3.3 VOLT TIME SLOT INTERCHANGE DIGITAL SWITCH IDT72V70190 256 x 256 64-pin Small Thin Quad Flatpack (STQFP) FEATURES: 3.3V Power Supply 256 x 256 channel non-blocking switching at 2.048 Mb/s Operating Temperature Range -40C to +85C Per-channel variable or constant throughput delay 3.3V I/O with 5V Tolerant Inputs Automatic identification of ST-BUS /GCI interfaces Accept 8 serial data streams of 2.048 Mb/s DESCRIPTION: Automatic frame offset delay measurement Per-stream frame delay offset programming The IDT72V70190 is a non-blocking digital switch that has a capacity of Per-channel high impedance output control 256 x 256 channels at 2.048 Mb/s. Some of the main features are: program- Per-channel Processor Mode mable stream and channel control, Processor Mode, input offset delay and high- Control interface compatible to Intel/Motorola CPUs impedance output control. Connection memory block programming Per-stream input delay control is provided for managing large multi-chip Available in 64-pin Thin Plastic Quad Flatpack (TQFP) and switches that transport both voice channel and concatenated data channels. In addition, input streams can be individually calibrated for input frame offset.
