Product details
Overview
DS1088LU-16+ from Maxim Integrated is a factory-calibrated, fixed-frequency EconOscillator™ generating a 16.6MHz square-wave output with ±1.0% frequency tolerance over voltage and temperature, 2.7V–3.6V supply, and active-low power-down control - used as a timing reference in POS terminals, cable modems, and computer peripherals.
For engineers reviewing the DS1088LU-16+ datasheet, DS1088LU-16+ pinout, DS1088LU-16+ application, or DS1088LU-16+ equivalent, key selection criteria include guaranteed 16.6MHz output stability, µSOP-8 package compatibility, power-down current ≤10µA, and no external timing components required.
Technical Context
The DS1088LU-16+ integrates a voltage-controlled oscillator (80–160MHz range) followed by a programmable prescaler (÷1, ÷2, ..., ÷256) to deliver its factory-set 16.6MHz output. It uses on-chip EEPROM to store configuration, eliminating external components.
Power-down mode disables the oscillator core and output within ≤7µs; recovery requires ≥100µs stabilization time (≈512 cycles at 16.6MHz). Output drive capability supports 15–50pF load capacitance with 40–60% duty cycle across operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 16.6MHz - factory-trimmed, no calibration needed in system |
| Frequency Tolerance | ±1.0% over full voltage (2.7–3.6V) and temperature (-20°C to +85°C) - ensures timing margin for synchronous logic |
| Supply Voltage | 2.7V to 3.6V - compatible with 3.3V logic rails and low-power embedded systems |
| Power-Down Current | 10µA max - enables battery-backed or ultra-low-power sleep states |
| Output Load Drive | 15pF to 50pF - supports standard CMOS input loads without external buffering |
| Duty Cycle | 40–60% at fO < 80MHz - meets setup/hold timing requirements for most digital interfaces |
| Power-Up Stabilization | 100µs - defines minimum wait time before clock is valid for system initialization |
Pinout & Package
DS1088LU-16+ is housed in an 8-pin µSOP package (package code U8+1, outline 21-0036), with exposed pad grounded per Maxim land pattern 90-0092.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Square-wave clock output - CMOS-compatible, drives 15–50pF loads directly |
| 2, 3 | VCC | Positive supply - dual pins reduce IR drop and improve decoupling effectiveness |
| 4, 5 | GND | Ground reference - dual pins lower ground impedance and minimize noise coupling |
| 6 | PDN | Active-low power-down control - must be held low ≥2 output cycles + 10µs to enter standby |
| 7, 8 | DNC | Do Not Connect - internally tied to GND; floating or connected pins risk latch-up or ESD path disruption |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed frequency | 16.6MHz output set permanently in EEPROM - eliminates BOM cost and layout space for crystals or trim caps |
| No external timing components | Self-contained oscillator core - removes need for external crystal, load capacitors, or feedback resistors |
| Low-power shutdown | 10µA standby current - enables energy-efficient operation in intermittently active systems like POS terminals |
| Wide supply voltage range | 2.7V–3.6V operation - accommodates battery voltage sag and mixed-voltage board designs |
| Stable duty cycle | 40–60% over voltage/temperature - ensures reliable sampling windows for synchronous peripherals |

FAQ
What is the exact output frequency of DS1088LU-16+?
The DS1088LU-16+ is factory-programmed to deliver a precise 16.6MHz square-wave output. This value is permanently stored in on-chip EEPROM and does not require user calibration. Frequency tolerance is guaranteed at ±1.0% across -20°C to +85°C and 2.7V–3.6V supply, as specified in the AC Electrical Characteristics table of the official Maxim datasheet.
Does DS1088LU-16+ require external components to operate?
No, DS1088LU-16+ requires no external timing components - it contains a fully integrated oscillator core, prescaler, and output driver. Only two decoupling capacitors (0.01µF and 0.1µF ceramic) placed near VCC/GND pins are recommended for optimal noise immunity. No crystal, load capacitors, or feedback resistors are needed, simplifying layout and reducing BOM count.
How does the power-down function work on DS1088LU-16+?
The PDN pin on DS1088LU-16+ is active-low: pulling it low disables the oscillator and output within ≤7µs, reducing supply current to ≤10µA. To ensure clean entry into power-down, the pin must remain low for at least two output cycles plus 10µs. Upon release, DS1088LU-16+ requires ≥100µs to stabilize before delivering a valid 16.6MHz clock.
What package type and footprint does DS1088LU-16+ use?
DS1088LU-16+ uses an 8-pin µSOP package (package code U8+1, outline 21-0036) with a 3mm × 3mm body and 0.5mm pitch. The land pattern is documented as 90-0092 on maximintegrated.com. Pins 7 and 8 are DNC (internally grounded), and the exposed pad must be soldered to GND for thermal and electrical integrity.
Is DS1088LU-16+ RoHS-compliant and lead-free?
Yes, DS1088LU-16+ is RoHS-compliant and lead-free, indicated by the "+" suffix in the part number. Maxim's package documentation confirms this device meets JEDEC J-STD-020 moisture sensitivity level 1 and supports standard Pb-free reflow profiles (peak 260°C). Full compliance documentation is available via Analog Devices' product change notices.
