IEEE AC Transceiver Parameters
IEEE tests are typically based on templates and cannot simply be specified by number.
For an exact description of the templates and the test conditions, refer to the IEEE
specifications:
• 10BASE-T IEEE 802.3 Clause 14-2000
• 100BASE-TX ANSI X3.263-1995
• 1000BASE-T IEEE 802.3ab Clause 40 Section 40.6.1.2. Figure 40-26 shows the
template waveforms for transmitter electrical specifications.
