APPLICATION NOTES
• Refer to the Bel's short form catalog for recommended National Semiconductor chip information.
• Multiple design options offered due to different PCB layout and grounding considerations. For assistance in choosing
the optimum part, please contact Bel engineering.
• 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.
• Bel's surface mount 10Base-T network component filter modules provide the complete solution as the interface
module between the IC transceiver chip and the media side connector. Designed within each module are transmit and
receive filter networks, high voltage isolation transformers and high performance EMI suppression common mode
chokes. Each module fully meets the IEEE 802.3 standards for 10 Mbps data rates over 100 meters of media cable.
• All of these part types have been designed to provide signal performance optimization, maximum noise reduction and
minimum crosstalk interference. Careful board layout and grounding techniques are also critical to control jitter and
signal reflections.
