Introduction
The ispGDX2™ family is Lattice’s second generation in-system programmable generic digital crosspoint switch for
high speed bus switching and interface applications.
The ispGDX2 family is available in two options. The standard device supports sysHSI capability for ultra fast serial
communications while the lower-cost “E-series” supports the same high-performance FPGA fabric without the
sysHSI Block.
This family of switches combines a flexible switching architecture with advanced sysIO interfaces including high
performance sysHSI Blocks, and sysCLOCK PLLs to meet the needs of the today’s high-speed systems. Through
a muliplexer-intensive architecture, the ispGDX2 facilitates a variety of common switching functions.
The availability of on-chip control logic further enhances the power of these devices. A high-performance solution,
the family supports bandwidth up to 38Gbps.
Every device in the family has a number of PLLs to provide the system designer with the ability to generate multiple
clocks and manage clock skews in their systems.
