DS1075M-60

Overview

The DS1075M-60 is a fixed-frequency oscillator from the EconOscillator family, manufactured by Analog Devices Inc./Maxim Integrated. It provides a dual fixed frequency output of 60.000 MHz with an initial tolerance of ±0.5% and combined variation over temperature and voltage of ±1%. The device operates on a single 5V supply (4.75V to 5.25V) and features user-programmable on-chip dividers (range 2–513) and prescalers (divide-by-2 or -4). It supports internal clock, external clock, or crystal reference options via dedicated pins. The component includes synchronous output gating, power-down mode, and nonvolatile memory for storing configuration registers.

Feature Summary

• Dual fixed frequency outputs at 60.000 MHz with ±0.5% initial tolerance
• User-programmable on-chip dividers (N=2 to 513) and prescaler (M=2 or 4)
• Supports internal oscillator, external clock, or crystal reference inputs
• Synchronous output enable and power-down modes with low standby current (0.8 µA)

Applications

• System clock generation for microcontrollers and digital logic
• Timing references for communication interfaces requiring stable 60 MHz signals
• Embedded systems needing programmable frequency division without external components

Procurement Notes

Verify package type availability as the DS1075 is offered in 8-pin DIP (DS1075M) and SOIC (DS1075Z) formats. Confirm programming status; devices ship configured for half the maximum operating frequency unless factory-programmed. Check for obsolescence status as older Maxim Integrated parts may have limited long-term supply. Ensure evaluation boards (DS1075K) are available if on-site programming is required.

Selection Notes

Select the DS1075M-60 when a precise 60 MHz clock is needed with minimal external components. Choose this part over variable oscillators if frequency stability is critical and reprogramming is not required post-production. Consider the external reference capability if synchronization with another system clock is necessary. Verify that the load capacitance requirements (15 pF typical) match the PCB trace design.

Part Context

The DS1075 belongs to the EconOscillator series, which integrates oscillator circuits and dividers into a single IC. The 'M' suffix denotes the 300-mil DIP package, while '-60' specifies the 60.000 MHz frequency variant. Other variants include -100 (100 MHz), -80 (80 MHz), and -66 (66.667 MHz). This family allows field programming via a 1-Wire compatible interface before board assembly.

Replacement Considerations

Direct pin-compatible replacements within the same family include DS1075-100, DS1075-80, and DS1075-66, provided the frequency difference is acceptable. For different frequencies, the DS1077 series offers similar functionality but with different package options and potentially different programming interfaces. Verify that any substitute maintains the 5V supply requirement and DIP/SOIC footprint.
