The DS1023 is an 8-bit programmable delay line similar in function to the DS1020/DS1021.Additional features have been added to extend the range of applications:The internal delay line architecture has been revised to allow clock signals to be delayed by up to a full period or more. Combined with an on-chip reference delay (to offset the inherent or "step zero" delay of the device) clock phase can now be varied over the full 0-360 degree range.On-chip gating is provided to allow the device to provide a pulse width modulated output, triggered by the input with duration set by the programmed value.Alternatively the output signal may be inverted on chip, allowing the device to perform as a free-running oscillator if the output is (externally) connected to the input.
