Application Notes
Pulse’s 10Base-T interface module provides the complete
analog solution for maintaining high data integrity in
transmissions between multiport hubs, and individual stations,
(ports, nodes). Hubs and stations utilizing these modules fully
meet the requirement of IEEE 802.3i-1993 standards and
operate at a full 10 Mbps data rate over 100 meters of cable.
Both transmit and receive channels of PE-68011 consist of low
pass filters, isolation transformers and common mode chokes.
They provide three basic functions: EMI suppression,
impedance matching and equipment isolation.
Compliance with IEEE standards can be achieved by applying
rigorous design guidelines to suppress EMI and crosstalk
interferences as well as control both signal jitter and reflections.
PE-68011 controls these features by creating the optimum
signal shape and spectral content. At system level, these noise
mechanisms may be reduced by optimizing high frequency
signal paths and utilizing good PCB grounding techniques.
PE-68011, with higher order low pass filters and high impedance
common mode chokes, significantly helps to minimize noise to
the lowest possible level. Each part is fully tested to provide
2000 Vrms breakdown protection from static charge which may
develop on the twisted pair line.
Modules are shipped in tubes unless tape & reel is specified.
Please add the suffix “T” (i.e. PE-68011T) for tape & reel orders
(increments of 450 pcs required).
