IEEE tests are typically based on template and cannot simply be specified by a number. For an exact description of the template and the test
conditions, refer to the IEEE specifications.
(Over full range of values listed in the Recommended Operating Conditions unless otherwise specified)
• 10BASE-T IEEE 802.3 Clause 14
• 100BASE-TX ANSI X3.263-1995

1. IEEE 802.3 Clause 14-2000, Figure 14.9 shows the template for the “far end” wave form. This template allows as little as 495 mV
2. The input test is actually a template test, IEEE 802.3 Clause 14-2000. Figure 14.17 shows the template for the receive wave form.
3. The ANSI TP-PMD specification requires that any received signal with peak-to-peak differential amplitude greater than 1000 mV
4. The ANSI TP-PMD specification requires that any received signal with peak-to-peak differential amplitude less than 200 mV
peak differential voltage at the far end receiver.
should turn on signal detect (internal signal in 100BASE-TX mode). The will accept signals typically with 460 mV peak-to-peak
differential amplitude.
should be de-assert signal detect (internal signal in 100BASE-TX mode). The will reject signals typically with peak-to-peak dif-
ferential amplitude less than 360 mV.
