Analog Devices Inc./Maxim Integrated DS1110LE-100+T&R

Overview

DS1110LE-100+T&R from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 10ns increments (10–100ns total), ±5% or ±2ns delay accuracy at 3.3V/+25°C, TTL/CMOS-compatible I/O, and operation from −40°C to +85°C in a 14-pin TSSOP package - used for clock skew correction and signal alignment in high-speed digital test equipment.

For engineers reviewing the DS1110LE-100+T&R datasheet, DS1110LE-100+T&R pinout, DS1110LE-100+T&R application, or DS1110LE-100+T&R equivalent, key selection criteria include tap spacing resolution (10ns), leading/trailing-edge matching tolerance, supply voltage range (2.7V–3.6V), industrial temperature rating, and TSSOP-14 footprint compatibility with automated assembly.

Technical Context

The DS1110LE-100+T&R implements a monolithic silicon delay chain with 10 fixed-output taps derived from a single input signal path. Each tap provides deterministic propagation delay with matched rise/fall edge timing, enabling precise phase alignment without external PLLs or buffers.

It operates across 2.7V–3.6V with stable delay vs. voltage (±0.3% change over VCC range) and temperature (±3% over −40°C to +85°C), and supports up to 10 LS-TTL loads per tap while consuming ≤150mA active current at max frequency.

FAQ

What is the exact delay value for each tap in DS1110LE-100+T&R?

The DS1110LE-100+T&R provides 10 equally spaced taps with nominal delays of 10ns, 20ns, 30ns, 40ns, 50ns, 60ns, 70ns, 80ns, 90ns, and 100ns from the IN pin. These values are specified at 3.3V and +25°C, with tolerance of ±5% or ±2ns (whichever is greater). The tap numbering corresponds directly to increasing delay order, and all taps reproduce both rising and falling edges with matched precision.

Does DS1110LE-100+T&R support both rising and falling edge delays with equal accuracy?

Yes, the DS1110LE-100+T&R produces both leading-edge (tPLH) and trailing-edge (tPHL) delays with identical tolerance specifications - ±5% or ±2ns - across all 10 taps. This edge-matching capability ensures preserved pulse width and duty cycle integrity, making DS1110LE-100+T&R suitable for applications requiring symmetrical timing such as clock deskewing and gated signal generation.

What is the maximum capacitive load each tap of DS1110LE-100+T&R can drive?

Each tap of the DS1110LE-100+T&R is rated to drive up to 10 LS-TTL loads, equivalent to a 450Ω resistor in parallel with 15pF capacitance. Under these conditions, output voltage levels maintain VIH ≥2.3V and VOL ≤0.5V at VCC = 2.7V. Exceeding this load may degrade delay accuracy and edge fidelity, so proper termination and fanout planning are essential in high-density layouts.

Can DS1110LE-100+T&R operate outside the 3.3V nominal supply?

Yes, the DS1110LE-100+T&R is fully characterized from 2.7V to 3.6V. Delay variation over this range is limited to ±0.3% (typical), and all DC/AC specifications - including input thresholds, output drive, and timing accuracy - remain valid across the full supply range. Operation below 2.7V or above 3.6V violates Absolute Maximum Ratings and may cause functional failure or permanent damage.

Is DS1110LE-100+T&R pin-compatible with other DS1110L series variants?

Yes, all DS1110L series parts - including DS1110LE-125, DS1110LE-200, and DS1110LE-500 - share identical 14-pin TSSOP packaging and pinout. The only difference is the nominal total delay (and thus tap spacing), allowing drop-in replacement during prototyping or design iteration without PCB modification. The DS1110LE-100+T&R fits the same footprint and connects identically to IN, GND, VCC, N.C., and all 10 TAP pins.
