Data Sheet

Type Description

1.2v digital power

1.8v or 2.1v analog power

AVDD can be fed with external 1.8v or 2.1v power.

If there is no external 1.8v power source, AVDD can be

connected the 2.1v power source generated by CTRL21. If an

external 1.8v power is available, AVDD can be connected to

1.8v to reduce the power consumption.

If there is no external 2.5v power source, the center tap of

transformer can be connected the 2.1v power source

generated by CTRL21. If an external 2.5v power is available,

the center tap of transformer can be connected to it,

consuming the extra power consumption.

3.3v/ 2.5v digial I/O power

VDDO is connected to 3.3v if IP1001 works in MII or GMII

mode. VDDO is connected to 2.5v if IP1001 works at RGMII

mode.

3.3v/ 2.5v analog power

AVDDH can be fed with 3.3v or 2.5v, using the same power

source of VDDO. Although VDDO and AVDDH use the same

power source, user has to place a bead between VDDO and

AVDDH to prevent the noise of AVDDH noise.

Exposed PAD (E-PAD) (Thermal PAD) is Analog and Digital

ground.
