Application Notes
Each module in this application contains low pass filers,
isolation transformers, and common mode chokes. These
components provide impedance matching, equipment
isolation, and EMI suppression to comply with IEEE 802.3
requirements. The E2001QNL, E2003QNL, E2007QNL,
PE-68025QNL and PE-68027QNL also provide the
necessary data and pre-emphasis resistors recommended
by most transceiver manufacturers.
User compliance with FCC/CSPR Class B requirements can
be achieved by applying rigorous design guidelines to
suppress noise mechanisms. Attention to high frequency
signal paths, proper PCB grounding techniques, and
component placement are critical. Pins 5 and 12, when
grounded, provide noise return paths. For PE-68025QNL,
PE-68026NL,
pins (typically pin 12) must be decoupled with a
bypass capacitor. The E2001QNL, E2003QNL, E2007QNL,
E2009QNL, and PE-68056NL do not require the bypass
capacitor, and pins 5 and 12 may be connected directly to
ground.
Recommended module orientation with respect to the
RJ-45 connector is illustrated in each application circuit.
Output pins 6 through 11 should be routed with short,
matched traces to the connector for optimum EMI
performance.
Surface mount devices manufactured by Pulse are designed
to meet all published specifications after exposure to
surface mount soldering temperatures. The products in this
data sheet are transfer molded or open header in IC-style
packaging, making them robust enough to withstand
convection and infrared reflow solder temperatures up to
245°C. In addition, compliant leads provide excellent solder-
joint reliability with a coplanarity of ±.002” (0,05mm).
For Tape and Reel orders, please add the suffix "T" to the
end of the part number (i.e.PE-68025QNLT).
