ESCRIPTION
VDDD3.3
PWR
A8, A13, B13, D9, D10,
D11, E11, P13, P14
Digital 3.3V Power Supply
VDDD3.3 should be isolated from the analog power supplies. For
best results, use a ferrite bead along with an internal power plane
separation. The VDDD3.3 power supply pins should have bypass
capacitors to the nearest ground.
AVDD3.3_Rx
PWR
D3, E3
Analog 3.3V Receiver Power Supply
AVDD3.3_Rx should be isolated from the digital power supplies.
For best results, use a ferrite bead along with an internal power
plane separation. The AVDD3.3_Rx power supply pins should
have bypass capacitors to the nearest ground.
AVDD3.3_Tx
PWR
J1, M2, P5, P9
Analog 3.3V Transmitter Power Supply
AVDD3.3_Tx should be isolated from the digital power supplies.
For best results, use a ferrite bead along with an internal power
plane separation. The TVDD3.3_Tx power supply pins should
have bypass capacitors to the nearest ground.
VDD1.8
PWR
B7, D12, E12, K11, L9,
L10, M9, M10, M11
Digital 1.8V Power Supply
VDDD1.8 should be isolated from the analog power supplies. For
best results, use a ferrite bead along with an internal power plane
separation. The VDDD1.8 power supply pins should have bypass
capacitors to the nearest ground.
AVDD1.8_Rx
PWR
D4, D5, D6, D8, F3, G3
Analog 1.8V Receiver Power Supply
AVDD1.8_Rx should be isolated from the digital power supplies.
For best results, use a ferrite bead along with an internal power
plane separation. The AVDD1.8_Rx power supply pins should
have bypass capacitors to the nearest ground.
AVDD1.8_Tx
PWR
J4, L6, L7, L8, M3, N9
Analog 1.8V Transmitter Power Supply
AVDD1.8_Tx should be isolated from the digital power supplies.
For best results, use a ferrite bead along with an internal power
plane separation. The AVDD1.8_Tx power supply pins should
have bypass capacitors to the nearest ground.
