Understanding Programmable Delay Lines: Overview DS1020, DS1021, DS1023, DS1045 www.maxim-ic.com
system timing control family includes programmable delay lines. These devices offer user ability program required delay after installation application rather than factory-trimmed fixed-delay intervals. Economic considerations usually dictate that this approach used whenever dynamic delay adjustment needed system, rather than convenience avoid specifying particular fixeddelay values.
DS1020/1/3 8-BIT PROGRAMMABLE SILICON DELAY LINES
These devices used many same configurations illustrated here when dynamic alteration system parameters needed. DS1020, DS1021, DS1023 offer both parallel serial methods programming. parallel mode, eight-bit word applied directly multiplexer, which selects delay time desired. These values also three-wire serial bus. DS1020 single 8-bit programmable delay line with choice serial parallel programming. Step sizes 0.15ns, 0.25ns, 0.5ns, 1ns, available. DS1021 similar, lower-cost, device. offered only packaging, with step sizes 0.25ns 0.5ns only. DS1023 more fullyfeatured device than DS1020 DS1021. inherent step zero delay time 16.5 with steps sizes 0.25ns 0.5ns ,1ns, 2ns, 5ns. addition standard features, includes step-one reference delay output, pulse-width modulator output option, inverted output option. constructed using different topology that allows delay times greater than pulse width.

DS1045 4-BIT DUAL PROGRAMMABLE DELAY LINE
DS1045 effectively 4-bit programmable delay line with simultaneous programmable outputs from single input. This device particularly useful skew adjustments allows either output lead other.
Internally, equivalent 16-tap delay line with multiplexers selecting which taps routed outputs. Each multiplexer 4-bit parallel input select required tap, byte data could fully program device. addition data sheet, there additional characterization this device Application Note Device Characteristics DS1045 Dual 4-Bit Programmable Delay Line. Futher information ease your selection, including application notes data sheets, found DS1020: DS1021 DS1023 DS1045
