DS1077Z-133+

Overview

The DS1077Z-133+ is a dual-output, programmable fixed-frequency oscillator from the EconOscillator family. It operates on a single 5V supply and requires no external components. The device generates two synchronous outputs with frequencies ranging from 8.1kHz to 133MHz. It features a 2-wire serial interface for on-the-fly frequency programming and stores settings in nonvolatile EEPROM memory. Key electrical parameters include a 4.75V to 5.25V supply voltage range, ±0.5% initial tolerance, and operation within a -40°C to +85°C temperature range.

Feature Summary

• Dual low-jitter, synchronous fixed-frequency outputs (OUT0 and OUT1)
• Frequency range of 8.1kHz to 133MHz with ±0.5% initial tolerance
• Nonvolatile EEPROM storage for frequency settings and control registers
• 2-wire serial interface supporting standard (100kHz) and fast (400kHz) modes

Applications

• Processor-controlled frequency synthesizers
• Standalone clock generation for microcontrollers
• System clock distribution requiring minimal board area

Procurement Notes

Verify the specific ordering suffix 'Z' corresponds to the 8-pin 150mil SO package as defined in the manufacturer's documentation. Confirm that the '+T&R' suffix indicates tape and reel packaging if required for automated assembly, noting that the base datasheet primarily references the tube-packaged part number structure.

Selection Notes

Select this model when a fixed master frequency near 133.333MHz is required. Ensure the application utilizes a 5V power supply, as the device does not support lower voltages like 3.3V. Consider the 8-pin SO package dimensions for PCB layout constraints and verify that the 2-wire interface pins are available on the controlling processor.

Part Context

This component belongs to the DS1077 series of EconOscillators, which includes variants such as the DS1077Z-120 and DS1077Z-100. These parts share identical pinouts and functional architectures but differ in their factory-trimmed master oscillator frequencies. The 'Z' suffix specifically denotes the 8-pin SOIC package option within this product line.

Replacement Considerations

Direct replacements within the same package and function include other DS1077Z variants with different frequency options, such as DS1077Z-120 or DS1077Z-100, provided the system clock requirements can accommodate the alternative frequencies.
