** VCCIO driven from end user carrier card 

 

Figure 7 

– Power Supply Sequencing 

 
As noted above, if connected to an end user carrier 

card, the 1.8V power supply’s power good 

output should is used as the enable to the VCCIO regulators via the PG_1V8 (VCCIO_EN) signal 
on the Micro Headers.   
 
The following diagram illustrates sequencing with an expansion card:
