20 ns total delay, 4 ns per tap — what it means for the signal chain
The Maxim Integrated DS1100U-20+ is a nonprogrammable 5-tap silicon delay line that delivers a total delay of 20 ns from input to final tap, with each of the five taps spaced at 4 ns increments.
Tap timing and supply — the specs that decide fit
The 4 ns tap increment sets the resolution of the delay steps. The 20 ns total window limits the maximum offset this single device can introduce.
Lifecycle and sourcing — active, no LTB risk
The DS1100U-20+ carries an Active lifecycle status and is ROHS3 compliant. There is no last-time-buy or end-of-life notice on record, so it remains a safe choice for new designs and production builds. No official second source or cross-reference is listed in the manufacturer data, so dual-sourcing would require a functionally equivalent part from another vendor — not a pin-compatible drop-in.
