DS1075M-66

Overview

The DS1075M-66 is a fixed-frequency oscillator and divider from the DS1075 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply (4.75V to 5.25V) and features dual outputs with a maximum frequency of 66.667 MHz. The device includes user-programmable on-chip dividers (range 1–513) and prescalers (1, 2, or 4), with settings stored in nonvolatile EEPROM. It supports internal, external clock, or crystal references, offers synchronous output gating, and provides a power-down mode. Initial tolerance is ±0.5%, with variation over temperature and voltage limited to ±1%.

Feature Summary

• Dual fixed-frequency outputs up to 66.667 MHz with no external components required.
• User-programmable on-chip dividers (1–513) and prescalers (1, 2, 4) stored in nonvolatile memory.
• Supports internal oscillator, external clock, or crystal reference inputs.
• Synchronous output enable and low-power shutdown modes.

Applications

• Clock generation for digital systems requiring precise frequency division.
• Embedded systems needing programmable timing references.
• Industrial control applications utilizing stable 5V clock signals.

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package type (8-pin DIP or SOIC) matches design requirements. Check current lifecycle status as availability may be restricted. Ensure programming tools are compatible with the 1-Wire interface if field configuration is needed.

Selection Notes

Select the DS1075M-66 variant specifically for a 66.667 MHz maximum output frequency. Consider the DS1075M-100 or DS1075M-80 if higher frequencies are required. Verify that the 5V supply voltage aligns with system power rails. Evaluate whether the built-in programmability meets long-term design flexibility needs.

Part Context

The DS1075 series serves as an EconOscillator/Divider solution, eliminating the need for discrete crystal and buffer components. The 'M' suffix denotes the 300-mil DIP package option. This part integrates master oscillation, prescaling, and division into a single IC, simplifying board layout and reducing component count compared to traditional oscillator designs.

Replacement Considerations

Direct replacements within the same family include DS1075M-100 (100 MHz) and DS1075M-80 (80 MHz). Cross-family alternatives require verification of pin compatibility and electrical specifications. No other specific substitute part numbers are confirmed in public documentation.
