AVDD_RX
PWR
C1, D2, G2, H1
Analog 1.8V Receiver Power Supply
AVDD_RX should be isolated from the digital power supplies. For
best results, use a ferrite bead along with an internal power plane
separation. The AVDD_RX power supply pins should have
bypass capacitors to the nearest ground.
AVDD_TX
PWR
C14, D13, G13, H14
Analog 1.8V Transmitter Power Supply
AVDD_TX should be isolated from the digital power supplies. For
best results, use a ferrite bead along with an internal power plane
separation. The AVDD_TX power supply pins should have
bypass capacitors to the nearest ground.
VDD_CML
PWR
A4, A7, A10, A12, B3, B5,
B7, B9, C11, C13
CML 1.8V Power Supply
These pins require a 1.8V potential.
VDD_CMOS
PWR
E6, E8, F3, F5, F7, F9, J4,
J7, M6, M9, M12
Digital 1.8V Power Supply
VDD_CMOS should be isolated from the analog power supplies.
For best results, use a ferrite bead along with an internal power
plane separation. The VDD_CMOS power supply pins should
have bypass capacitors to the nearest ground.

3.3V LVPECL/ 3.3V LVDS Input /Output Bus Power Supply
and 3.3V Digital I/O Power Supply
These pins require a 3.3V potential in LVPECL or LVDS opera-
tion. These pins also power the 3.3V Digital I/O Power Supply.
