DM9081 Chip External Components
Figure 5 shows a typical twisted pair port external
components schematic diagram. The resistor used should
have a 1% tolerance to ensure compliance with 10BASE-T
networks. The filters and pulse transformers are necessary
devices that have a major impact on the performance and
compliance of the 10BASE-T repeater ports. Specifically,
the transmitted waveforms are heavily influenced by the
filter characteristics, and the twisted pair receivers employ
several criteria to continuously monitor the incoming
signals' amplitude and timing characteristics to determine
the necessity and the time to assert the internal carrier
sense. For these reasons, it is crucial that the values of the
resistors and the tolerances of the external components
comply with given specifications. Several manufacturers
produce modules that combine the functions of the
transmit filters, receive filters, and pulse transformers into
one package.
