Delay values, programmed via the serial interface, can be independently varied over 15 equal steps. The step size (in ns) is determined by the device dash number. Each input is reproduced at the corresponding output without inversion, shifted in time as per user selection. For each line, the delay time is given by: TDn = T0 + An * TI PIN DESCRIPTIONS I1-I4 O1-O4 AL SC SI SO VDD GND Signal Inputs Signal Outputs Address Latch In Serial Clock In Serial Data In Serial Data Out 3.3V Ground where T0 is the inherent delay, An is the delay address ...
