Product details
Overview
DS1088LU-24+ from Maxim Integrated is a factory-calibrated, fixed-frequency EconOscillator™ generating a 24MHz square-wave clock output without external timing components. It operates from 2.7V to 3.6V, delivers ±1.0% frequency stability over voltage and temperature, and features an active-low power-down pin for low-power system control. It is used in POS terminals and computer peripherals requiring stable, low-cost timing.
For engineers reviewing the DS1088LU-24+ datasheet, DS1088LU-24+ pinout, DS1088LU-24+ application, or DS1088LU-24+ equivalent, this page provides verified electrical parameters, package mapping, functional role in clock tree design, and validated alternative options for cost-sensitive embedded timing applications.
Technical Context
The DS1088LU-24+ integrates a voltage-controlled oscillator (80–160MHz range) with a factory-programmed prescaler (÷1, ÷2, ..., ÷256) to deliver its precise 24MHz output. Its EEPROM-based configuration ensures permanent frequency setting without runtime programming.
It uses an internal deglitching circuit requiring PDN to remain low for ≥2 output cycles + 10µs to enter power-down mode. Power-up stabilization requires ~512 internal clock cycles (tSTAB), resulting in a typical 100µs delay before valid output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 24MHz - exact factory-trimmed value; no external crystal or load required. |
| Frequency Tolerance | ±1.0% over full voltage (2.7–3.6V) and temperature (-20°C to +85°C) - enables reliable timing without calibration in consumer-grade systems. |
| Supply Voltage | 2.7V to 3.6V - compatible with 3.3V logic domains and battery-backed operation down to 2.7V. |
| Power-Down Current | 10µA - reduces system standby power significantly when clock is not needed. |
| Output Drive | VOH ≥ VCC–0.4V @ -4mA, VOL ≤ 0.4V @ 4mA - drives standard CMOS loads up to 15pF without buffer. |
| Duty Cycle | 40–60% at 24MHz - meets setup/hold timing margins for synchronous digital interfaces. |
| Power-Up Time | 100µs max - defines minimum reset release delay before clock-dependent logic can initialize. |
Pinout & Package
DS1088LU-24+ is housed in an 8-pin µSOP (U8+1) package, 3.0mm × 3.0mm, 0.5mm pitch, RoHS-compliant. Thermal pad is not present; substrate is internally grounded.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Oscillator Output | CMOS-compatible square-wave output; directly clocks microcontrollers, USB PHYs, or FPGA I/O banks. |
| 2, 3 (VCC) | Power Supply | Dual VCC pins reduce supply impedance; require local 0.01µF + 0.1µF ceramic decoupling per pin. |
| 4, 5 (GND) | Ground | Dual GND pins provide low-inductance return path; must be connected to solid ground plane. |
| 6 (PDN) | Active-Low Power-Down | Pull high (≥0.7×VCC) to enable; pull low (≤0.3×VCC) to disable output and reduce current to 10µA. |
| 7, 8 (DNC) | Do Not Connect | Internally tied to GND; must remain unconnected on PCB to avoid parasitic coupling or solder shorts. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Calibrated Fixed Frequency | 24MHz output trimmed at wafer/test level - eliminates BOM cost and board space for crystal + load caps. |
| No External Timing Components | Self-contained oscillator core - removes risk of layout sensitivity, EMI from crystal traces, and tuning drift. |
| Low-Power Power-Down Mode | 10µA shutdown current - supports dynamic clock gating in portable or energy-certified devices. |
| Wide Operating Temperature | -20°C to +85°C - suitable for commercial and industrial peripheral enclosures without thermal derating. |
| Stable Duty Cycle | 40–60% across voltage/temperature - ensures consistent timing margins for DDR, USB, or PCIe reference clock paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-frequency oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-24.0000M-GR | Programmable I²C-configurable XO; ±20ppm stability; 3.3V only; 4-pin 2.5×2.0mm SMD. | Supports field reconfiguration and spread-spectrum modes; higher precision but higher cost and complexity. | Choose for designs needing future frequency flexibility or tighter stability; not drop-in due to different pin count and interface. |
| AK2-24.000MHZ-E | Standard quartz-based XO; ±50ppm stability; 3.3V; 4-pin 3.2×2.5mm SMD; no power-down pin. | Lacks PDN control and consumes ~5mA active current; requires external crystal load caps if using fundamental-mode variant. | Choose where ultra-low standby power is not required and board space allows larger footprint; no power-down capability limits use in battery-aware systems. |
Compared with Si510-24.0000M-GR and AK2-24.000MHZ-E, DS1088LU-24+ offers lowest BOM cost and smallest footprint among 24MHz oscillators with integrated power-down, making it optimal for cost-constrained, space-limited commercial peripherals.

FAQ
What is the exact output frequency of DS1088LU-24+?
The DS1088LU-24+ is factory-programmed to deliver precisely 24.000MHz. This value is permanently stored in on-chip EEPROM and does not require external configuration. The device achieves ±1.0% total frequency variation across its operating voltage (2.7V–3.6V) and temperature (-20°C to +85°C) ranges, as specified in the official Maxim datasheet Rev 3 (2015).
Does DS1088LU-24+ require external capacitors or resistors?
No, DS1088LU-24+ requires no external timing components. It integrates a fully self-contained oscillator core with factory-trimmed frequency. Only mandatory external components are two ceramic decoupling capacitors (0.01µF and 0.1µF) placed near the VCC and GND pins. No load capacitors, pull-ups, or series resistors are needed for basic operation.
How does the power-down function work on DS1088LU-24+?
The DS1088LU-24+ enters power-down mode when the PDN pin is driven low (≤0.3×VCC). The output disables within ≤7µs, and supply current drops to 10µA. To ensure reliable entry, PDN must remain low for at least two output cycles plus 10µs. Upon release, the device requires ~100µs (512 internal clock cycles) before stable 24MHz output resumes.
What is the package type and footprint for DS1088LU-24+?
DS1088LU-24+ uses an 8-pin µSOP package (package code U8+1), measuring 3.0mm × 3.0mm with 0.5mm pitch. Land pattern number 90-0092 applies. Pins 7 and 8 are DNC (internally grounded) and must remain unconnected on the PCB. The package is RoHS-compliant and lead(Pb)-free, indicated by the "+" suffix.
Can DS1088LU-24+ drive a 50pF load?
DS1088LU-24+ is characterized for CL = 15pF (max recommended); operation into 50pF exceeds specification and may degrade duty cycle, rise/fall times, and frequency stability. For heavier loads, add a dedicated buffer (e.g., SN74LVC1G04) between DS1088LU-24+ and the load. The datasheet explicitly states performance is guaranteed only up to 15pF, and loading beyond that risks violating AC timing specs.
