DS1089L

3.3V Center Spread-Spectrum EconOscillator™

General Description

Features

The DS1089L is a clock generator that produces a

spread-spectrum (dithered) square-wave output of fre-

quencies from 130kHz to 66.6MHz. The DS1089L is

shipped from the factory programmed at a specific

frequency. The DS1089L is pin-for-pin compatible with

the DS1087L, however, the DS1089L dithers at equal

percentages above and below the center frequency. The

user still has access to the internal frequency divider,

selectable ±1%, ±2%, ±4%, or ±8% dithered output, dith-

ering rate, and programmable output power-down/disable

● Factory-Programmed Square-Wave Generator from

33.3MHz to 66.6MHz

● Center Frequency Remains Constant Independent of

Dither Percentage

● No External Timing Components Required

● EMI Reduction

● Variable Dither Frequency

● User Programmable Down to 130kHz with Divider

(Dependent on Master Oscillator Frequency)

mode through an I C-compatible programming interface.

● ±1%, ±2%, ±4%, or ±8% Selectable Dithered Output

● Glitchless Output-Enable Control

All the device settings are stored in nonvolatile (NV)

EEPROM allowing it to operate in stand-alone applica-

tions. The DS1089L also has power-down and output-en-

able control pins for power-sensitive applications.

● I C-Compatible Serial Interface

● Nonvolatile Settings

Applications

● Power-Down Mode

● Printers

● Copiers

● Programmable Output Power-Down/Disable Mode

● Computer Peripherals

● POS Terminals

● Cable Modems
