DESCRIPTION
The IQX family of SRAM-based bit-oriented switching devices is
manufactured using a 0.6µ m CMOS process. These devices
offer clock speeds of up to 133 MHz and pin-to-pin delay as low
as 7.5 ns.
The IQX devices are used in applications requiring dynamic
switching and flexible routing / interconnection of signals. These
applications include communication switches, network systems,
DSP / image processing engines and file/video servers.
At the heart of IQX devices is a non-blocking Switch Matrix. A
line in the Switch Matrix can be connected to one or more other
lines. The Switch Matrix lines are connected to I/O Ports with
programmable functional attributes.
The RapidConfigure parallel interface allows connections in the
Switch Matrix to be changed quickly and incrementally. This
interface can also be used to configure I/O Port attributes
individually and incrementally. In either case, data integrity is
maintained on all unchanged signal paths through the device.
The IQX devices support the industry standard JTAG (IEEE
1149.1) interface for boundary scan testing. The same interface
can also used for serially downloading the configuration bit
stream into the devices.
