Product details
Overview
DS1135LZ-30 from Maxim Integrated is a 3V, 3-in-1 high-speed silicon delay line delivering precise 30 ns propagation delay (tPLH/tPHL) on all three independent buffered outputs, with ±1.5 ns initial tolerance and ±5.0 ns total variation over -40°C to +85°C and 2.7–3.6 V supply, used in clock skew management and digital signal alignment in FPGA-based timing-critical systems.
For engineers reviewing the DS1135LZ-30 datasheet, DS1135LZ-30 pinout, DS1135LZ-30 application, or DS1135LZ-30 equivalent, this page provides verified delay accuracy, SO-8 package compatibility, input/output edge symmetry, industrial temperature support, and direct replacement context for legacy DS1033 designs.
Technical Context
The DS1135LZ-30 implements three identical, fully buffered all-silicon delay paths with matched tPLH and tPHL characteristics, preserving input signal symmetry via leading- and trailing-edge precision. Each output operates independently with no internal crosstalk coupling.
It functions as a fixed, non-programmable delay element with no control interface, requiring only 3V supply and TTL/CMOS-compatible inputs. Delay stability is maintained across voltage (2.7–3.6 V) and temperature (-40°C to +85°C), with rise/fall times ≤2.5 ns and power-up time ≤1 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 30 ns (tPLH/tPHL), matched across all three channels for synchronized signal alignment |
| Initial delay tolerance | ±1.5 ns at +25°C, 3.3 V - sets baseline timing budget for board-level margining |
| Temp/voltage tolerance | ±5.0 ns over -40°C to +85°C and 2.7–3.6 V - defines worst-case skew envelope in industrial environments |
| Supply voltage | 2.7 V to 3.6 V - compatible with modern 3V logic families and low-power FPGA I/O banks |
| Output rise/fall time | ≤2.5 ns - supports clean transitions into 15 pF loads without added termination |
| Power-up time | ≤1 ms - ensures stable delays after system reset without external sequencing |
| Input pulse width | ≥100% of delay value (i.e., ≥30 ns) - minimum valid input pulse duration for guaranteed delay accuracy |
Pinout & Package
DS1135LZ-30 is housed in an 8-pin SOIC (150-mil) package, RoHS-compliant (Z suffix), with standard 1.27 mm pitch and JEDEC MS-012AC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Dedicated input signals | Three independent CMOS/TTL-compatible inputs driving respective delay paths |
| OUT1, OUT2, OUT3 | Buffered delay outputs | Three isolated, low-skew outputs each delayed by exactly 30 ns from corresponding input |
| VCC | Positive supply | Single 3V rail powering all three delay paths; decoupling required within 10 mm |
| GND | Ground reference | Common return for all inputs, outputs, and internal circuitry; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz aging, shock sensitivity, and EMI susceptibility inherent in crystal-based delay solutions |
| Leading/trailing edge precision | Maintains input duty cycle integrity - critical for clock distribution and data eye alignment |
| Industrial temperature range | Guaranteed 30 ns delay operation from -40°C to +85°C without derating or calibration |
| Vapor-phase & IR reflow compatible | Supports automated SMT assembly per JEDEC J-STD-020; peak temp up to 260°C |
| Low active current | 10 mA typical at 1 µs period - enables use in power-constrained embedded timing nodes |
Applications
| High-Speed FPGA Clock Alignment | PCIe Gen2 Signal Deskew |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1033Z-30+ | Same 30 ns delay but higher initial tolerance (±3.0 ns vs. ±1.5 ns); slower max speed (100 MHz vs. 200+ MHz) | Acceptable for non-critical timing paths where >3 ns skew margin exists | Select DS1135LZ-30 when edge fidelity, industrial temp stability, or sub-ns matching is required |
| MAX961CPE+ | Comparator-based delay with adjustable threshold; not a fixed-delay IC - requires external RC tuning | Suitable only where programmability justifies added design complexity and calibration overhead | Choose DS1135LZ-30 for drop-in, zero-calibration, production-ready 30 ns delay |
Compared with DS1033Z-30+ and MAX961CPE+, DS1135LZ-30 delivers tighter initial delay tolerance, superior temperature/voltage stability, and true 3-in-1 channel independence - making it optimal for deterministic, high-reliability signal alignment without tuning or layout compromise.

FAQ
What is the guaranteed delay accuracy of DS1135LZ-30 over its full operating temperature range?
The DS1135LZ-30 guarantees ±5.0 ns total delay variation over -40°C to +85°C and 2.7–3.6 V supply, combining initial tolerance (±1.5 ns) and additional drift due to temperature and voltage. This is verified per Table 1 and Absolute Maximum Ratings sections of the official Maxim datasheet Rev 8/12, ensuring predictable timing behavior in uncontrolled thermal environments without recalibration.
Does DS1135LZ-30 support 2.5V or 1.8V logic interfaces?
No - DS1135LZ-30 is specified only for 2.7 V to 3.6 V operation. Its VIH (2.0 V min) and VIL (0.8 V max) thresholds are optimized for 3V CMOS/TTL levels. Driving it from 2.5V or 1.8V sources may result in undefined switching or degraded noise margins; DS1135LZ-30 must be powered and interfaced within its rated 3V domain.
Can DS1135LZ-30 be used to delay both rising and falling edges equally?
Yes - DS1135LZ-30 preserves input signal symmetry with matched tPLH and tPHL values (both 30 ns), confirmed in Table 1 and the "Leading and Trailing Edge Precision" feature. This ensures equal delay for both edges, maintaining duty cycle integrity essential for clock distribution and bidirectional data alignment in DS1135LZ-30 applications.
Is DS1135LZ-30 pin-compatible with DS1033Z-30+?
Yes - DS1135LZ-30 and DS1033Z-30+ share identical 8-pin SOIC (150-mil) pinout, pin functions, and footprint. However, DS1135LZ-30 offers improved delay accuracy (±1.5 ns vs. ±3.0 ns), faster edge rates (≤2.5 ns vs. ≤4 ns), and wider voltage range (2.7–3.6 V vs. 4.5–5.5 V), making DS1135LZ-30 a functional upgrade with no PCB changes required.
What is the maximum input frequency supported by DS1135LZ-30?
DS1135LZ-30 supports input periods down to 2× the delay value (i.e., ≥60 ns period), corresponding to ≤16.7 MHz maximum fundamental frequency. This limit arises from the requirement that input pulse width (tWI) be ≥100% of the delay (≥30 ns), as specified in the AC Electrical Characteristics table - a hard constraint for reliable DS1135LZ-30 operation.
