Product details
Overview
DS1088LU-02A+ 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 requires no external timing components, features active-low power-down control (PDN), and delivers rail-to-rail CMOS-compatible output into 15pF load. It serves as a low-cost, single-output clock source in space-constrained peripherals.
For engineers reviewing the DS1088LU-02A+ datasheet, DS1088LU-02A+ pinout, DS1088LU-02A+ application, or DS1088LU-02A+ 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 capacitors.
Technical Context
The DS1088LU-02A+ 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 for frequency accuracy.
Power-down is asserted via logic-low on PDN, disabling the oscillator within ≤7µs and reducing supply current to ≤10µA. Output stabilization occurs after ~512 internal clock cycles (tSTAB ≈ 100µs at 2.048MHz), and duty cycle remains 40–60% across operating conditions.

FAQ
What is the exact output frequency of DS1088LU-02A+?
The DS1088LU-02A+ is factory-programmed to deliver a precise 2.048MHz square-wave output. This value is trimmed and verified during manufacturing and is guaranteed across the full operating temperature and voltage range (–20°C to +85°C, 2.7V–3.6V) with ±1% tolerance. No configuration or external components are needed to achieve this frequency.
Does DS1088LU-02A+ require external capacitors or crystals?
No, the DS1088LU-02A+ does not require external timing components. It integrates a factory-calibrated VCO and prescaler, eliminating the need for crystals, load capacitors, or feedback resistors. Only 0.01µF and 0.1µF ceramic decoupling capacitors on VCC are required per the datasheet for stable operation.
How does the power-down function work on DS1088LU-02A+?
The DS1088LU-02A+ enters power-down mode when the PDN pin is driven low. The oscillator disables within ≤7µs, reducing supply current to ≤10µA. To ensure clean disable, PDN must remain low for at least two output cycles plus 10µs. The output goes high-impedance during power-down.
What package type and pin count does DS1088LU-02A+ use?
The DS1088LU-02A+ uses an 8-pin µSOP package (package code U8+1, outline 21-0036). It has two VCC pins (2,3), two GND pins (4,5), one OUT (1), one PDN (6), and two DNC pins (7,8) that must remain unconnected. The exposed pad is not electrically connected.
Is DS1088LU-02A+ RoHS-compliant and lead-free?
Yes, DS1088LU-02A+ is RoHS-compliant and lead-free. The "+" suffix in the part number explicitly denotes a lead(Pb)-free/RoHS-compliant package, as confirmed in Maxim's Ordering Information table and Package Information section.
