Figure 17. ispXPGA PLL_RST and PLL_FBK Generation
Clock Routing
The Global Clock Lines (GCLK) have two sources, their dedicated pins and the sysCLOCK circuit. Figure 18 illus-
trates the generation of the Global Clock Lines.

sysIO Capability
All the ispXPGA devices have eight sysIO banks, where each bank is capable of supporting multiple I/O standards.
Each sysIO bank has its own I/O supply voltage (VCCO) and reference voltage (VREF) resources allowing each
bank complete independence from the others. Each I/O is individually configurable based on the bank’s VCCO and
VREF settings. In addition, each I/O has configurable drive strength, weak pull-up, weak pull-down, or a bus-keeper
latch. Table 4 lists the number of I/Os supported per bank in each of the ispXPGA devices. In addition, 5V tolerant
inputs are specified within an I/O bank that is connected to VCCO of 3.0V to 3.6V for LVCMOS 3.3, LVTTL and PCI
interfaces.
Table 5 lists the sysIO standards with the typical values for VCCO, VREF and VTT.
The TOE, JTAG TAP pins, PROGRAM, CFG0 and DONE pins of the ispXPGA device are the only pins that do not
have the sysIO capabilities. The TOE and CFG0 pins operate off the VCC of the device, supporting only the LVC-
MOS standard corresponding to the device supply voltage. The TAP pins have a separate supply voltage (VCCJ),
which determines the LVCMOS standard corresponding to that supply voltage.
There are three classes of I/O interface standards that are implemented in the ispXPGA devices. The first is the un-
terminated, single-ended interface. It includes the 3.3V LVTTL standard along with the 1.8V, 2.5V, and 3.3V LVC-
MOS interface standards. Additionally, PCI and AGP-1X are subsets of this type of interface.
