing when the housing is metal, or metallic coated.
The shield is also a heat sink for the internal EX Processor. As in all heat sinking
applications, the more copper connected to the heat sink the better. Adding 1 inch
square inch of copper flood on the PCB is adequate to allow the XPort to work up to
+85°C. If the application does not expect to see t emperatures up to +85°C the heat
sink may be smaller than 1 square inch.
