MSX Family Data Sheet
Features
Description
The MSX family of SRAM-based bit-oriented switching devices offer flow-through NRZ data rates of up to
150Mb/s and registered clock frequencies of up to 75MHz. The I/O Buffers (IOBs) are individually configurable.
The IOBs can be connected to each other through the switch matrix, which supports One-to-One and One-to-
Many connections.
The proprietary RapidConfigure parallel interface allows fast configuration of both the IOBs and switch matrix.
It also allows readback of the device for test and verification purposes. The MSX devices also support the
industry standard JTAG (IEEE 1149.1) interface for boundary scan testing. The JTAG interface can also be used
to download configuration data to the device. A functional block diagram of the MSX architecture is shown in
