DS1077LZ-40+T&R

Overview

The DS1077LZ-40+T&R is a dual-output, programmable fixed-frequency oscillator manufactured by Analog Devices Inc./Maxim Integrated. 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 memory. It provides two synchronous outputs (OUT0 and OUT1) with frequencies ranging from 4.87kHz to 66.666MHz. The -40 suffix indicates a master frequency of 40.000MHz. It is housed in an 8-pin SOIC package.

Feature Summary

• Dual low-jitter synchronous fixed-frequency outputs
• 2-wire serial interface for on-the-fly frequency changes
• Nonvolatile frequency settings stored in EEPROM
• Single 2.7V to 3.6V supply operation

Applications

• Processor-controlled frequency synthesizers
• Stand-alone solid-state oscillators
• System clock generation requiring minimal board area

Procurement Notes

Verify the specific ordering suffix T&R confirms tape-and-reel packaging. Confirm the Z suffix corresponds to the 150mil SO package. Check current availability status as distribution may vary.

Selection Notes

Select based on required master frequency options: 40MHz, 50MHz, 60MHz, or 66.666MHz. Ensure voltage supply matches the 2.7V-3.6V range. Consider package type (SO vs µSOP) based on board space constraints.

Part Context

This component belongs to the DS1077L EconOscillator/Divider family. The 'Z' denotes the 8-pin 150mil SO package, while 'U' would indicate the 8-pin 118mil µSOP package. The '-40' specifies the 40.000MHz master frequency variant.
