IDT72V73250

The IDT72V73250 has a non-blocking switch capacity of 8,192 x 8,192 channels at 32.768Mb/s. With 16 inputs and 16 outputs, programmable per stream control, and a variety of operating modes the IDT72V73250 is designed for the TDM time slot interchange function in either voice or data applications. Some of the main features of the IDT72V73250 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 IDT72V73250 is capable of switching up to 8,192 x 8,192 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 16 serial input streams (RX) of the IDT72V73250 are run at 32.768Mb/s allowing 512 channels per 125s frame. The data rates on the output streams (TX) are identical to those on the input streams (RX).
