DS1094LU-42M+T

Clock Generators, PLLs, Frequency Synthesizers Overview

The DS1094LU-42M+T is a silicon oscillator generating four multiphase, spread-spectrum square-wave outputs. It operates on a 3.0V to 3.6V supply with an active current of 1.4mA to 3mA. The device supports output frequencies from 2MHz down to 31.25kHz via internal prescaling. Dithering options include 0%, 2%, 4%, or 8% to reduce electromagnetic interference. Configuration is managed through an I2C-compatible 2-wire serial interface, storing settings in nonvolatile memory.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates four multiphase outputs (two, three, or four-phase modes)
• Spread-spectrum dithering reduces peak spectral energy and EMI
• I2C-compatible 2-wire serial interface for programmable frequency and phase
• Nonvolatile configuration storage eliminates external timing components

Clock Generators, PLLs, Frequency Synthesizers Applications

• Switch-mode power supplies

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging versus standard tube packaging. Confirm the '42M' designation corresponds to the factory-programmed output frequency. Check current availability status as distribution channels may vary for this specific variant.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency, multiphase clock source is required for DC-DC converters. Ensure the system requires the specific factory-programmed frequency associated with the '42M' suffix. Verify that the 8-pin µSOP package fits the PCB layout constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the DS1094L EconOscillator family, which provides silicon-based clock generation solutions. The device replaces discrete crystal and oscillator circuits by integrating the master oscillator, prescaler, and phase generator into a single chip.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the DS1094L series. Verify that any substitute maintains the same voltage range, package type, and I2C interface compatibility.
