under these conditions is not implied.DescriptionThe IDT72V71650 has a non-blocking switch capacity of 1,024 x 1,024 channels at 2.048Mb/s, 2,048 x 2,048 channels at 4.096Mb/s, and 4,096 x 4,096 channels at 8.192Mb/s and 8,192 x 8,192 channels at 16.384Mb/s. With 32 inputs and 32 outputs, programmable per stream control, and a variety of operating modes the IDT72V71650 is designed for the TDM time slot interchange function in either voice or data applications.
Some of the main features of the IDT72V71650 are low power 3.3 Volt operation, automatic ST-BUS® /GCI sensing, memory block programming, simple microprocessor interface, one cycle direct internal memory accesses, JTAG Test Access Port (TAP) and per stream programmable input offset delay, variable or constant throughput modes, output enable and processor mode.
The IDT72V71650 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.
