IDT72V90823

3.3 VOLT TIME SLOT INTERCHANGE DIGITAL SWITCH 2,048 x 2,048 IDT72V90823 FEATURES: 2,048 x 2,048 channel non-blocking switching at 8.192 Mb/s Per-channel variable or constant throughput delay Automatic identification of ST-BUS®/GCI interfaces Accept streams of 2.048 Mb/s, 4.096 Mb/s or 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 IEEE-1149.1 (JTAG) Test Port Available in 84-pin Plastic Leaded Chip Carrier (PLCC), 100-pin Ball Grid Array (BGA), 100-pin Plastic Quad Flatpack (PQFP) and 100-pin Thin Quad Flatpack (TQFP) 3.3V Power Supply Operating Temperature Range -40°C to +85°C DESCRIPTION: The IDT72V90823 is a non-blocking digital switch that has a capacity of 2,048 x 2,048 channels at a serial bit rate of 8.192 Mb/s, 1,024 x 1,024 channels at 4.096 Mb/s and 512 x 512 channels at 2.048 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. FUNCTIONAL BLOCK DIAGRAM VCC GND RESET TMS TDI TDO TCK TRST IC ODE RX0 RX1 RX2 RX3 R...
