Application Notes
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 the transceiver chips
available. 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-68050L, PE-68065L and E5007 contain 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-68049L, PE-68062L and E5002 provide transmit and receive
isolation tansformers 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
place equipment capabilities.
4. Compact form factor - footprint allows the user to lay out four ports
within the space of two double-stacked RJ-45 connectors or a total of 12
ports to a high density 50-pin connector.
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.
For more information, please contact one of the locations listed on the back
page of this data sheet or check the Product Finder on the Pulse Web site
at http://www.pulseeng.com.
