ZL50019 Enhanced 2 K Digital Switch

Data Sheet The ZL50019 is a maximum 2,048 x 2,048 channel non-blocking digital Time Division Multiplex (TDM) switch. It has thirty-two input streams (STi0 - 31) and thirty-two output streams (STio0 - 31). The device can switch 64 kbps and Nx64 kbps TDM channels from any input stream to any output stream. Each of the input and output streams can be independ.
