Description
PE-67566
The PE-67566, PCMCIA compatible filter magnetics module has
been designed to interface with the transmit side of Texas
Instruments’ TI380C60 transceiver chip or TI380C30 integrated
commprocessor/transceiver chip. This module provides impedance
matching, signal isolation, and signal conditioning. It is fully compliant
with the IEEE 802.5 requirements.
PE-67567
The PE-67567 transformer and choke module has been designed to
interface with the receive side of Texas Instruments’ TI380C60 trans-
ceiver chip or TI380C30 integrated commprocessor/transceiver chip.
This PCMCIA compatible module provides impedance matching,
signal isolation and EMI suppression. The PE-67567 is fully compliant
with the IEEE 802.5 requirements.
PE-67585, PE-67595
The PE-67585 and PE-67595 are complete transmit and receive
interface modules for the Texas Instrument TI380C60 transceiver chip
and TI380C30 integrated commprocessor/transceiver chip. Fully

SURFACE MOUNT FILTER
MAGNETIC MODULES
For Token Ring Applications
Application Notes
Pulse’s filter magnetic modules have been designed for use
with Texas Instruments’ IEEE-802.5 compliant transceiver
chips, TI380C60 and TI380C30. The referenced application
circuits should serve as a starting point for design. To reduce
induced noise, attention should be given to the layout of the
Token Ring interface circuitry, especially to the selection of
components and their placement.
The Token Ring transceiver provides a 150
Ω
impedance to
the transceiver IC’s output driver. The 1:1 isolation trans-
former interfaces the IC driver to a 150
Ω
low pass filter. The
line isolation transformer also provides taps for 100
Ω
media
connections. The cut-off frequency and phase characteristics
of this filter are precisely controlled to maximize the attenua-
tion of signal harmonics above 30 MHz, while minimizing sig-
nal delay distortion.
The receive channel consists of a line isolation transformer
with turns ratio of 1:1 for 150
Ω
media. The line isolation
transformer also provides taps for 100Ω media connections.
The common mode choke prevents impulse noise, picked up
from the media, from entering the IC receiver input. Common
mode filter circuitry is included in both transmit and receive
channels for improved EMI suppression.
Do not connect to both the UTP (100
Ω)
and STP (150
Ω)
simultaneously The modules have been optimized to support
only one media connection at a time. All pins that are unspec-
ified or not in use should be left unconnected.
Depending on the EMI characteristics of the board layout,
addtional common mode suppression may be necessary.
Please contact Pulse for information on Token Ring Filter
Magnetic Modules.
