High impedance common mode chokes significantly minimize their effects. Pulse s interface modules provide the complete analog solution for 10Base-T multiport applications in various packages. Each module includes low pass filters, isolation transformers, and may contain common mode chokes. The 78Z034CNL contains data and pre-equalization resistors on the transmit channel; and the receive channel is terminated with impedance matching resistors. 3. Electrical Functions Include: 1. Impedance Matching - The low pass filters, in conjunction with selected resistor values, effectively match the impedance characteristics of the IC to those of the transmission line. Precision wound inductors help control passband impedances and lower return loss parameters. The proper cut-off frequency minimizes insertion loss and delay distortion while maximizing attenuation in the stopband. 2. EMI Suppression - The filter module is designed to control signal harmonics and jitter, reflections, crosstalk interferences, Equipment Isolation - The transformer is designed to withstand 2000 Vrms, ensuring protection from static charge on the twisted pair line. Each module is fully tested to ensure compliance with IEEE 802.3 1993 standards. In some applications, such as multiport repeaters, many channels are in close proximity. User compliance with FCC/CISPR22 Class B requirements can be achieved by applying rigorous design guidelines to suppress noise mechanisms. Attention to high frequency signal paths, good PCB grounding techniques, and component placements are critical. A typical Network Interface Card Application is featured below.
