DS1077Z-120+

Overview

The DS1077Z-120+ is a dual-output, programmable fixed-frequency oscillator from the EconOscillator family. It operates on a single 5V supply (4.75V to 5.25V) and requires no external components. The device features two synchronous outputs with frequencies derived from a master clock of 120MHz, adjustable via internal prescalers and dividers. Standard frequency options range from 8.1kHz to 133MHz. It includes a 2-wire serial interface for in-circuit programming, with settings stored in nonvolatile EEPROM memory.

Feature Summary

• Dual low-jitter, synchronous fixed frequency outputs
• 2-wire serial interface for on-the-fly frequency changes
• Nonvolatile (NV) frequency settings stored in EEPROM
• Single 5V supply operation with power-down mode

Applications

• Processor-controlled frequency synthesizers
• Standalone oscillators for microcontroller systems
• System clock generation requiring minimal board area

Procurement Notes

Verify the ordering suffix 'Z' corresponds to the 8-pin 150mil SO package. Confirm the frequency option '120' indicates the 120.000MHz master frequency variant. Check for RoHS compliance status as indicated by the '+' suffix in procurement channels.

Selection Notes

Select this model when a 120MHz master clock is required. Ensure the application supports the 4.75V to 5.25V supply voltage range. Consider the 8-pin SO package dimensions if board space is constrained. Verify that the 2-wire serial interface is available in the host system design.

Part Context

The DS1077Z-120+ belongs to the DS1077 EconOscillator/Divider series. The 'Z' suffix denotes the 8-pin SO package option. The '120' suffix specifies the standard frequency option of 120.000MHz master clock. Other variants include 133, 125, 100, and 66 MHz options.

Replacement Considerations

Check for other DS1077x-120 variants with different package options such as the µSOP (U suffix). Verify compatibility with existing serial interface protocols if replacing with similar programmable oscillators.
