16K x 16K TSI, 32 I/O at 32Mbps, 3.3V

The IDT72V73260 has a non-blocking switch capacity of 16,384 x 16,384 channels at 32.768Mb/s. With 32 inputs and 32 outputs, programmable per stream control, and a variety of operating modes the IDT72V73260 is designed for the TDM time slot interchange function in either voice or data applications. Some of the main features of the IDT72V73260 are LOW power 3.3 Volt operation, automatic ST-BUS /GCI sensing, memory block programming, simple microprocessor interface , JTAG Test Access Port (TAP) and per stream programmable input offset delay, variable or constant throughput modes, output enable and processor mode. 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.
