Product details
Overview
DS1088LU-02A+W 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 is housed in an 8-pin µSOP package. It serves as a low-cost, single-output clock source for embedded peripherals requiring stable, low-jitter timing.
For engineers reviewing the DS1088LU-02A+W datasheet, DS1088LU-02A+W pinout, DS1088LU-02A+W application, or DS1088LU-02A+W equivalent, key selection criteria include its guaranteed 2.048MHz output, 10µA standby current in power-down mode, 100µs power-up stabilization time, and compatibility with standard 0.1µF/0.01µF decoupling networks on VCC/GND.
Technical Context
The DS1088LU-02A+W integrates a voltage-controlled oscillator (80–160MHz range) followed by a factory-programmed prescaler (÷1, ÷2, ..., ÷256) to deliver its precise 2.048MHz output. Its internal EEPROM stores calibration data, eliminating need for external crystals or trimming components.
Power management is implemented via the PDN pin: asserting it low disables the oscillator core and output within ≤7µs, reducing supply current to 10µA; release from PDN initiates a 512-cycle stabilization delay (~100µs at 2.048MHz) before valid output resumes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 2.048 MHz - factory-trimmed, no external tuning required |
| Frequency Tolerance | ±1% over full temperature (-20°C to +85°C) and supply (2.7V–3.6V) - ensures timing margin in consumer-grade systems |
| Supply Voltage | 2.7V to 3.6V - compatible with 3.3V logic rails and battery-backed operation |
| Standby Current | 10 µA in power-down mode - enables ultra-low-power sleep states in portable peripherals |

Pinout & Package
DS1088LU-02A+W is packaged in an 8-pin µSOP (U8+1 outline, land pattern 90-0092), with exposed pad grounded per Maxim's recommended layout. Pin 1 is OUT; pins 2 and 3 are VCC; pins 4 and 5 are GND; pin 6 is active-low PDN; pins 7 and 8 are DNC (internally grounded, must remain unconnected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Oscillator Output | CMOS-compatible square wave; drives up to 50pF load directly |
| 2, 3 - VCC | Power Supply | Primary supply input; requires dual decoupling (0.1µF + 0.01µF ceramic) |
| 4, 5 - GND | Ground Reference | Signal and power return; connects to exposed thermal pad |
| 6 - PDN | Active-Low Power-Down Control | Pull high to enable; pull low ≥2 cycles + 10µs to enter 10µA standby |
| 7, 8 - DNC | Do Not Connect | Internally tied to GND; floating or soldered causes no functional impact |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Calibrated Output | 2.048MHz trimmed at wafer level - eliminates post-solder calibration and reduces BOM count |
| No External Timing Components | Self-contained oscillator core - removes crystal, load caps, and matching network from PCB |

FAQ
What is the exact output frequency of DS1088LU-02A+W?
The DS1088LU-02A+W 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 (2.7V–3.6V) and temperature (-20°C to +85°C), with guaranteed ±1% tolerance. No external components or configuration are needed to achieve this frequency - it is fixed and ready on power-up.
Does DS1088LU-02A+W require external capacitors or resistors?
No, DS1088LU-02A+W requires no external timing components. Its oscillator core and prescaler are fully integrated and factory-trimmed. Only two decoupling capacitors (0.1µF and 0.01µF ceramic) on the VCC–GND path are mandatory for stable operation - these are power-supply filtering components, not timing elements. All frequency-setting and stabilization logic resides internally.
How does the power-down function work on DS1088LU-02A+W?
The DS1088LU-02A+W uses an active-low PDN pin (Pin 6). When pulled low (≤0.3×VCC), the device enters power-down mode within ≤7µs, disabling the oscillator and driving OUT low. Supply current drops to 10µA. To re-enable, PDN must be held high for ≥2 output cycles plus 10µs deglitching time; output then stabilizes in 100µs. This behavior is fully specified in the DS1088LU-02A+W datasheet.
What package type and footprint does DS1088LU-02A+W use?
DS1088LU-02A+W uses an 8-pin µSOP package (package code U8+1, outline 21-0036, land pattern 90-0092). It measures 3.0mm × 3.0mm with 0.5mm pitch and includes an exposed thermal pad connected to GND. Pins 7 and 8 are DNC (internally grounded); all other pins match the functional pinout shown in the DS1088LU-02A+W datasheet Figure "Pin Configuration".
Is DS1088LU-02A+W RoHS-compliant and lead-free?
Yes, DS1088LU-02A+W is RoHS-compliant and lead-free. The "+" suffix in the part number denotes compliance per Maxim Integrated's packaging standards. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and supports reflow soldering at peak 260°C. Full environmental compliance documentation, including Pb-free status and halogen content, is available in Maxim's official package data for DS1088LU-02A+W.
