The DS1023 is an 8-bit programmable delay line with step sizes of 0.25ns, 0.5ns, 1ns, 2ns, and 5ns. It can be configured as a delay line, pulse width modulator, or free-running oscillator. It can delay clocks by a full period or more and guarantees monotonicity. It supports parallel or serial programming, operates on a single 5V supply, and is available in a 16-pin DIP or SOIC package.
The DS1023 provides a programmable delay line that can be configured as a delay line, pulse‑width modulator, or free‑running oscillator. It supports both parallel and serial programming modes and can cascade multiple devices for extended timing chains. The device includes an on‑chip reference delay to compensate step‑zero delay and enable full 0‑360° clock‑phase adjustment.
Technical data include step sizes from 0.25 ns to 5 ns, maximum delays up to 1275 ns, and operation from a single 5 V supply. Electrical characteristics cover supply voltage, input/output voltage levels, and absolute maximum ratings such as 50 mA short‑circuit output current.
| Supply Voltage | 5 V ±0.1 V |

| Short‑Circuit Output Current | 50 mA |
The DS1023 can be programmed in parallel or serial mode; the programming method is identical to that of the DS1020/DS1021.
The on‑chip reference delay compensates the inherent step‑zero delay, allowing accurate timing and full 0‑360° phase control.
