APPLICATION NOTES
• Bel has developed a variety of dual, 2-port and quad, 4-port part types for use with Crystal Semiconductor's product
line of dual, 2-port and quad, 4-port PHY transceivers that incorporate digital filtering techniques within the silicon
itself. Bel's "filterless magnetics" are optimized for this specific application and create a very cost efficient design
solution. Each Bel part type contains transmit and receive transformers to provide for wave shaping, high voltage
isolation and EMI noise suppression.
• Bel has designed these parts as a family of parts with common footprint and pinouts to enable the designer to
customize the use of common mode choke for optimum system performance.
• In multi-port system applications, good PCB layout and proper grounding techniques are very critical to achieve FCC
class A and B equipment approvals. Bel recommendations are available and can be provided by contacting our
engineering department or your local sales representative.
• Bel's low profile, surface mount packaging is ideal for high speed pick and place machinery. Parts can be shipped on
tape and reel for high speed placement. Construction processes have been implemented for thermal compatibility
with high temperature IR reflow assembly processing. Post dipping of leads assist with PC board solderability. Each
part is optically inspected to meet rigid coplanarity requirements.
