APPLICATION CIRCUIT

APPLICATION NOTES

• Bel has developed a variety of quad, 4-port part types for use with Level One and Texas Instrument quad, 4-port PHY

devices 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 4 channels of

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.

• These parts have been optimized for PC board layouts utilizing stackable or "double decker" RJ-45 connectors, in

order to keep board traces short and straight.
