The Bel parts listed on this data sheet provide a very cost efficient interface, in addition to improving performance, reducing PCB layers and minimizing board space. These Bel parts will require minimal or no trace crossovers which should reduce PCB layers and allow for straight and short line traces from the transceiver and to the connectors. • S558-5999-47 is a quad, 4-port device optimized to provide a straight line connection with stackable RJ-45 connectors. • S558-5999-A3 and A5 are quad, 4-port devices optimized to provide a straight line connection with single in-line connectors. • S558-5999-A7 is a quad, 4-port device optimized to provide a straight line connection with reversed pinout stackable RJ-45 connectors. • S558-5999-A4 and A6 are dual, 2-port devices optimized for use with single in-line connectors and also includes an impedance matched common mode termination. • S558-5999-A8 and A9 are dual, 2-port devices optimized for use with single in-line connectors. • 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.
