GENERAL DESCRIPTION

The VSC9195 is a 136 x 136 Time Slot Interchange (TSI) Switch IC supporting TFI-5 (STS-48 like frame) data on every input and output. All inputs and outputs are differential serial signals running at 2.488 Gb/s for TDM signals, or 2.125 Gb/s, or 2.488-2.67 Gb/s for signals to be routed transparently.
