NOTE: Part numbers indicated with an asterisk (*) are enhanced performance parts. All transmit turns ratios are 1:1, except the E2009 which is
1: 1.414. For the PE-680XXNL part series, the receive and transmit sides meet IEEE 802.3i 1993 specifications, while transmit side is enhanced for
FCC/VDE Class B system emissions requirement. Specifications reflect filter sections. Additional attenuation is due to predistortion resistors.

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, and PE-68027QNL, one of these 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 & Reel orders, please add the suffix “T” to the end of the
part number (i.e.PE-68025QNLT).
