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

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

µsframe.Thedataratesontheoutputstreams

(TX) are identical to those on the input streams (RX).
