Product details
Overview
DS1088LU-100 from Maxim Integrated is a factory-calibrated, fixed-frequency EconOscillator™ generating a 100.0MHz square-wave clock output with ±1.0% frequency tolerance over -20°C to +85°C and 2.7V–3.6V supply. It requires no external timing components, features a dedicated power-down pin (PDN), and delivers rail-to-rail CMOS-compatible output drive into 15pF load. Used in cable modems and automotive telematics for stable, low-cost system timing.
For engineers reviewing the DS1088LU-100 datasheet, DS1088LU-100 pinout, DS1088LU-100 application, or DS1088LU-100 equivalent, key selection considerations include its 100MHz factory-trimmed output, 8-pin µSOP package, power-down latency under 7µs, and guaranteed ±1.0% total frequency variation across voltage and temperature.
Technical Context
The DS1088LU-100 integrates a voltage-controlled oscillator (80–160MHz range) followed by a programmable prescaler (division by 1, 2, 4…256) to generate its precise 100.0MHz output. Its EEPROM stores factory calibration data, enabling single-output, no-component operation without crystal or capacitor loading.
Power management is implemented via the PDN pin: logic-high enables oscillation; logic-low disables the VCO and output within ≤7µs while reducing supply current to 10µA. The device uses dual VCC and dual GND pins for improved noise immunity and decoupling integrity at high frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 100.0 MHz - factory-trimmed, no external components required |
| Frequency Tolerance | ±1.0% over full voltage (2.7–3.6V) and temperature (-20°C to +85°C) - ensures timing margin in industrial environments |
| Supply Voltage | 2.7V to 3.6V - compatible with 3.3V logic systems and battery-backed designs |
| Power-Down Current | 10 µA - enables ultra-low standby power in portable or energy-sensitive applications |
| Power-Up Stabilization | 100 µs - includes internal 512-cycle stabilization delay for reliable clock assertion |
| Output Load Drive | 15 pF capacitive load - supports standard CMOS fanout without buffer amplification |
| Duty Cycle | 50% ±2% at 100MHz - meets setup/hold timing requirements for synchronous interfaces |
Pinout & Package
DS1088LU-100 is housed in an 8-pin µSOP (micro Small Outline Package) with 0.5mm pitch, thermally enhanced for stable high-frequency operation. Dual VCC and dual GND pins reduce supply impedance and improve PSRR.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | CMOS square-wave clock output; rail-to-rail swing, 15pF load rated |
| 2 | VCC | Primary power supply pin; must be decoupled with 0.1µF + 0.01µF ceramic caps |
| 3 | VCC | Secondary power supply pin; shares same net as Pin 2 for lower supply loop inductance |
| 4 | GND | Primary ground reference; connects to substrate and internal ground plane |
| 5 | GND | Secondary ground pin; reduces ground bounce at 100MHz switching |
| 6 | PDN | Active-high power-down control; <2µs response, requires ≥2 cycles + 10µs low pulse for clean entry |
| 7, 8 | DNC | Do Not Connect; internally tied to ground - must remain unconnected on PCB |
Key Features
| Feature | Design Value |

FAQ
What is the output waveform type and drive capability of DS1088LU-100?
The DS1088LU-100 delivers a CMOS-compatible square wave with rail-to-rail swing (VOH = VCC – 0.4V, VOL = 0.4V) and can drive up to 15pF capacitive load. At 100MHz, it maintains 50% ±2% duty cycle and exhibits typical active supply current of 13mA at 3.3V - verified per DS1088L datasheet Figure toc03.
Does DS1088LU-100 require external components to operate?
No. DS1088LU-100 is a self-contained oscillator: no crystal, no load capacitors, and no feedback resistors are needed. Only two decoupling capacitors (0.1µF and 0.01µF ceramic) on VCC are required per the recommended operating circuit. This eliminates component variability and simplifies layout verification for DS1088LU-100 deployments.
How does the power-down function work on DS1088LU-100?
The PDN pin is active-high: driving it high enables the oscillator; pulling it low disables both the VCO and OUT pin within ≤7µs. To enter power-down, PDN must stay low for at least two output cycles plus 10µs for deglitching. DS1088LU-100 draws just 10µA in this state, making it suitable for battery-backed or intermittent-operation systems.
What is the frequency accuracy specification for DS1088LU-100 over temperature and voltage?
DS1088LU-100 guarantees ±1.0% total frequency variation across the full operating range: -20°C to +85°C and 2.7V to 3.6V supply. This combines voltage variation (±0.35%), temperature variation (±0.7% over -20°C to +25°C and ±0.5% over +25°C to +85°C), and aging (±0.2%) - all specified in the DS1088L oscillator characteristics table.
Is DS1088LU-100 pin-compatible with other variants in the DS1088L family?
Yes. All DS1088LU-x variants - including DS1088LU-02, DS1088LU-10, DS1088LU-16, DS1088LU-66, and DS1088LU-100 - share identical 8-pin µSOP packaging, pinout, and electrical interface. Only the factory-programmed output frequency differs; no PCB redesign is needed when migrating between DS1088LU-100 and other members of the family.
