Revision
Corrected Typographical Errors
Corrected Vcc and GND nomenclature and Figure 10
Made Preliminary, added PCB layouts and package mechanical diagram
Changed the capacitor values see Analog Component Values on page 22 (C2 and C3) and the pin for C3 on the diagram (page 22). Exchanged
the Tx and Rx filters on PC board layout for ATM user.
Corrected Board layouts and timing specs, added multi-PHY waveforms.
