10BASE-T QUAND SMT
TRANSFORMER MODULES
Pulse’s 10BASE-T Quad SMT transformer modules are designed to
interface with transceiver chips offered with internal wave shaping and
filtering. Pulse developed the modules working closely with IC chip vendors
for this “filter-on-chip” application such as: AMD, Crystal, Level One,
National Semiconductor and Texas Instruments. The Pulse modules are
available with varying turns ratios optimized for available transceiver chips.
A cross-reference table listing chip vendor and part number by Pulse part
number is illustrated below.
The Pulse modules offer different levels of electrical performance to meet
all applications.
The Pulse PE-68065L contains transmit and receive isolation transformers
to maintain signal integrity, suppress common mode noise, and supply
equipment isolation per the IEEE 802.3 standard.
The Pulse PE-68062LNL and E5002NL provide transmit and receive isolation
transformers as well as the high impedance common mode chokes. The
common mode chokes are incorporated for added EMI suppression and are
often necessary for FCC and CISPR 22 Class B certification.
The Pulse PE-68051 also provides transmit and receive transformers,
transmit chokes and includes a low pass filter on each transmit path. This
added transmit filtering when combined with the internal filtering of the IC
improves the attenuation for designers striving to achieve compliance with
the IEEE 802.3 standard.
In typical multiport applications, many channels are in close proximity. User
compliance with FCC/CISPR 22 Class B requirements can be achieved

by applying rigorous design guidelines to suppress noise mechanisms.
Attention to high-frequency signal paths, good PCB grounding techniques,
and component placement are critical. Refer to the suggested layout on
page 8.
All eight modules are encapsulated in a 40-pin surface mountable package.
Mechanical features include:
1. Lightweight - approximately 4 grams for rapid pick-and-place.
2. Compliant leads - provide excellent solder joint reliability.
3. Low profile - under 6 mm to accommodate industry standard pick and
4. Compact form factor - footprint allows the user to lay out four ports
Modules are packaged in tubes unless Tape & Reel is specified. Please
add the suffix “T” such as PE-68049LT for Tape & Reel packaging, in
increments of 250 pieces.
Pulse also offers a full line of 10Base-T filter modules, designed to IEEE
specifications. We provide other pin-out configurations within this package.
