Analog Devices Inc./Maxim Integrated DS1110LE-100+

Overview

DS1110LE-100+ from Maxim Integrated is a 3V, 10-tap all-silicon delay line with total delay of 100ns, ±5% or ±2ns accuracy at 3.3V/+25°C, 2.7V–3.6V supply range, and TTL/CMOS-compatible outputs-used for precise timing alignment in high-speed digital test and medical synchronization circuits.

For engineers reviewing the DS1110LE-100+ datasheet, DS1110LE-100+ pinout, DS1110LE-100+ application, or DS1110LE-100+ equivalent, key selection factors include tap spacing (10ns), leading/trailing-edge matching, industrial temperature range (−40°C to +85°C), TSSOP-14 package compatibility, and load drive capability (10 × 74LS loads).

Technical Context

The DS1110LE-100+ implements a monolithic silicon delay architecture with fixed, equally spaced taps-each output reproduces the input logic state after a deterministic delay, with identical propagation characteristics for rising and falling edges. It operates without external clocks or configuration registers, relying solely on analog delay-line physics.

Delay stability is maintained across voltage (2.7V–3.6V) and temperature (−40°C to +85°C) via process-compensated design; all taps track unidirectionally-e.g., if Tap 1 slows, all others slow proportionally. Input pulse width minimum is 10ns, and output loading is specified at 15pF + 450Ω per tap.

Key Specifications

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and timing ICs for industrial, medical, and communications applications-with emphasis on reliability, low power, and high integration.

The DS1110L series was developed specifically for deterministic, low-jitter signal delay in digital test, imaging, and synchronization systems-replacing discrete RC networks and programmable logic with a calibrated, monolithic silicon solution.

FAQ

What is the exact delay value for each tap on the DS1110LE-100+?

The DS1110LE-100+ provides 10 equally spaced taps with 10ns increments: TAP1 = 10ns, TAP2 = 20ns, TAP3 = 30ns, TAP4 = 40ns, TAP5 = 50ns, TAP6 = 60ns, TAP7 = 70ns, TAP8 = 80ns, TAP9 = 90ns, and TAP10 = 100ns. These values are specified at 3.3V and +25°C, with tolerance of ±5% or ±2ns (whichever is greater). The DS1110LE-100+ maintains proportional spacing across its full operating temperature and voltage range.

Does the DS1110LE-100+ support both rising- and falling-edge delay accuracy?

Yes, the DS1110LE-100+ guarantees matched leading-edge (tPLH) and trailing-edge (tPHL) delay accuracy-both specified under identical conditions (±5% or ±2ns at 3.3V/+25°C). This ensures preserved pulse width across all taps, critical for applications like gated sampling or clock deskewing where duty cycle integrity matters. The DS1110LE-100+ achieves this via symmetric internal delay-path design, not post-processing or trimming.

Can the DS1110LE-100+ operate from a 2.5V supply?

No, the DS1110LE-100+ is characterized and specified only for 2.7V to 3.6V operation. At 2.5V, timing parameters-including delay accuracy, output drive strength, and input threshold levels-are not guaranteed and may fall outside datasheet limits. Operation below 2.7V risks increased delay variation, reduced noise margin, and potential functional failure. The DS1110LE-100+ must be powered within its validated supply range to ensure compliance with its ±2ns accuracy specification.

Is the DS1110LE-100+ pin-compatible with other DS1110L variants like DS1110LE-200+?

Yes, all DS1110L variants-including DS1110LE-100+, DS1110LE-200+, and DS1110LE-500+-share identical 14-pin TSSOP packaging and pinout. The only difference is total delay (and thus tap spacing), which is factory-trimmed during production. No PCB layout change is needed when substituting between DS1110L variants, provided the application can accommodate the new delay profile and associated timing margins.

What is the maximum recommended input frequency for the DS1110LE-100+?

The DS1110LE-100+ does not specify a maximum input frequency, but imposes a minimum input pulse width (tWI) of 10ns and minimum period of 2×tWI (20ns), implying an effective upper limit of 50MHz for reliable delay fidelity. At higher frequencies, delay accuracy degrades due to input rise/fall time effects and capacitive loading. The DS1110LE-100+'s active current increases linearly with frequency-up to ~150mA at 50MHz with 15pF load per tap-so thermal design must account for this.
