The serial streams operate continuously at 2.048 Mb/s and are arranged in 125µs wide frames each containing 32, 8-bit channels. Four input (RX0-3) and four output (TX0-3) serial streams are provided in the IDT72V8981 device allowing a complete 128 x 128 channel non-blocking switch matrix to be constructed. The serial interface clock (C4i) for the device is 4.096 MHz. The received serial data is internally converted to a parallel format by the on chip serial-to-parallel converters and stored sequentially in a 128-position Data Memory. By using an internal counter that is reset by the input 8 KHz frame pulse, F0i, the incoming serial data streams can be framed and sequentially addressed. Data to be output on the serial streams may come from two sources: Data Memory or Connection Memory. The Connection Memory is 16 bits wide and DESCRIPTION: The IDT72V8981 is a ST-BUS® compatible digital switch controlled by a microprocessor. The IDT72V8981 can handle as many as 128, 64 Kbit/s input and output channels. Those 128 channels are divided into 4 serial inputs and FUNCTIONAL BLOCK DIAGRAM C4i F0i VCC ODE GND Timing Unit Output MUX RX0 RX1 RX2 TX0 Receive Serial Data Streams Transmit Serial Data Streams Data Memory RX3 Control Register Connection Memory TX1 TX2 TX3 Microprocessor Interface 5702 drw01 DS CS R/W A0/ DTA D0/ A5 D7 IDT and the IDT logo are registered trademarks of Integrated Device Technology, Inc.

This active LOW output indicates that a data bus transfer is complete. A pull-up resistor is required at this output. Serial data input streams. These streams have 32 channels at data rates of 2.048 Mb/s. This input identifies frame synchronization signals formatted to ST-BUS® specifications. 4.096 MHz serial clock for shifting data in and out of the data streams. These lines provide the address to IDT72V8981 internal registers. This is the input for the active HIGH data strobe on the microprocessor interface. This input operates with CS to enable the internal read and write generation. This input controls the direction of the data bus lines (D0-D7) during a microprocessor access. Active LOW input enabling a microprocessor read or write of control register or internal memories. These pins provide microprocessor access to data in the internal control register. Connection Memory HIGH, Connection Memory LOW and data memory. Serial data output streams. These streams are composed of 32, 64 Kbit/s channels at data rates of 2.048 Mb/s. This is an output enable for the TX0-3 serial outputs. If this input is LOW, TX0-3 are high-impedance. If this is HIGH, each channel may still be put into high-impedance by software control. 3 IDT72V8981 3.3V Time Slot Interchange Digital Switch 128 x 128 Commercial Temperature Range As information enters the IDT72V8981 it must first pass through an internal serial-to-parallel converter. Likewise, before data leaves the device, it must pass through the internal parallel-to-serial converter. This data preparation has an effect on the channel positioning in the frame immediately following the incoming frame—mainly, data cannot leave in the same time slot. Therefore, information that is to be output in the same channel position as the information is input, relative to the frame pulse, will be output in the following frame. Whether information can be output during a following timeslot after the information entered the IDT72V8981 depends on which RX stream the channel information enters on and which TX stream the information leaves on. This is caused by the order in which input stream information is placed into Data Memory and the order in which stream information is queued for output. Table 1 shows the allowable input/output stream combinations for the minimum two channel delay. FUNCTIONAL DESCRIPTION (Cont'd) is split into two 8-bit blocks—Connection Memory HIGH and Connection Memory LOW. Each location in Connection Memory is associated with a particular channel in an output stream so as to provide a one-to-one correspondence between Connection and Data Memories. This correspondence allows for per channel control for each TX output stream. In Processor Mode, data output on the TX is taken from the Connection Memory Low and originates from the microprocessor (Figure 2). Where as in Connection Mode (Figure 1), data is read from Data Memory using the address in Connection Memory. Data destined for a particular channel on the serial output stream is read during the previous channel time slot to allow time for memory access and internal parallel-to-serial conversion. CONNECTION MODE In Connection Mode, the addresses of input source for all output channels are stored in the Connection Memory Low. The Connection Memory Low locations are mapped to corresponding 8-bit x 32-channel output. The contents of the Data Memory at the selected address are then transferred to the parallelto-serial converters. By having the output channel to specify the input channel through the Connection Memory, input channels can be broadcast to several output channels. SOFTWARE CONTROL If the A5 address line input is LOW then the IDT72V8981 Internal Control Register is addressed. If A5 input line is high, then the remaining address input lines are used to select the 32 possible channels per input or output stream. The address input lines and the Stream Address bits (STA) of the Control register give the user the capability of selecting all positions of IDT72V8981 Data and Connection memories. The IDT72V8981 memory mapping is illustrated in Table 2 and Figure 3. The data in the control register (Table 3) consists of Memory Select and Stream Address bits, Split Memory and Processor Mode bits. In Split Memory mode (Bit 7 of the Control register) reads are from the Data Memory and writes are to the Connection Memory as specified by the Memory Select Bits (Bits 4 and 3 of the Control Register). The Memory Select bits allow the Connection Memory HIGH or LOW or the Data Memory to be chosen, and the Stream Address bits define internal memory subsections corresponding to input or output streams. The Processor Enable bit (bit 6) places EVERY output channel on every output stream in Processor mode; i.e., the contents of the Connection Memory LOW (CML, see Table 5) are output on the TX output streams once every frame unless the ODE input pin is LOW. If PE bit is HIGH, then the IDT72V8981 behaves as if bits 2 (Channel Source) and 0 (Output Enable) of every Connection Memory High (CMH) locations were set to HIGH, regardless of the actual value. If PE is LOW, then bit 2 and 0 of each Connection Memory High location operates normally. In this case, if bit 2 of the CMH is HIGH, the associated TX output channel is in Processor Mode. If bit 2 of the CMH is LOW, then the contents of the CML define the source information (stream and channel) of the time slot that is to be switched to an output. If the ODE input pin is LOW, then all the serial outputs are high-impedance. If ODE is HIGH, then bit 0 (Output Enable) of the CMH location enables (if HIGH) or disables (if LOW) the output stream and channel. PROCESSOR MODE In Processor Mode the CPU writes data to specific Connection Memory Low locations which are to be output on the TX streams. The contents of the Connection Memory Low are transferred to the parallel-to-serial converter one channel before it is to be output and are transmitted each frame to the output until it is changed by the CPU. CONTROL The Connection Memory High bits (Table 4) control the per-channel functions available in the IDT72V8981. Output channels are selected into specific modes such as: Processor mode or Connection mode and Output Drivers Enabled or in three-state condition. OUTPUT DRIVE ENABLE (ODE) The ODE pin is the master three-state output control pin. If the ODE input is held LOW all TX outputs will be placed in high impedance regardless Connection Memory High programming. However, if ODE is HIGH, the contents of Connection Memory High control the output state on a per-channel basis. DELAY THROUGH THE IDT72V8981 The transfer of information from the input serial streams to the output serial streams results in a delay through the device. The delay through the IDT72V8981 device varies according to the combination of input and output streams and the movement within the stream from channel to channel. Data received on an input stream must first be stored in Data Memory before it is sent out.

Connection Mode Figure 2. Processor Mode 4 IDT72V8981 3.3V Time Slot Interchange Digital Switch 128 x 128 Commercial Temperature Range During the microprocessor initialization routine, the microprocessor should program the desired active paths through the matrices, and put all other channels into the high impedance state. Care should be taken that no two connected TX outputs drive the bus simultaneously. With the CMH setup, the microprocessor controlling the matrices can bring the ODE signal high to relinquish high impedance state control to the Connection Memory High bits outputs. INITIALIZATION OF THE IDT72V8981 On initialization or power up, the contents of the Connection Memory High can be in any state. This is a potentially hazardous condition when multiple TX outputs are tied together to form matrices. The ODE pin should be held low on power up to keep all outputs in the high impedance condition until the contents of the CMH are programmed.
