DS1075Z-010

Overview

The DS1075Z-010 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 requires no external components for basic operation. The device features dual outputs with frequencies ranging from approximately 30 KHz to 100 MHz, determined by user-programmable on-chip dividers (1–513) and prescalers (1, 2, 4). Key electrical specifications include an initial frequency tolerance of ±0.5%, combined variation over temperature and voltage of ±1%, and long-term stability of ±0.5%. It supports internal, external clock, or crystal references and includes power-down and synchronous output enable functions.

Feature Summary

• Dual fixed-frequency outputs with programmable division ratios
• User-programmable on-chip nonvolatile memory for divider and prescaler settings
• Supports internal oscillator, external clock, or crystal reference inputs
• Synchronous output gating and low-power shutdown mode

Applications

• Clock generation for digital systems requiring precise timing
• Microcontroller and processor clock sources
• Communication interface timing circuits
• Test and measurement equipment clock references

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package type (SOIC or DIP) and suffix codes match specific frequency requirements. Check for obsolescence status as older Maxim products may have limited availability. Ensure programming tools are available if field configuration is required.

Selection Notes

Select based on required output frequency range and reference source preference. Consider power consumption needs; use power-down mode for battery applications. Verify voltage compatibility (single 5V supply). Evaluate package constraints (8-pin SOIC or DIP) against board layout requirements. Program registers prior to final assembly for custom frequencies.

Part Context

The DS1075Z-010 belongs to the DS1075 EconOscillator/Divider family. The 'Z' suffix typically denotes the SOIC package variant, while 'M' indicates DIP. Other variants like DS1075-100 specify maximum operating frequencies (e.g., 100 MHz). This component integrates oscillator and divider functions into a single chip, reducing bill-of-materials complexity compared to discrete solutions.

Replacement Considerations

Direct replacements may be limited due to proprietary programming protocols. Consider generic programmable oscillators or PLL-based clock generators if reprogramming capability is not strictly required. Verify pinout compatibility and electrical characteristics before substitution.
