DESCRIPTION

E4

**** Transmit Analog Power Supply (3.3V ±5%)

F4

TVDD can be shared with DVDD. However, it is recommended that TVDD be

F16

isolated from the analog power supply RVDD. For best results, use an internal

E17

power plane for isolation. If an internal power plane is not available, a ferrite

R4

bead can be used. Each power supply pin should be bypassed to ground

through an external 0.1µF capacitor.

P1

N15

P15

C2

**** Receive Analog Power Supply (3.3V ±5%)

E5

RVDD should not be shared with other power supplies. It is recommended that

G16

RVDD be isolated from the digital power supply DVDD and the analog power

D16

supply TVDD. For best results, use an internal power plane for isolation. If an

V2

internal power plane is not available, a ferrite bead can be used. Each power

supply pin should be bypassed to ground through an external 0.1µF capacitor.

U18

D2

**** Receiver Analog Ground

G3

It’s recommended that all ground pins of this device be tied together.

M2

M17

R17

K17 **** Analog Power Supply (1.8V ±5%)

J3

AVDD should be isolated from the digital power supplies. For best results, use

J2

an internal power plane for isolation. If an internal power plane is not available,

a ferrite bead can be used. Each power supply pin should be bypassed to

ground through at least one 0.1µF capacitor.

J17 **** Analog Ground

K3

It’s recommended that all ground pins of this device be tied together.

L4

A18 **** Digital Power Supply (3.3V ±5%)

R9

DVDD should be isolated from the analog power supplies. For best results, use

D9

an internal power plane for isolation. If an internal power plane is not available,

K15

a ferrite bead can be used. Every two DVDD power supply pins should be

bypassed to ground through at least one 0.1µF capacitor.

J4

V1

**** Digital Power Supply (1.8V ±5%)

U10

DVDD should be isolated from the analog power supplies. For best results, use

K18

an internal power plane for isolation. If an internal power plane is not available,

D10

a ferrite bead can be used. Every two DVDD power supply pins should be

A9

bypassed to ground through at least one 0.1µF capacitor.

NOTE: For proper operation, the power-up sequence is: bring up 1.8V power

befor the 3.3V.
