Application Notes
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 E2010 contains data and pre-equalization
resistors on the transmit channel; and the receive channel is
terminated with impedance matching resistors.
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,
and common mode noise, which may contribute to radiated
and conducted emissions. High impedance common mode
chokes significantly minimize their effects.
3. 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.
