Product details
Overview
DS1088LU-02A+T from Maxim Integrated is a factory-calibrated, fixed-frequency EconOscillator™ generating a 2.048MHz square-wave output with ±1% frequency tolerance over -20°C to +85°C and 2.7V–3.6V supply. It features an active-low power-down pin (PDN), requires no external timing components, and delivers rail-to-rail CMOS-compatible output into 15pF load. It serves as a low-cost, single-output clock source for embedded peripherals.
For engineers reviewing the DS1088LU-02A+T datasheet, DS1088LU-02A+T pinout, DS1088LU-02A+T application, or DS1088LU-02A+T equivalent, key selection criteria include guaranteed 2.048MHz output stability across voltage/temperature, µSOP-8 package compatibility, power-down current ≤10µA, and absence of external crystal or load capacitors.
Technical Context
The DS1088LU-02A+T integrates a voltage-controlled oscillator (80–160MHz range) followed by a factory-programmed prescaler (÷1 to ÷256) to deliver its precise 2.048MHz output. Its internal EEPROM stores calibration data, enabling stable operation without trimming components.
Power-down mode disables both oscillator core and output buffer within ≤7µs, with recovery requiring ≥100µs stabilization time (≈512 output cycles). Output duty cycle remains 40–60% across voltage and temperature, meeting standard digital clocking requirements for synchronous logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 2.048MHz - exact factory-trimmed value, no user programming required |
| Frequency Tolerance | ±1% over full operating range - ensures timing margin for UART, USB, and peripheral sync |
| Supply Voltage | 2.7V to 3.6V - compatible with 3.3V logic rails and battery-backed systems |
| Power-Down Current | 10µA max - enables ultra-low standby power in portable POS or printer sleep modes |
| Operating Temperature | -20°C to +85°C - supports commercial-grade industrial and office equipment environments |
| Output Load Drive | 15pF typical - sufficient for direct connection to MCU clock inputs without buffering |
| Power-Up Time | 100µs - allows fast wake-up in responsive peripheral subsystems |
Pinout & Package
DS1088LU-02A+T is housed in an 8-pin µSOP package (package code U8+1, outline 21-0036), RoHS-compliant and lead-free. Pin 1 is OUT; pins 2–3 are VCC; pins 4–5 are GND; pin 6 is PDN (active-low); pins 7–8 are DNC (internally grounded, must remain unconnected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Oscillator output | CMOS square wave at 2.048MHz; drives 15pF load directly |
| 2, 3 (VCC) | Power supply | Must be decoupled with 0.01µF + 0.1µF ceramic caps placed adjacent to pins |
| 4, 5 (GND) | Ground reference | Return path for supply and output; connects internally to substrate |
| 6 (PDN) | Active-low enable | Pull high (≥0.7×VCC) to enable; pull low (≤0.3×VCC) to enter 10µA shutdown |
| 7, 8 (DNC) | Do Not Connect | Internally tied to GND; floating or soldered connections risk noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed frequency | 2.048MHz calibrated and stored in on-chip EEPROM - eliminates BOM cost and layout area for crystals |
| No external timing components | Self-contained oscillator core - removes need for load capacitors, crystal, or trimmer |
| Power-down control | Hardware-enabled shutdown via PDN pin - reduces system idle power without software intervention |
| Stable duty cycle | 40–60% over voltage/temperature - ensures reliable edge timing for flip-flop sampling |
| Wide supply range | 2.7V–3.6V operation - accommodates brown-out conditions and Li-ion battery discharge profiles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-frequency oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si51212-D-CM10009 | 2.048MHz, 3.3V, LVCMOS output; ±50ppm initial accuracy (0.005%), lower jitter | Higher precision and lower phase noise; requires external 3.3V regulator if system uses 2.7V rail | Preferred when sub-100ps jitter or telecom-grade timing is required; not drop-in due to tighter voltage spec |
| ABM3B-2.048MHZ-D2Y-T | 2.048MHz quartz crystal (not oscillator); requires external oscillator circuit and load caps | Passive resonator only - adds design complexity, layout sensitivity, and startup delay | Only suitable where lowest BOM cost outweighs design effort and reliability risk of discrete crystal solution |
Compared with Si51212-D-CM10009 and ABM3B-2.048MHZ-D2Y-T, DS1088LU-02A+T offers the simplest integration (no external components), widest supply range (2.7–3.6V), and lowest system-level cost - ideal for cost-sensitive commercial peripherals where ±1% accuracy suffices.

FAQ
What is the exact output frequency of DS1088LU-02A+T?
The DS1088LU-02A+T is factory-programmed to deliver a precise 2.048MHz square-wave output. This value is permanently stored in on-chip EEPROM and calibrated across voltage and temperature - no user configuration or external components are needed to achieve this frequency. The DS1088LU-02A+T maintains ±1% tolerance over its full operating range.
Does DS1088LU-02A+T require external capacitors or crystals?
No, the DS1088LU-02A+T does not require external timing components. It integrates a voltage-controlled oscillator and factory-programmed prescaler, eliminating the need for crystals, load capacitors, or trimming resistors. Only 0.01µF and 0.1µF decoupling capacitors on VCC are required per the datasheet - these serve power integrity, not timing function.
How does the power-down feature work on DS1088LU-02A+T?
The DS1088LU-02A+T enters power-down mode when the PDN pin is driven low (≤0.3×VCC). Output disables within ≤7µs, and supply current drops to ≤10µA. To re-enable, PDN must be pulled high (≥0.7×VCC); the output stabilizes after ≥100µs (≈512 cycles at 2.048MHz). No external reset sequencing is required.
What package type and footprint does DS1088LU-02A+T use?
The DS1088LU-02A+T uses an 8-pin µSOP package (outline 21-0036, land pattern 90-0092), RoHS-compliant and lead-free. Pins 1–8 map to OUT, VCC, VCC, GND, GND, PDN, DNC, DNC. The DNC pins are internally grounded and must remain unconnected on the PCB to avoid noise injection or latch-up.
Is DS1088LU-02A+T suitable for automotive applications?
No, DS1088LU-02A+T is specified for -20°C to +85°C operation and is intended for commercial-grade applications such as printers, copiers, and POS terminals. It is not qualified to AEC-Q200 or rated for extended temperature ranges (e.g., -40°C to +125°C) required in automotive environments.
