TYPE (1) IPD/IPU (2)

DESCRIPTION

 

(DVDD15/2)-V reference for HSTL buffer (EMAC RGMII). VREFHSTL can be

 

generated directly from DVDD15 using two 1-kΩresistors to form a resistor

 

divider circuit.

A

NOTE: If the RGMII mode of the EMAC is not used, the DVDD15, VREFHSTL,

 

RSV13, and RSV14 pins can be connected to directly ground (VSS) to save

 

power. However, connecting these pins directly to ground will prevent

 

boundary-scan from functioning on the RGMII pins of the EMAC. To preserve

 

boundary-scan functionality on the RGMII pins, see Section 7.3.4.

A

1.8-V I/O supply voltage.

 

1.8-V or 1.5-V I/O supply voltage for the RGMII function of the EMAC.

 

NOTE: If the RGMII mode of the EMAC is not used, the DVDD15, VREFHSTL,
