The ispGDX architecture provides a family of fast, flexible
programmable devices to address a variety of system-
level digital signal routing and interface requirements
including:
The ispGDX Family consists of three members with 80,
120 and 160 Programmable I/Os. These devices are
available in packages ranging from the 100-pin TQFP to
the 208-pin PQFP. The devices feature fast operation,
with input-to-output signal delays (Tpd) of 5ns and clock-
to-output delays of 5ns.
The architecture of the devices consists of a series of
programmable I/O cells interconnected by a Global Rout-
