Application Notes
The PE-69024, PE-69025, PE-69025-001, and 78Z9022SM mag-
netics modules have been specifically designed for implementa-
tion of the 100 Mbps 100Base-T4 data links over voice-grade
unshielded twisted pair UTP-3 cable. The modules provide excel-
lent EMI filtering and are targeted for multiport concentrators and
adapter card applications. In designing these parts, Pulse has
worked closely with the Fast Ethernet Alliance to develop an ana-
log interface that provides isolation and EMI filtering for 100Base-
T4 transceivers.
The transformers used in the modules provide high voltage
isolation, wide band width and fast rise times. Each
channel includes a low pass filter which reduces over-shoot
and ringing on the transmitted waveform and decreases suscepti-
bility to noise picked up by the cable. The filter and magnetic
characteristics are also suitable for 10 Mbps transmission allow-
ing the module to be shared for 10/100 Mbps ports (Check
transceiver specifications for 10/100 Mbps capability). The low
pass corner frequency has been optimized to provide high attenu-
ation in the stop band. The modules provide over -27 dB of atten-
uation at 30 MHz to filter signal harmonics and reduce EMI.
The modules interface to either a current source (PE-69025 and
78Z9022SM) or a voltage source (PE-69024) transceiver. The
PE-69024, PE-69025, PE-69025-001, and 78Z9022SM are 30 pin
surface mount packages including filter and magnetics for all four
channels or one module per data link.

tions, contact Pulse’s HS LAN marketing group at (619) 674-8100.
