DS1077Z-100+

Overview

The DS1077Z-100+ 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: OUT1 (main) and OUT0 (reference). The standard frequency option for the -100 suffix ranges from 100.000MHz down to 12.2kHz. It includes a 2-wire serial interface for in-circuit programming of prescalers and dividers, with settings stored in nonvolatile EEPROM memory. The unit is housed in an 8-pin SO package.

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
• ±0.5% initial tolerance and ±0.5% variation over temperature (+25°C to +70°C)

Applications

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

Procurement Notes

Verify the specific ordering suffix 'Z' corresponds to the 8-pin 150mil SO package configuration required for the design. Confirm that the standard frequency range of 100.000MHz to 12.2kHz meets the system timing requirements. Ensure the 2-wire serial interface protocol compatibility with the host controller is validated before integration.

Selection Notes

Select this model when a fixed master frequency near 100MHz is required with the ability to divide down to lower frequencies via internal prescalers. The Z suffix indicates surface-mount SO packaging. Consider the U suffix if a smaller 118mil µSOP package is needed instead. Verify power-down current consumption requirements against the standby specifications if energy efficiency is critical.

Part Context

This component belongs to the DS1077 EconOscillator/Divider series by Analog Devices / Maxim Integrated. The 'Z' designation specifically identifies the 8-pin Small Outline (SO) package variant. Other variants include the 'U' for µSOP packages. The '-100' suffix denotes the factory-trimmed master frequency capability starting at 100.000MHz.

Replacement Considerations

DS1077Z-125+ offers a higher master frequency range up to 125.000MHz. DS1077Z-66+ provides a lower master frequency range starting at 66.666MHz. DS1077U-100+ is the same electrical specification but in a smaller µSOP package.
