An extended-range Ethernet and clock distribution circuit for distributed sensor networks

This paper describes a high-speed Ethernet-based data and clock network for applications which require an array of multiple sensor nodes distributed over distances of up to 250 m from a central hub. Speeds of up to 100 Mbit/sec and clock skew at the level of 50 ps are achievable using commercially a...

Description
Summary:This paper describes a high-speed Ethernet-based data and clock network for applications which require an array of multiple sensor nodes distributed over distances of up to 250 m from a central hub. Speeds of up to 100 Mbit/sec and clock skew at the level of 50 ps are achievable using commercially available network-grade twisted pair cables and low-power Ethernet transceiver circuits. No fiber optic components are necessary. A specific application of this technology is presented: the ARA neutrino telescope located at the South Pole. © 2012 IOP Publishing Ltd and SISSA.
