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
components provide impedance matching,
equipment isolation, and EMI compression to
comply with IEEE requirements. 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 is critical. Pins 5 and 12,
when grounded, provide noise return paths. At
least one of these (typically pin 12) must be
coupled with bypass capacitor. Recommended
module orientation with respect to RJ45
connector is illustrated in the application circuit.
Output pins 6 through 11 should be routed with
short, matched traces to the connector for
optimum EMI performance. The robust
mechanical package withstands IR reflow
temperatures up to 235C. Compliant leads
provide excellent solder-joint reliability with
K.002 coplanarity. Modules are shipped in
tubes.
