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. .UNCTIONAL BLOCK DIAGRAM VCC GND RESET TMS TDI TDO TCK TRST IC RX0 RX1 RX2 RX3 RX4 RX5 RX6 RX7 RX8 RX9 RX10 RX11 RX12 RX13 RX14 RX15 Receive Serial Data Streams Timing Unit Test Port Loopback Data...
