Product details
Overview
DS1088LU-829+ from Maxim Integrated is a factory-calibrated, fixed-frequency EconOscillator™ generating a square-wave clock output at 82.9MHz 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.
For engineers reviewing the DS1088LU-829+ datasheet, DS1088LU-829+ pinout, DS1088LU-829+ application, or DS1088LU-829+ equivalent, key selection considerations include guaranteed 82.9MHz output stability across voltage/temperature, sub-7µs power-down disable timing, 100µA typical standby current, and µSOP-8 package compatibility with high-density PCB layouts.
Technical Context
The DS1088LU-829+ integrates a voltage-controlled oscillator (80–160MHz range) followed by a factory-programmed prescaler (÷1, ÷2, ..., ÷256) to deliver its precise 82.9MHz output. Its EEPROM stores calibration data for frequency accuracy and aging compensation.
Power-down mode disables both oscillator core and output buffer within ≤7µs, reducing supply current to ≤10µA. Output duty cycle remains 40–60% across operating conditions, and startup stabilization time is ~100µs (equivalent to ~512 internal clock cycles).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 82.9MHz - factory-trimmed, no external components required |
| Frequency Tolerance | ±1.0% over full voltage (2.7V–3.6V) and temperature (-20°C to +85°C) range |
| Supply Voltage | 2.7V to 3.6V - compatible with 3.3V logic systems; absolute max VCC = +6.0V |
| Power-Down Current | ≤10µA - enables ultra-low-power sleep states in portable peripherals |
| Output Rise/Fall Time | Typically <5ns - supports clean signal integrity up to 133MHz operation |
| Load Capacitance | 15pF to 50pF - matches standard CMOS input loads without external termination |
| Duty Cycle | 40–60% - ensures balanced timing margins for synchronous logic interfaces |
Pinout & Package
DS1088LU-829+ is housed in an 8-pin µSOP package (package code U8+1, outline 21-0036), with exposed pad grounded per Maxim's land pattern 90-0092. Pins 4 and 5 are GND; pins 2 and 3 are VCC; pin 1 is OUT; 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 15pF load directly; no external buffer needed |
| 2,3 - VCC | Power supply | Must be decoupled with 0.01µF + 0.1µF ceramic caps placed adjacent to pins |
| 4,5 - GND | Ground reference | Low-impedance return path; connects internally to substrate ground |
| 6 - PDN | Active-low power-down enable | Pulled low to disable output in ≤7µs; requires ≥2 output cycles + 10µs deglitching |
| 7,8 - DNC | Do Not Connect | Internally tied to GND; floating or connected traces cause no functional impact |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed frequency | 82.9MHz output trimmed at wafer level - eliminates post-silicon calibration effort |
| No external timing components | Self-contained oscillator core - reduces BOM count and layout area vs. crystal + buffer solutions |
| 1% total frequency variation | Guaranteed over full industrial temp/voltage range - simplifies timing margin analysis |
| Sub-7µs power-down disable | Enables rapid entry/exit from low-power states in battery-operated POS terminals |

FAQ
What is the exact output frequency of DS1088LU-829+?
The DS1088LU-829+ is factory-programmed to deliver a precise 82.9MHz square-wave output. This value is laser-trimmed during manufacturing and guaranteed across the full operating range of -20°C to +85°C and 2.7V–3.6V supply voltage, with total variation limited to ±1.0%.
Does DS1088LU-829+ require external capacitors or resistors to operate?
No. The DS1088LU-829+ is a self-contained oscillator - it requires only two external 0.01µF and 0.1µF ceramic decoupling capacitors on the VCC line. No load capacitors, pull-up/pull-down resistors, or timing components are needed for basic operation of the DS1088LU-829+.
How does the power-down function work on DS1088LU-829+?
The DS1088LU-829+ uses an active-low PDN pin: pulling PDN low disables the internal oscillator and output within ≤7µs. The pin must remain low for at least two output cycles plus 10µs for reliable deglitching. Upon release, output stabilizes in ~100µs - a timing behavior inherent to the DS1088LU-829+ architecture.
What package type is used for DS1088LU-829+?
The DS1088LU-829+ is supplied in an 8-pin µSOP package (3mm × 3mm body, 0.5mm pitch), designated U8+1 per Maxim's package coding. It features an exposed thermal pad connected to GND, and follows land pattern 90-0092 for optimal soldering and thermal performance.
Is DS1088LU-829+ RoHS-compliant and lead-free?
Yes. The "+" suffix in DS1088LU-829+ indicates a lead(Pb)-free and RoHS-compliant package per Maxim Integrated's ordering conventions. The device meets JEDEC J-STD-020 reflow profile requirements, with peak soldering temperature rated at +260°C.
