DESCRIPTION

I These address lines access all internal memories.

Serial clock for shifting data in/out on the serial data stream. This input accepts a 32.768 MHz clock.

This active LOW input is used by a microprocessor to activate the microprocessor port of IDT72V73260.

I/O These pins are the data bits of the microprocessor port.

I This active LOW input works in conjunction with

to enable the read and write operations and sets the

data bus lines (D0-D15).

Indicates that a data bus transfer is complete. When the bus cycle ends, this pin drives HIGH and then goes

high-impedance, allowing for faster bus cycles with a weaker pull-up resistor. A pull-up resistor is required

to hold a HIGH level when the pin is in high-impedance.

This input can be used to measure delay in the data path by comparing the frame pulse, F32i, with this input.

This is the output enable control for the TX serial outputs. When the ODE input is LOW and the Output Stand

By bit of the Control Register is LOW, all TX outputs are in a high-impedance state. If this input is HIGH, the TX

output drivers are enabled. However, each channel may still be put into a high-impedance state by using the

per-channel control bits in the Connection Memory.

This input puts the IDT72V73260 into a reset state that clears the device internal counters, registers and

brings TX0-31 and D0-D15 into a high-impedance state. The

RESET

pin must be held LOW for a minimum

of 20ns to properly reset the device.

This input controls the direction of the data bus lines (D0-D15) during a microprocessor access.

Serial data input stream. These streams have a data rate of 32.768Mb/s.

Provides the clock to the JTAG test logic.

JTAG serial test instructions and data are shifted in on this pin. This pin is pulled HIGH by an internal pull-up

when not driven.

JTAG serial data is output on this pin on the falling edge of TCK. This pin is held in high-impedance state

when JTAG scan is not enabled.

JTAG signal that controls the state transitions of the TAP controller. This pin is pulled HIGH by an internal

pull-up when not driven.

Asynchronously initializes the JTAG TAP controller by putting it in the Test-Logic-Reset state. This pin is

pulled by an internal pull-up when not driven. This pin should be pulsed LOW on power-up, or held LOW,

to ensure that the IDT72V73260 is in the normal functional mode.

Serial data output stream. These streams have a data rate of 32.768Mb/s.

When all 32 output streams are selected via Control Register, these pins are the output streams TX16 to TX31

and operate at 32.768Mb/s. When output enable function is selected, these pins reflect the active or

high-impedance status for the corresponding output stream Output Enable Indication0-15.

IDT72V73260 3.3V TIME SLOT INTERCHANGE

DIGITAL SWITCH 16,384 x 16,384

INDUSTRIAL TEMPERATURE RANGE

DESCRIPTION (CONTINUED)

The IDT72V73260 is capable of switching up to 16,384 x 16,384 channels

without blocking. Designed to switch 64 Kbit/s PCM or N x 64 Kbit/s data, the

device maintains frame integrity in data applications and minimizes throughput

delay for voice applications on a per-channel basis.

The 32 serial input streams (RX) of the IDT72V73260 are run at 32.768Mb/s

allowing 512 channels per 125µs frame. The data rates on the output streams

(TX) are identical to those on the input streams (RX).

With two main operating modes, Processor Mode and Connection Mode, the

IDT72V73260 can easily switch data from incoming serial streams (Data

Memory) or from the controlling microprocessor via Connection Memory. As

control and status information is critical in data transmission, the Processor Mode

is especially useful when there are multiple devices sharing the input and output

streams.

With data coming from multiple sources and through different paths, data

entering the device is often delayed. To handle this problem, the IDT72V73260

has a Frame Evaluation feature to allow individual streams to be offset from the

frame pulse in half clock-cycle intervals up to +7.5 clock cycles.

The IDT72V73260 also provides a JTAG test access port, memory block

programming, a simple microprocessor interface and automatic ST-BUS

/GCI

sensing to shorten setup time, aid in debugging and ease use of the device

without sacrificing capabilities.

SERIAL DATA INTERFACE TIMING

For a 32.768Mb/s serial data rate , the master clock frequency will be running

at 32.768 MHz resulting in a single-bit per clock. The IDT72V73260 provides

two different interface timing modes, ST-BUS

or GCI.

The IDT72V73260 automatically detects the presence of an input frame

pulse and identifies it as either ST-BUS

or GCI. In ST-BUS

Mode, data is

clocked out on the falling edge and is clocked in on the subsequent rising-edge.

See Figure 14 for timing. In GCI Mode, data is clocked out on the rising edge

and is clocked in on the subsequent falling edge. See Figure 15 for timing.

INPUT FRAME OFFSET SELECTION

Input frame offset selection allows the channel alignment of individual input

streams to be offset with respect to the output stream channel alignment. Although

all input data comes in at the same speed, delays can be caused by variable

path serial backplanes and variable path lengths which may be implemented

in large centralized and distributed switching systems. Because data is often

delayed, this feature is useful in compensating for the skew between input

streams.

Each input stream can have its own delay offset value by programming the

frame input offset registers (FOR, Table 8). The maximum allowable skew is +7.5

master clock (C32i) periods forward with a resolution of ½ clock period, see

Table 9. The output frame cannot be adjusted.

SERIAL INPUT FRAME ALIGNMENT EVALUATION

The IDT72V73260 provides the Frame Evaluation input to determine

different data input delays with respect to the frame pulse F32i. A measurement

cycle is started by setting the Start Frame Evaluation bit of the Control Register

LOW for at least one frame. When the Start Frame Evaluation bit in the Control

the Complete Frame Evaluation bit of the Frame Alignment Register changes

from LOW to HIGH to signal that a valid offset measurement is ready to be read

from bits 0 to 12 of the Frame Alignment Register . The Start Frame Evaluation

bit must be set to zero before a new measurement cycle is started.

In ST-BUS

mode, the falling edge of the frame measurement signal (Frame

Evaluation) is evaluated against the falling edge of the ST-BUS

frame pulse.

In GCI mode, the rising edge of Frame Evaluation is evaluated against the rising

edge of the GCI frame pulse. See Table 7 and Figure 1 for the description of

the Frame Alignment Register.

MEMORY BLOCK PROGRAMMING

The IDT72V73260 provides users with the capability of initializing the entire

Connection Memory block in two frames. To set bits 14 and 15 of every

Connection Memory location, first program the desired pattern in the Block

Programming Data Bits (BPD 1-0), located in bits 7 and 8 of the Control Register.

The block programming mode is enabled by setting the Memory Block

Program bit of the Control Register HIGH. When the Block Programming Enable

bit of the Control Register is set to HIGH, the Block Programming data will be

loaded into the bits 14 and 15 of every Connection Memory location. The other

Connection Memory bits (bit 0 to bit 13) are loaded with zeros. When the memory

block programming is complete, the device resets the Block Programming

Enable, BPD 1-0 and Memory Block Program bits to zero.

FUNCTIONAL DESCRIPTION

DATA AND CONNECTION MEMORY

All data that comes in through the RX inputs go through a serial-to-parallel

conversion before being stored into internal Data Memory. The 8 KHz frame

pulse (F32i) is used to mark the 125µs frame boundaries and to sequentially

address the input channels in Data Memory.

Data output on the TX streams may come from either the serial input streams

(Data Memory) or from the microprocessor (Connection Memory). In the case

that RX input data is to be output, the addresses in Connection Memory are used

to specify a stream and channel of the input. The Connection Memory is setup

in such a way that each location corresponds to an output channel for each

particular stream. In that way, more than one channel can output the same data.

In Processor Mode, the microprocessor writes data to the Connection Memory

locations corresponding to the stream and channel that is to be output. The lower

half (8 least significant bits) of the Connection Memory is output every frame until

the microprocessor changes the data or mode of the channel. By using this

Processor Mode capability, the microprocessor can access input and output

time-slots on a per-channel basis.

The two most significant bits of the Connection Memory are used to control

per-channel mode of the out put streams. Specifically, the MOD1-0 bits are used

to select Processor Mode, Constant or Variable delay Mode, and the high-

impedance state of output drivers. If the MOD1-0 bits are set to 1-1 accordingly,

only that particular output channel (8 bits) will be in the high-impedance state.

If however, the ODE input pin is LOW and the Output Standby Bit in the Control

particular channel in Connection Memory has enabled the output for that

channel. In other words, the ODE pin and Output Stand By control bit are master

output enables for the device (See Table 3).
