DS1073Z-100

Overview

The DS1073Z-100 is a fixed-frequency oscillator and divider IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a dual output at a maximum frequency of 100MHz with no external components required for basic operation. The device operates on a 2.7V to 3.6V supply and features user-programmable on-chip dividers (1 to 513) and prescalers (1, 2, or 4). Key electrical parameters include an initial tolerance of ±0.5% and a combined frequency variation of ±1% over the commercial temperature range (-40°C to +85°C industrial). Supply current is typically 40mA active and 0.8µA in power-down mode.

Feature Summary

• Dual fixed-frequency outputs up to 100MHz with programmable internal dividers and prescalers
• No external components required; supports internal clock, external clock, or crystal reference
• User-programmable via 1-Wire protocol with non-volatile EEPROM storage
• Synchronous output gating and selectable power-down or select functions

Applications

• Clock generation for digital systems requiring precise timing references
• Embedded systems needing programmable oscillator frequencies without external crystals
• Industrial control applications utilizing the industrial temperature range specifications

Procurement Notes

Verify the specific suffix Z indicates the SOIC package variant when sourcing. Confirm that the programming hardware utilizes the 1-Wire protocol requirements specified in the datasheet. Ensure the supply voltage remains within the 2.7V to 3.6V range for optimal performance and compliance with the stated accuracy specifications.

Selection Notes

Select the DS1073Z-100 specifically for applications requiring a 100MHz maximum output frequency. Consider the DS1073M/Z variants if lower frequencies such as 80MHz, 66.667MHz, or 60MHz are sufficient. Evaluate the need for industrial temperature rating versus commercial grade, as frequency variation increases from ±1% to ±2.5% in the extended range.

Part Context

The DS1073 series belongs to the EconOscillator family designed to simplify clock generation by integrating the oscillator and divider circuitry into a single package. The 'Z' suffix denotes the 150-mil SOIC package option, distinguishing it from the DIP package variant. This component allows for field programming, enabling design flexibility during board production.
