DESCRIPTION:
The IDT72V71660 has a non-blocking switch capacity of 2,048 x 2,048
channels at 2.048Mb/s, 4,096 x 4,096 channels at 4.096Mb/s, and 8,192 x
8,192 channels at 8.192Mb/s and 16,384 x 16,384 channels at 16.384Mb/s.
With 64 inputs and 64 outputs, programmable per stream control, and a variety
of operating modes the IDT72V71660 is designed for the TDM time slot
interchange function in either voice or data applications.
Some of the main features of the IDT72V71660 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 IDT72V71660 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.
