Product details
Overview
DS1100LZ-20 from Maxim Integrated is a 3.3V, 5-tap silicon delay line delivering precise fixed delays of 4ns, 8ns, 12ns, 16ns, and 20ns across its taps. It operates over -40°C to +85°C, supports TTL/CMOS logic levels, and drives up to 10 × 74LS loads per tap. Used in timing alignment, pulse shaping, and clock deskew in high-speed digital systems.
For engineers reviewing the DS1100LZ-20 datasheet, DS1100LZ-20 pinout, DS1100LZ-20 application, or DS1100LZ-20 equivalent, key selection factors include tap delay accuracy (±2ns at +25°C), leading/trailing edge matching, 3.3V supply tolerance (3.0V–3.6V), SO-8 package compatibility, and industrial temperature operation.
Technical Context
The DS1100LZ-20 implements an all-silicon delay architecture with five equally spaced, non-inverting output taps. Each tap reproduces the input logic state after a fixed, factory-trimmed delay-TAP 1 = 4ns, TAP 2 = 8ns, TAP 3 = 12ns, TAP 4 = 16ns, TAP 5 = 20ns-with ±2ns tolerance at +25°C/3.3V.
It guarantees matched propagation for both rising and falling edges (tPLH ≈ tPHL), maintains unidirectional delay drift across voltage (3.0V–3.6V) and temperature (-40°C to +85°C), and features low-power CMOS design with 10mA typical active current at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - Ensures stable operation in 3.3V systems with ±0.3V margin. |
| Nominal Tap Delays | TAP1=4ns, TAP2=8ns, TAP3=12ns, TAP4=16ns, TAP5=20ns - Fixed, factory-calibrated delays for deterministic signal alignment. |
| Delay Tolerance | ±2ns (≤40ns taps, +25°C/3.3V) - Enables sub-nanosecond timing budget control in critical path applications. |
| Output Drive | 8mA sink / -1mA source - Sufficient to drive 10 × 74LS loads without external buffering. |
| Operating Temp | -40°C to +85°C - Qualified for industrial-grade embedded and communications equipment. |
| Input Capacitance | 5–10pF - Minimizes loading on upstream drivers and preserves signal integrity at high frequencies. |
Pinout & Package
DS1100LZ-20 is housed in an 8-pin SOIC (150-mil) surface-mount package, optimized for automated assembly and PCB space efficiency.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS-compatible signals (VIH ≥ 2.0V, VIL ≤ 0.8V). |
| 2 | TAP 2 | Second delay output (8ns), non-inverting, capable of driving 10 × 74LS loads. |
| 3 | TAP 4 | Fourth delay output (16ns), identical electrical characteristics to other taps. |
| 4 | GND | Digital ground reference; requires low-impedance connection to minimize noise coupling. |
| 5 | TAP 5 | Fifth delay output (20ns); maximum delay tap, same rise/fall time (2.0–2.5ns) as others. |
| 6 | TAP 3 | Third delay output (12ns); matches TAP 1–TAP 5 in edge fidelity and load capability. |
| 7 | TAP 1 | First delay output (4ns); shortest fixed delay, used for fine-grained timing adjustments. |
| 8 | VCC | +3.3V supply pin; requires local 0.1µF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay line | Eliminates hybrid or ceramic delay reliability risks; enables full CMOS process integration and reflow compatibility. |
| Leading & trailing edge accuracy | tPLH and tPHL match within ±0.5ns - critical for pulse-width preservation in data strobing and clock recovery. |
| Five equally spaced taps | Enables linear interpolation between delays (e.g., 4ns steps) without external logic or FPGA resources. |
| Vapor-phase & IR solderable | SO-8 package qualified for standard lead-free reflow profiles (peak +260°C), supporting high-yield manufacturing. |
| Stable delay vs. temp/voltage | Unidirectional drift ensures monotonic timing behavior - simplifies worst-case timing analysis across operating conditions. |
Applications
| High-Speed Data Capture | Logic Glitch Suppression |
|---|---|
Use Scenario: Aligning parallel data and strobe signals in ADC/DAC interfaces where setup/hold margins are sub-5ns. IC Role / Device Role / Timing Role: DS1100LZ-20 provides calibrated, low-jitter delay on the strobe path to compensate for trace skew. Use Value: Achieves deterministic 4ns–20ns alignment increments without PLL lock time or programmable latency overhead. | Use Scenario: Removing narrow asynchronous glitches (<10ns) from reset or interrupt lines before entering synchronous logic domains. IC Role / Device Role / Timing Role: DS1100LZ-20 acts as a hardware-based pulse-width filter using dual-tap XOR (e.g., IN and TAP1) to reject pulses shorter than 4ns. Use Value: Eliminates need for multi-stage flip-flop synchronizers or FPGA-based debouncers in safety-critical control paths. |
| Serial Clock Deskew | Test Pattern Generation |
Use Scenario: Equalizing arrival times of multiple serialized clock lanes (e.g., JESD204B) across PCB traces with varying lengths. IC Role / Device Role / Timing Role: DS1100LZ-20 applies discrete, known delays to individual clock outputs to cancel inter-lane skew. Use Value: Enables deterministic deskew resolution down to 4ns steps, improving eye opening without dynamic calibration. | Use Scenario: Generating controlled-delay stimulus patterns for IC test fixtures or boundary-scan validation. IC Role / Device Role / Timing Role: DS1100LZ-20 produces repeatable, jitter-free delayed copies of a master trigger for multi-point sampling. Use Value: Provides five independent, calibrated delay channels from one compact SO-8 device-reducing fixture component count and layout complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-25 | Delays: 5ns/10ns/15ns/20ns/25ns - 5ns step instead of 4ns; ±2ns tolerance same. | Used where coarser 5ns alignment granularity is acceptable or required for margin expansion. | Select when system timing budgets allow 5ns resolution and longer minimum delay (5ns vs. 4ns) is preferred. |
| DS1100LU-20 | Identical delay values and specs, but in 8-pin µMAX (3mm × 3mm) package - 60% smaller footprint than SO-8. | Suitable for space-constrained portable or modular designs where board area is premium. | Choose DS1100LU-20 only if µMAX package compatibility and reflow profile are verified in your assembly process. |
Compared with DS1100LZ-25 and DS1100LU-20, the DS1100LZ-20 uniquely delivers 4ns minimum delay in the industry-standard SO-8 package-enabling finest-grain alignment in legacy or high-reliability layouts without footprint redesign.

FAQ
What is the nominal delay value for each tap of the DS1100LZ-20?
The DS1100LZ-20 provides five fixed delays: TAP 1 = 4ns, TAP 2 = 8ns, TAP 3 = 12ns, TAP 4 = 16ns, and TAP 5 = 20ns. These values are factory-trimmed and specified at +25°C and VCC = 3.3V. The DS1100LZ-20 datasheet confirms ±2ns tolerance for all taps under those conditions, with wider tolerances across full temperature and voltage ranges.
Does the DS1100LZ-20 support both rising and falling edge delays with equal precision?
Yes, the DS1100LZ-20 is explicitly designed to reproduce both leading and trailing edges with equal precision. Its tPLH (rising-edge delay) and tPHL (falling-edge delay) are matched within ±0.5ns under typical conditions. This edge fidelity is confirmed in the DS1100LZ-20 datasheet's AC Electrical Characteristics table and Timing Diagram (Figure 2), ensuring pulse-width integrity in applications like strobe alignment and glitch filtering.
What is the recommended power supply decoupling for the DS1100LZ-20?
A 0.1µF ceramic capacitor placed as close as possible to the VCC (pin 8) and GND (pin 4) pins is required for stable DS1100LZ-20 operation. The DS1100LZ-20 datasheet specifies this in the Test Conditions section and emphasizes low-inductance placement to suppress switching noise that could affect delay accuracy. Additional bulk capacitance (e.g., 4.7µF) may be added nearby for systems with shared rail noise.
Can the DS1100LZ-20 drive standard TTL loads directly?
Yes, the DS1100LZ-20 can drive up to 10 × 74LS loads per tap, as stated in the General Description. Its IOL = 8mA (min) and IOH = -1mA (min) at VCC = 3.0V meet 74LS input current requirements. However, for heavier loads or longer traces, verify signal integrity using the DS1100LZ-20's 2.0–2.5ns rise/fall times and 5–10pF input capacitance to avoid timing violations.
Is the DS1100LZ-20 RoHS-compliant and lead(Pb)-free?
Yes, the DS1100LZ-20 is RoHS-compliant and lead(Pb)-free, indicated by the "+" suffix in its ordering code (e.g., DS1100LZ-20+). The DS1100LZ-20 datasheet confirms it is qualified for lead-free reflow with a peak temperature of +260°C. This compliance is verified in the Ordering Information and Package Information sections, and applies to both tape-and-reel and tube packaging variants.
