• Description: In-system Programmable 3.3v Generic Digital Crosspoint
• Manufacturer: Lattice Semiconductor Corp.

ispGDX240VA timings are specified with a GRP load
(fanout) of four I/O cells. The figure below shows the ∆
GRP Delay with increased GRP loads. These deltas

OE, CLK/CLKEN, MUXsel0-1). Global Clock signals
which do not use the GRP have no fanout delay adder.
