• Designed to enhance performance with National

Semiconductor 10/100 DSP 83840/83223 chipsets

• Split design allows CMC's to address 10 Mbps or 100

Mbps signals individually

• Split input on transmit channel provides better balance

of differential output signal and greater isolation between

10Base-T and 100Base-TX transceivers

• 2000 Vrms isolation

APPLICATION CIRCUIT

APPLICATION NOTES

• These Bel part types have been uniquely designed for either 100 Mbps or 10/100 Mbps data transmission systems

over category 5 UTP/STP cable. These Bel parts have been tested and qualified for use with the National

Semiconductor DP83223 TP-Transceiver and DP83840 10/100 Mbps PHY device. Each Bel module provides

superior EMI noise suppression, high voltage isolation, wave shaping and fast, but controlled rise times. All parts meet

IEEE 802.3 standards, which includes 350µH OCL (inductance) when 8mA of DC bias is applied.

• This Bel unique design approach allows for separation of the 10 Mbps and 100 Mbps signals, creating better signal

balance, superior noise suppression, optimization of performance for each 10 Mbps and 100 Mbps signal and ease

of magnetics design. The approach also allows for the addition of either a 10 Mbps or 100 Mbps common mode

choke, which could not be effectively implemented if the 10 Mbps and 100 Mbps shared the same signal lines.

• 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.
