Detailed Description
Input/Output Blocks (IOBs)
Virtex-II I/O blocks (IOBs) are provided in groups of two or
four on the perimeter of each device. Each IOB can be used
as an input and/or an output for single-ended I/Os. Two
IOBs can be used as a differential pair. A differential pair is
always connected to the same switch matrix, as shown in
Figure
IOB blocks are designed for high-performance I/Os, sup-
porting 19 single-ended standards, as well as differential
signaling with LVDS, LDT, Bus LVDS, and LVPECL.
Note: Differential I/Os must use the same clock.
Supported I/O Standards
Virtex-II IOB blocks feature SelectI/O-Ultra inputs and out-
puts that support a wide variety of I/O signaling standards.
In addition to the internal supply voltage (V
