Power Sources

Power for the PES64H16 and all downstream ports is generated from the 12V from an external power connector. See Figure 2.4. A 12V to 2.5V DC-
DC converter is used to provide power to four LDO linear regulators to generate V

DD

CORE, V

DD

PEe, V

DD

APE, and V

TT

PE voltages. The 2.5V from 

the DC-DC converter is used to power the clock buffers. 3.3V is supplied form the power connector for V
