Overview
The DS1077LZ-60 is a dual-output, programmable fixed-frequency oscillator from the EconOscillator family. It operates on a single 2.7V to 3.6V supply and requires no external components. The device features a 2-wire serial interface for in-circuit programming of prescalers and dividers, with settings stored in nonvolatile EEPROM. Standard frequency options range from 4.87kHz to 66.666MHz. The DS1077LZ-60 specifically supports a master frequency range of 60.000MHz down to 7.32kHz. It provides two synchronous outputs with low jitter and includes power-down modes for energy efficiency.
Feature Summary
- Dual low-jitter synchronous fixed-frequency outputs
- 2-wire serial interface for on-the-fly frequency adjustment
- Nonvolatile EEPROM storage for frequency settings
- Single 2.7V to 3.6V supply operation
Applications
- Processor-controlled frequency synthesizers
- Standalone clock generation systems
- Portable equipment requiring minimal board area
Procurement Notes
Verify package type Z corresponds to the 8-pin 150mil SO format. Confirm the specific frequency option suffix matches the required master frequency range of 60.000MHz to 7.32kHz. Check for RoHS compliance status as older Maxim Integrated parts may vary. Ensure the design accounts for the 2-wire bus pull-up resistor requirements specified in the datasheet.
Selection Notes
Select this model when a master frequency near 60MHz is required. Compare against DS1077LU-60 if a smaller 118mil µSOP package is preferred. Consider DS1077LZ-66 for frequencies up to 66.666MHz. Verify that the system voltage stays within the 2.7V to 3.6V range. Ensure the application can accommodate the 8-pin SO footprint.
Part Context
The DS1077L series belongs to Maxim Integrated's EconOscillator line, designed to replace traditional crystal oscillators. The 'Z' suffix denotes the standard 8-pin SOIC (150mil) package. This component integrates an internal oscillator, prescalers, and a programmable divider into a single chip, simplifying PCB layout by eliminating external resonators or capacitors.
Replacement Considerations
DS1077LU-60 offers the same electrical specifications in a smaller 118mil µSOP package. Other variants like DS1077LZ-40, DS1077LZ-50, and DS1077LZ-66 provide different master frequency ranges. Direct pin-for-pin replacement is possible within the same package type.
