DS1023-500

The DS1023 programmable delay line offers the following step sizes: - DS1023-025: 0.5 ns - DS1023-050: 1.0 ns - DS1023-100: 2.0 ns - DS1023-200: 4.0 ns - DS1023-500: 10.0 ns These step sizes provide a range of options for adjusting the delay time in the DS1023 programmable delay line.

The DS1023 can be configured as a reference output or a delayed output based on the Mode Select (MS) pin. When MS = 0, the DS1023 functions as follows: - Reference Output on Pin 9 - Delayed Output on Pin 15 .

The key features of the DS1023 programmable delay line mentioned in the document include: 1. The DS1023 has four possible output functions but only two output pins, with the functionality of the two output pins determined by the Mode Select (MS) pin. 2. The internal architecture of the DS1023 allows the output delay time to be considerably longer than the input pulse width, making it useful for applications such as clock phase control where delays up to and beyond one full clock period can be achieved. 3. The DS1023 is an 8-bit programmable delay line similar in function to the DS1020/DS1021, with additional features added to extend the range of applications. 4. The internal delay line architecture of the DS1023 has been revised to allow clock signals to be delayed by up to a full period or more, and combined with an on-chip reference delay, clock phase can now be varied over the full 0-360 degree range.
