DS1077Z-120+T&R

Overview

The DS1077Z-120+T&R is a dual-output, programmable fixed-frequency oscillator from the EconOscillator family. It generates synchronous clock signals with frequencies ranging from 8.1 kHz to 133 MHz. The device features two independent outputs (OUT0 and OUT1) derived from an internal master oscillator via programmable prescalers and dividers. Frequency settings are stored in nonvolatile EEPROM memory, allowing for on-the-fly reprogramming via a 2-wire serial interface or standalone operation without external components. It operates on a single 5V supply.

Feature Summary

• Dual low-jitter synchronous outputs (OUT0 and OUT1)
• Frequency range of 8.1 kHz to 133 MHz
• Nonvolatile EEPROM storage for frequency settings
• 2-wire serial interface for programmability
• No external components required

Applications

• Processor-controlled frequency synthesizers
• Standalone clock generation for microcontrollers
• System clock distribution in embedded systems

Procurement Notes

Verify the specific ordering suffix 'Z' corresponds to the 8-pin SO package and '+T&R' indicates tape and reel packaging. Confirm that the '-120' designation matches the required 120 MHz maximum frequency option. Ensure compatibility with the 5V supply voltage and 2-wire serial interface requirements of the host system.

Selection Notes

Select this component when a dual-output clock solution with nonvolatile frequency storage is needed. The DS1077Z-120+T&R is suitable for applications requiring frequencies up to 120 MHz. Consider the power-down mode capabilities if energy efficiency is critical. Verify that the 8-pin SO package fits the PCB layout constraints.

Part Context

The DS1077Z-120+T&R belongs to the DS1077 series of EconOscillators. The 'Z' suffix denotes the 8-pin SO package, while 'U' would indicate the µSOP package. The '-120' specifies the standard frequency option range ending at 120 MHz. This part is manufactured by Analog Devices / Maxim Integrated.

Replacement Considerations

Direct replacements within the same family include DS1077Z-133+T&R (up to 133 MHz), DS1077Z-125+T&R (up to 125 MHz), DS1077Z-100+T&R (up to 100 MHz), and DS1077Z-66+T&R (up to 66 MHz). Package variations such as DS1077U-XXX are also pin-compatible alternatives.
