a. IEEE 802.3ab Figure 40-19 points A&B.
b. IEEE 802.3 Clause 14, Figure 14.9 shows the template for the “far end” wave form. This template allows as little as 495mV peak differential
voltage at the far end receiver.
c. See IEEE 802.3, Clause 14, Figure 14.17 for the template for the receive wave form.
d. The ANSI TP-PMD specification requires that any received signal with peak-to-peak differential amplitude greater than 1000 mV should turn on
signal detect. The 82563EB/82564EB will accept signals typically with 460 mV peak-to-peak differential amplitude.
e. The ANSI TP-PMD specification requires that any received signal with peak-to-peak differential amplitude less than 200 mV should de-assert
signal detect. The 82563EB/82564EB will reject signals typically with 360 mV peak-to-peak differential amplitude

Kumeran (Serial) Interface
The Kumeran interface is electrically compatible with the SERDES implemented in 1000Base-BX
applications, as defined in the PICMG 3.1 Specification, Version 1.0, Chapter 5, Backplane
Physical Layers Interfaces. It also implements electrical idle as described in section 3.5.4. As part
of the electrical idle implementation, the Kumeran interface also needs to be able to detect when
the 631xESB/632xESB is in electrical idle.
Transmit
The transmit specifications are measured with the following test load.
