Highest Transmission Data Rate on Long Cable Intel SHDSL Evaluation Kit

With the SHDSL standard, data can be transmitted over extremely long copper cables. This makes this technology the first choice in applications where Power over Ethernet and DSL technologies like G.FAST, VDSL are not possible. With its SHDSL Evaluation Kit, Würth Elektronik now offers developers the possibility to test applications with the SHDSL transceiver from Intel.

Typical applications are video surveillance, infotainment systems in airports and subway stations, vending machines, bank terminals, traffic control systems and industrial communication systems. It can cover distances of up to 15 kilometres and achieve data rates of up to 15 Mbps using twisted-pair copper wires A throughput of 60Mbps (symmetrical rate) has also been achieved using 4 copper pairs (a CAT5e cable has 4 copper pairs).

The evaluation board included in the kit can be used as an EFM modem, SHDSL EFM module or plug & play Ethernet extender. It has a selectable bit rate including auto mode and USB-EIA232 emulation or TTL compatible EIA232 interface. There are over 122 components from Würth Elektronik used on this board such as the LAN transformer, PMI inductor, ferrites, LEDs, capacitors, connectors and switches.

The board also includes a custom transformer  The board also includes a custom transformer “It is customized to be compact (17.7 x 13.4 x 12.7mm height) and provides very good total harmonic distortion. This transformer meets UL and IEC standards, has a low leakage inductance (less than 35µH) and offers excellent longitudinal balance”, explained Swaroop Vaidyanath, Product Manager of this kit. The kit contains the evaluation board with the Intel chipset, two CAT6 Ethernet cables, a micro-USB cable and a guide for the first steps.
