IDT72V70800

3.3 VOLT TIME SLOT INTERCHANGE DIGITAL SWITCH 512 x 512 FEATURES: IDT72V70800 512 x 512 channel non-blocking switching at 8.192 Mb/s Per-channel variable or constant throughput delay Automatic identification of ST-BUS®/GCI interfaces Accepts 4 Serial Data Streams of 8.192 Mb/s Automatic frame offset delay measurement Per-stream frame delay offset programming Per-channel high impedance output control Per-channel Processor Mode Control interface compatible to Intel/Motorola CPUs Connection memory block programming · Available in 64-pin Thin Plastic Quad Flatpack (TQFP) and 64-pin Small Thin Quad Flatpack (STQFP) 3.3V Power Supply Operating Temperature Range -40°C to +85°C 3.3V I/O with 5V Tolerant Inputs DESCRIPTION: The IDT72V70800 is a non-blocking digital switch that has a capacity of 512 x 512 channels at a serial bit rate of 8.192 Mb/s. Some of the main features are: programmable stream and channel control, Processor Mode, input offset delay and high-impedance output control. Per-stream input delay control is provided for managing large multi-chip switches that transport both voice channel and concatenated data channels. In addition, input streams can be individually calibrated for input frame offset.
