DESCRIPTION:
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
streamcontrol,andavarietyofoperatingmodestheIDT72V73250isdesigned
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,
simplemicroprocessorinterface, JTAGTestAccessPort(TAP)andperstream
programmableinputoffsetdelay,variableorconstantthroughputmodes,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
devicemaintainsframeintegrityindataapplicationsandminimizesthroughput
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 125
sframe.Thedataratesontheoutputstreams
(TX) are identical to those on the input streams (RX).
