TIME SLOT INTERCHANGE IDT7290820 DIGITAL SWITCH 2,048 x 2,048 (PQFP) and 100-pin Thin Quad Flatpack (TQFP) Operating Temperature Range -40C to +85C 2,048 x 2,048 channel non-blocking switching at 8.192 Mb/s 5V Power Supply 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 The IDT7290820 is a non-blocking digital switch that has a capacity of Per-stream frame delay offset programming 2,048 x 2,048 channels at a serial bit rate of 8.192 Mb/s, 1,024 x 1,024 channels Per-channel high impedance output control at 4.096 Mb/s and 512 x 512 channels at 2.048 Mb/s. Some of the main features Per-channel Processor Mode are: programmable stream and channel control, Processor Mode, input offset Control interface compatible to Intel/Motorola CPUs delay and high-impedance output control. Connection memory block programming Per-stream input delay control is provided for managing large multi-chip IEEE-1149.1 (JTAG) Test Port switches that transport both voice channel and concatenated data channels. In Available in 84-pin Plastic Leaded Chip Carrier (PLCC), addition, input streams can be individually calibrated for input frame offset. 100-pin Ball Grid Array (BGA), 100-pin Plastic Quad Flatpack VCC GND RESET TMS TDI TDO TCK TRST IC ODE Test Port RX0 TX0 RX1 TX1 RX2 Loopback TX2 RX3 TX3 RX4 TX4 Receive RX5 Transmit TX5 Output Serial Data RX6 Serial Data TX6 MUX Streams RX7 Data Memory Streams TX7 RX8 TX8 RX9 TX9 RX10 TX10 RX11 TX11 Connection RX12 TX12 Internal Memory RX13 TX13 Registers RX14 TX14 RX15 TX15 Timing Unit Microprocessor Interface F0i DS/ DTA CLK FE/ WFPS AS/ IM CS R/W/ A0-A7 CCO D8-D15/ RD WR HCLK ALE AD0-AD7 5713 drw01 The IDT logo is a registered trademark of Integrated Device Technology, Inc. 1 2001 Integrated Device Technology, Inc.
