FEATURES:

DESCRIPTION:

•

8K x 8K non-blocking switching at 32.768Mb/s

16 serial input and output streams

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

fortheTDMtimeslotinterchangefunctionineithervoiceordataapplications.

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.

Accepts single-bit single-data streams at 32.768Mb/s

Per-channel Variable Delay Mode for low-latency applications

Per-channel Constant Delay Mode for frame integrity applications

Automatic identification of ST-BUS^®and GCI bus interfaces

Automatic frame offset delay measurement

Per-stream single data frame delay offset programming

Per-channel high-impedance output control

Direct microprocessor access to all internal memories

Memory block programming for quick setup

IEEE-1149.1 (JTAG) Test Port

3.3V Power Supply

Available in 144-pin (20mm x 20mm) Thin Quad Flatpack (TQFP)

and 144-pin (13mm x 13mm) Plastic Ball Grid Array (PBGA)

Operating Temperature Range -40°C to +85°C

The IDT72V73250 is capable of switching up to 8,192 x 8,192 channels

withoutblocking.Designedtoswitch64Kbit/sPCMorNx64Kbit/sdata,the
