DS1023S-200+

The DS1023S-200+ is an 8bit programmable timing element (delay line) in 16 pin WSOIC package. The internal delay line architecture has been revised to allow clock signals to be delayed for 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° 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 invertedon-chip, it allows the device to perform as a free-running oscillator if the output is (externally) connected to the input. The device programming is identical to the DS1020/DS1021. However, the serial clock and data pins are shared with three of the parallel input pins.
