DS1077Z-100+T&R

Overview

The DS1077Z-100+T&R 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 features two synchronous outputs (OUT0 and OUT1) with frequencies ranging from 8.1kHz to 133MHz. It includes a 2-wire serial interface for on-the-fly programming of prescalers and dividers, with settings stored in nonvolatile EEPROM memory. Electrical characteristics include a ±0.5% initial tolerance and frequency variation of ±0.5% over the +25°C to +70°C temperature range. The unit is housed in an 8-pin SO package.

Feature Summary

• Dual low-jitter, synchronous fixed-frequency outputs
• 2-wire serial interface for processor control or standalone operation
• Nonvolatile EEPROM storage for frequency settings
• Single 5V supply operation with power-down mode

Applications

• Processor-controlled frequency synthesizers
• Standalone clock generation systems
• In-circuit reprogrammable clock sources

Procurement Notes

Verify the specific suffix 'T&R' indicates tape-and-reel packaging when sourcing. Confirm the 'Z' designation corresponds to the 8-pin 150mil SO package variant. Ensure compatibility with the required 2-wire serial bus voltage levels and check for any lead-free compliance documentation if required by assembly standards.

Selection Notes

Select this model for applications requiring a master frequency up to 100MHz with submultiple output options. The DS1077Z-100 provides a factory-trimmed master clock that can be divided by prescalers P0/P1 (divisors 1, 2, 4, 8) and divider N (2 to 1025). Consider the ±0.5% tolerance limits for precision timing requirements and ensure the 8-pin SO footprint fits the PCB layout constraints.

Part Context

This component belongs to the Maxim Integrated/Analog Devices DS1077 EconOscillator series. The 'Z' suffix denotes the 8-pin 150mil SO package, while the number '100' specifies the standard frequency option range of 100.000MHz down to 12.2kHz. Other variants include the U-suffix for µSOP packages and different numeric codes for distinct master frequencies like 133MHz or 66MHz.

Replacement Considerations

Direct pin-compatible replacements within the same family include DS1077Z-133, DS1077Z-125, DS1077Z-120, and DS1077Z-66, which share identical pinouts and functionality but differ in maximum master frequency specifications.
