Data Sheet

Description

The ZL50022 is a maximum 4,096 x 4,096 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

independently programmed to operate at any of the following data rates: 2.048 Mbps, 4.096 Mbps, 8.192 Mbps or

16.384 Mbps. The ZL50022 provides up to sixteen high impedance control outputs (STOHZ0 - 15) to support the

use of external tristate drivers for the first sixteen output streams (STio0 - 15). The output streams can be

configured to operate in bi-directional mode, in which case STi0 - 31 will be ignored.

The device contains two types of internal memory - data memory and connection memory. There are four modes of

operation - Connection Mode, Message Mode, BER 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 BER mode the output channel data is replaced with

a pseudo-random bit sequence (PRBS) from one of 32 PRBS generators that generates a 2¹⁵-1 pattern. On the

input side channels can be routed to one of 32-bit error detectors. In high impedance mode the selected output

channel can be put into a high impedance state.

When the device is operating as a timing master, the internal digital PLL is in use. In this mode, an external

20.000 MHz crystal is required for the on-chip crystal oscillator. The DPLL is phase-locked to one of four input

reference signals (which can be 8 kHz, 1.544 MHz, 2.048 MHz, 4.096 MHz, 8.192 MHz, 16.384 MHz or 19.44 MHz

provided on REF0 - 3). The on-chip DPLL operates in normal, holdover or freerun mode and offers jitter

attenuation. The jitter attenuation function exceeds the Stratum 4E specification.

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.
