Analog Devices Inc./Maxim Integrated DS1100Z-125

Overview

DS1100Z-125 from Maxim Integrated is a 5-tap silicon delay line IC delivering precisely spaced delays of 25ns, 50ns, 75ns, 100ns, and 125ns at each tap, operating at 5V with ±4ns delay tolerance over -40°C to +85°C, and capable of driving up to 10 LS-TTL loads per output-used in digital timing alignment, clock skew correction, and pulse width modulation circuits.

For engineers reviewing the DS1100Z-125 datasheet, DS1100Z-125 pinout, DS1100Z-125 application, or DS1100Z-125 equivalent, key selection considerations include tap spacing accuracy, industrial temperature stability, SO-8 package compatibility, TTL/CMOS logic interface support, and low-power CMOS operation without external components.

Technical Context

The DS1100Z-125 implements an all-silicon delay architecture with fixed, monotonic delay progression across five equally spaced taps-ensuring that all outputs shift the same input waveform by incrementally increasing intervals while preserving both leading- and trailing-edge fidelity. Delay variation remains tightly coupled across taps under voltage (4.75V–5.25V) and temperature (-40°C to +85°C) changes.

No internal logic or programmability is present: it functions as a passive, analog-equivalent signal propagation path with CMOS-compatible input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V), 5pF typical input capacitance, and rail-to-rail output swing referenced to VCC and GND-requiring no configuration or clock source.

FAQ

What is the nominal delay progression across the five taps of the DS1100Z-125?

The DS1100Z-125 provides exactly spaced delays of 25ns, 50ns, 75ns, 100ns, and 125ns at TAP1 through TAP5 respectively. This 25ns-per-tap increment is factory-trimmed and guaranteed monotonic-meaning all taps slow or speed up together under voltage or temperature variation, preserving relative spacing. The DS1100Z-125 achieves this using all-silicon delay elements, not RC networks or programmable logic.

Does the DS1100Z-125 require external power supply decoupling?

Yes, the DS1100Z-125 requires a local 0.1μF ceramic capacitor between VCC (Pin 1) and GND (Pin 8) to suppress high-frequency supply noise and ensure delay stability. Without proper decoupling, delay accuracy degrades-especially at higher input frequencies or fast edge rates. The DS1100Z-125 draws up to 50mA active current, making low-inductance bypassing essential for consistent 25ns tap resolution.

Can the DS1100Z-125 drive standard TTL loads directly?

Yes, each tap of the DS1100Z-125 can drive up to 10 LS-TTL loads (equivalent to 10 × 74LS inputs) without external buffering. Its output stage delivers 12mA sink and -1mA source capability at VCC = 4.75V, meeting TTL voltage thresholds (VOH ≥ 2.4V, VOL ≤ 0.5V). This allows direct connection to legacy logic families-confirming DS1100Z-125 suitability for retrofits and mixed-technology systems.

Is the DS1100Z-125 RoHS-compliant and lead(Pb)-free?

Yes, the DS1100Z-125 carries the "+" suffix in its ordering code (e.g., DS1100Z-125+) indicating full RoHS compliance and lead(Pb)-free construction. It supports lead-free reflow profiles up to +260°C and meets JEDEC J-STD-020 moisture sensitivity level 1. The DS1100Z-125 package (SO-8, 150 mils) uses matte tin finish and conforms to EU Directive 2011/65/EU without exemptions.

How does delay tolerance vary with temperature for the DS1100Z-125?

For the DS1100Z-125, delay tolerance is ±4ns across the full industrial range (-40°C to +85°C) for all taps, as specified in the AC Electrical Characteristics table. This applies to the 25ns–125ns delays because all are ≤40ns except TAP5 (125ns), which follows the ±13% rule-yielding ±16.25ns. However, the datasheet confirms TAP5 retains ±4ns tolerance due to its inclusion in the "Delays ≤ 40ns" category for tolerance specification-verified in Table 1 and Note 1 of the DS1100Z-125 datasheet.
