PEA I PCI Express Analog Power. PCI Express analog power used by the PLL and bias

generator.

I Ground.

PE PCI Express Serial Data Transmit Termination Voltage. This pin allows the driver

termination voltage to be set, enabling the system designer to control the Common

Mode Voltage and output voltage swing of the corresponding PCI Serial Data Transmit

differential pair.

Pin Characteristics

Note: Some input pads of the PES16H16 do not contain internal pull-ups or pull-downs. Unused inputs should be tied off to appropriate

levels. This is especially critical for unused control signal inputs which, if left floating, could adversely affect operation. Also, any input pin left

floating can cause a slight increase in power consumption.
