DS1075Z-80

Overview

The DS1075Z-80 is a fixed-frequency oscillator and divider from the DS1075 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply and generates dual outputs within a frequency range of approximately 30 KHz to 100 MHz. The device features user-programmable on-chip dividers (1–513) and prescalers (1, 2, 4), with settings stored in nonvolatile memory. Key electrical specifications include an initial frequency tolerance of ±0.5% at 25°C, combined variation of ±1% over temperature and voltage, and a typical supply current of 50 mA. It supports internal, external clock, or crystal references.

Feature Summary

• Dual fixed-frequency outputs with programmable division ratios
• On-chip nonvolatile memory for storing user-defined divider and prescaler values
• Supports internal oscillator, external clock input, or crystal reference
• Synchronous output gating and power-down mode for low standby current

Applications

• Clock generation for digital systems requiring precise timing
• Microprocessor and microcontroller clock sources
• Communication equipment requiring stable frequency references
• Test and measurement instrumentation

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package type (SOIC) and suffix compatibility. Check for end-of-life status as older Maxim/Analog Devices components may have limited availability. Ensure programming tools are available if field configuration is required.

Selection Notes

Select based on required output frequency and reference source. The Z suffix indicates SOIC packaging; M indicates DIP. Ensure supply voltage matches 5V nominal. Consider power-down requirements and output enable logic levels. Verify temperature range meets application needs (0°C to 70°C).

Part Context

The DS1075Z-80 belongs to the DS1075 EconOscillator/Divider family. The -80 suffix denotes a maximum operating frequency of 80.000 MHz. Other variants include -100 (100 MHz), -66 (66.667 MHz), and -60 (60.000 MHz). The Z suffix specifically identifies the 150-mil SOIC package option.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Cross-reference with other fixed-frequency oscillators from Analog Devices or Maxim Integrated that support similar frequency ranges and pinouts. Verify functional equivalence regarding programming interface and output drive capabilities.
