1) Receive and transmit sides meet IEEE 802.3i-1993 specification, transmit side is enhanced for FCC/VDE class B system emissions requirement.
Specifications reflect filter sections, additional attenuation is due to pre-distortion resistors.

The module contains low pass filters , isolation
transformers, and common mode chokes. These
com ponents provide impedance m atching,
equi pment isolation, and E MI compr e ssion to
comply with IEE E requirements. User
compliance with FCC/CS PR clas s B
requirements can be achieved by applying
rigorous design guidel ines to suppress noise
mechanisms. Attention to high fr equency signal
paths, proper PCB grounding techniques, and
com ponent placem ent is critical. Pins 5 and 12,
when grounded, provide noise return paths. At

least one of these (typically pin 12) mus t be
coupled with bypas s capacitor. Recommended
module orienta tion with respect to RJ45
connector is illustr ated in th e app lic at ion cir cui t .
Output pins 6 through 11 should be routed with
short, m atche d traces to the con nec tor f or
optimum EMI perfor mance. T he robust
mechanical pack age with stands IR reflow
tem peratures up to 235°C. Com pliant leads
provide excellent solder-joint reliability with
K.002 coplanarity. Modul e s are shippe d in
tubes.
