2.8 Terminal Descriptions
Table 2−4 through Table 2−11 give a description of the terminals. These terminals are grouped in tables by
functionality. Each table includes the terminal name, terminal number, I/O type, and terminal description.
The following list describes the different input/output cell types that appear in the terminal description tables:
• HS DIFF IN = High speed differential input
• HS DIFF OUT = High speed differential output
• LV CMOS = 3.3-V low voltage CMOS input or output with 3.3-V clamp rail
• BIAS = Input/output terminals that generate a bias voltage to determine a driver’s operating current
• Feed through = these terminals connect directly to macros within the part and not through an input or
output cell.
• PWR = Power terminal
• GND = Ground terminal
