DS1077LZ-60+

Overview

The DS1077LZ-60+ is a dual-output, programmable fixed-frequency oscillator from the EconOscillator family. It features an internal master oscillator trimmed to 60MHz, with outputs adjustable via prescalers and dividers to frequencies between 4.87kHz and 66.666MHz. The device operates on a single 2.7V to 3.6V supply and includes nonvolatile EEPROM memory for frequency settings. It utilizes a 2-wire serial interface for configuration and supports synchronous output gating.

Feature Summary

• Dual low-jitter synchronous outputs (OUT0 and OUT1) derived from a 60MHz master clock
• Frequency range of 4.87kHz to 66.666MHz with ±0.5% initial tolerance
• Nonvolatile EEPROM storage for frequency and control register settings
• 2-wire serial interface supporting standard (100kHz) and fast (400kHz) modes

Applications

• Processor-controlled frequency synthesizers
• Stand-alone solid-state oscillators
• System clock generation in embedded designs

Procurement Notes

Verify package type Z corresponds to the 8-pin 150mil SO option. Confirm that the suffix '+' indicates RoHS compliance. Check current availability status as this component may be subject to discontinuation or limited stock depending on the distributor.

Selection Notes

Select the DS1077LZ-60+ when a 60MHz master frequency is required. Ensure the application voltage stays within 2.7V to 3.6V. Consider the µSOP package (LU suffix) if board space is constrained, as it offers a smaller 118mil footprint compared to the 150mil SO package.

Part Context

The DS1077L series includes variants with different master frequencies: 40MHz, 50MHz, 60MHz, and 66.666MHz. The 'Z' suffix specifically denotes the 8-pin 150mil SO package, while 'U' denotes the 8-pin 118mil µSOP package. All variants share the same pinout and functional architecture.

Replacement Considerations

Direct replacements include other DS1077Lx models with different master frequencies (e.g., DS1077LZ-50+, DS1077LZ-40+) if the specific 60MHz master clock is not strictly required. Package alternatives exist with the 'U' suffix for µSOP packaging.
