Description
The ZL50017 is a maximum 1024 x 1024 channel non-blocking digital Time Division Multiplex (TDM) switch. It has
sixteen input streams (STi0 - 15) and sixteen output streams (STio0 - 15). The device can switch 64 kbps and
Nx64 kbps TDM channels from any input stream to any output stream. All of the input and output streams operate
at the same data rate and can be programmed at any of the following data rates: 2.048 Mbps, 4.096 Mbps,
8.192 Mbps or 16.384 Mbps. The output streams can be configured to operate in bi-directional mode, in which case
STi0 - 15 will be ignored.
The device contains two types of internal memory - data memory and connection memory. There are three modes
of operation - Connection Mode, Message Mode and high impedance mode. In Connection Mode, the contents of
the connection memory define, for each output stream and channel, the source stream and channel (the actual
data to be output is stored in the data memory). In Message Mode, the connection memory is used for the storage
of microprocessor data. Using Zarlink's Message Mode capability, microprocessor data can be broadcast to the
data output streams on a per-channel basis. This feature is useful for transferring control and status information for
external circuits or other TDM devices. In high impedance mode the selected output channel can be put into a high
impedance state.
The configurable non-multiplexed microprocessor port allows users to program various device operating modes
and switching configurations. Users can employ the microprocessor port to perform register read/write, connection
memory read/write and data memory read operations. The port is configurable to interface with either Motorola or
Intel-type microprocessors.
The device also supports the mandatory requirements of the IEEE-1149.1 (JTAG) standard via the test port.
