General 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 are individually configurable. The I/O buffers can be connected to each other through the switch matrix, which supports One-to-One and One-to-Many connections.

Features
