The magnetics modules have been specifically designed for implementation of 10/100
Mbps and 100Base-TX data links over data-grade unshielded twisted pair cable (UTP-
5). The modules provide excellent EMI filtering and are targeted for adapter card and
multiport applications. In designing these parts, Pulse has worked closely with mem-
bers of the IEEE 802.3 and ANSI X3.236 committees to develop an analog interface
that provides isolation and EMI filtering for MLT-3 and NRZ transceivers.
The H1090 and H1094 are designed to interface with the MicroLinear ML6692,
ML6694, ML6697, or ML6698 in 10/100 Mbps applications. The H1038 is optimized for
SEEQ or MITEL (formerly GEC Plessy) 10/100 Mbps applications.
The transformers used in the modules provide high voltage isolation, wide
bandwidth, and fast rise time. They utilize stable ferrite materials to minimize the
degradation of primary inductance with base-line wander. At least 350 µH of
inductance will be provided by the transformers in these modules when 0 - 8 mA is
applied across the windings over a temperature range of 0° - 70°C. The High Speed
LAN magnetics modules provide the designer with low cost analog components
for simple and reliable designs. The parts are encased in IC-grade packaging, which
shows superior performance under high temperature solder reflow conditions.
