I/O Power. Power supply balls for the I/O pads (3.3 V ± 5%).
Core Power. Power supply balls for the core (1.5 V ± 5%).
Ground. Common ground balls for 3.3 V and 1.5 V supplies.
Precharge. Precharge voltage to support H.110 hot insertion on TXD[31:00]. If the device is used in an
H.110 hot insertion applications, the signal should be connected to backplane early voltage; otherwise
connect this signal to ground.
PCI Buffer Voltage Select. For an H.110 application using TXD[31:00] in a 5 V signaling environment,
connect this signal to 5 V. For an H.110 application using TXD[31:00] in a 3 V signaling environment,
connect this signal to V
PLL Power. 1.5 V power supply for the internal phase-locked loop. Must include local 0.01 µF capacitor to
V
PLL Ground. Isolated ground for the internal phase-locked loop.
