APPLICATION NOTES
Bel has designed these part types for use in either 100 Mbps or 10/100 Mbps multi-port applications, where the PHY
device requires 1:1 transmit and receive isolation transformer ratios. Please refer to the Bel short form catalog for
recommendations of mating semiconductors. These quad, 4-port devices provide high isolation transformers, signal
wave shaping, fast but controlled rise times, EMI and common mode noise suppression. All part types meet IEEE
802.3 standards, which includes a requirement for 350μH OCL (inductance) at 8mA DC bias applied. Use of these Bel
part types provides optimum space and cost per port efficiency with no sacrifice in performance versus similar single
port devices.
The S558-5999-B2 was specifically designed for use with stacked RJ-45 connectors. The S558-5999-B2 performs
the necessary trace crossovers internal to the magnetics module, which are normally found directly on the user's PC
board. This unique crossover magnetics design approach has no performance degradation versus the straight
through approach, allows for elimination of layers and via holes on the user's PC board, and may enhance noise
suppression.
Refer to Bel's application note on the background and proper use of the impedance matched common mode
termination, which can be eliminated with use of the parts listed in this data sheet.
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.
