DS1073M-60

Overview

The DS1073M-60 is a fixed-frequency oscillator and divider from Analog Devices/Maxim Integrated, operating within a 2.7V to 3.6V supply range. It features dual outputs with a maximum frequency of 60MHz. The device incorporates user-programmable on-chip dividers (1 to 513) and prescalers (1, 2, 4), stored in non-volatile memory. It supports internal, external clock, or crystal references. Key specifications include ±0.5% initial tolerance, ±1% variation over commercial temperature/voltage, and synchronous output gating. The component is available in 8-pin DIP packages.

Feature Summary

• Dual fixed-frequency outputs up to 60MHz with no external components required for basic operation
• User-programmable on-chip dividers (1–513) and prescalers (1, 2, 4) stored in non-volatile EEPROM
• Supports internal oscillator, external clock, or fundamental mode crystal reference
• Synchronous output gating prevents truncated pulses; includes power-down mode

Applications

• Clock generation for digital systems requiring precise timing
• Frequency division in communication equipment
• Reference clock sources for microprocessors and FPGAs

Procurement Notes

Verify the specific suffix (e.g., M for DIP, Z for SOIC) matches the required package type. Confirm whether commercial (0°C to +70°C) or industrial (-40°C to +85°C) temperature ratings are needed, as electrical characteristics vary between ranges. Ensure programming requirements are met if factory defaults do not match the target frequency configuration.

Selection Notes

Select the DS1073M-60 variant specifically for a 60MHz maximum output frequency. Consider the DS1073M-66, -80, or -100 models if higher frequencies are required. Evaluate the need for external vs. internal reference based on jitter and stability requirements. Check package availability (DIP vs. SOIC) against board layout constraints.

Part Context

The DS1073 series belongs to Maxim Integrated's EconOscillator family, designed as self-contained oscillator/divider solutions. The 'M' suffix denotes the 300-mil DIP package, while 'Z' indicates the 150-mil SOIC package. These devices eliminate the need for discrete crystals and capacitors when using the internal oscillator, simplifying PCB design.
