What the DS1100Z-100+ does in a timing chain
The DS1100Z-100+ is a nonprogrammable silicon delay line. It takes a single digital input and produces five equally spaced output taps, each delayed by 20 ns from the previous, for a total delay of 100 ns through the last tap.
20 ns tap spacing — what it buys the board
With a 20 ns tap increment and a total delay of 100 ns, the DS1100Z-100+ covers a timing window wide enough to compensate for propagation delays across a few gates or a short PCB trace. The 5 taps let you pick the delay that best aligns a late-arriving signal without adding a separate counter or RC network. Because the delay is silicon-based — no external capacitor or resistor — the timing holds over temperature and supply variation better than a passive RC delay.
Package and mounting for the BOM
The DS1100Z-100+ comes in an 8-SOIC package (0.154" body width, 3.90 mm) with a surface-mount footprint that matches standard SOIC-8 land patterns. It ships in Tube form. The small footprint keeps board space tight, and the surface-mount package is compatible with reflow soldering processes used in volume assembly.
