82563EB/82564EB Gigabit Platform LAN Connect Networking Silicon

The differential peak and differential peak to peak voltage is defined as follows:

• VDIFFp = max (|V+ - V-|)

• VDIFFp-p = (2* VDIFFp)

In addition, the transmitter must meet the following eye diagram.

Receive

The receiver operates with less than 10

-12 Bit Error Rate (BER) when the received signal meets

valid voltage and timing specifications and is delivered from a balanced 100

Ω source.
