DS1075M-100

Overview

The DS1075M-100 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 and generates dual outputs within a frequency range of approximately 30 KHz to 100 MHz. The device features 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, offering 0.5% initial tolerance and 1% variation over temperature and voltage. The component is housed in an 8-pin DIP package.

Feature Summary

• Dual fixed-frequency outputs with programmable prescaler and divider
• Nonvolatile memory for storing user-defined configuration registers
• Supports internal oscillator, external clock, or crystal reference inputs
• Synchronous output gating and power-down mode for low standby current

Applications

• Clock generation for digital systems requiring precise timing
• Microcontroller and processor clock sources
• Test and measurement equipment requiring stable frequency references
• Communication interfaces needing specific baud rate clocks

Procurement Notes

Verify the specific suffix 'M' indicates the 300-mil DIP package variant. Confirm that the '-100' suffix corresponds to the 100.000 MHz maximum operating frequency option. Check for end-of-life status as older Maxim Integrated components may have limited availability. Ensure programming hardware compatibility if field reprogramming is required.

Selection Notes

Select this model when a fixed frequency near 100 MHz is needed without external resonators. The DS1075M-100 allows factory programming or on-site programming via the 1-Wire interface. Consider the 8-pin DIP form factor for through-hole designs. Evaluate power consumption requirements, noting the standby current is less than 1 µA in power-down mode.

Part Context

The DS1075 series belongs to the EconOscillator/Divider family. The 'M' suffix denotes the 300-mil DIP package, while other suffixes like 'Z' indicate SOIC packages. The numeric suffix (e.g., -100, -80, -66) specifies the maximum operating frequency capability of the master oscillator. This part is designed to replace discrete oscillator circuits with a single integrated solution.

Replacement Considerations

Direct pin-compatible replacements include other DS1075 variants such as DS1075-80 or DS1075-66, provided the frequency requirement is met. Cross-reference with DS1070 series for similar functionality in different packages. Verify that any substitute supports the same 5V supply and DIP packaging constraints.
