DS1065T-80

Overview

The DS1065T-80 is a high-speed clock multiplier and spread spectrum clock generator manufactured by Analog Devices Inc./Maxim Integrated. It operates with a single 3V to 3.6V power supply and features an internal phase-locked loop (PLL) for frequency synthesis. The device accepts crystal or clock inputs and generates LVCMOS outputs, supporting frequencies up to 134MHz. It is housed in an 8-pin uMAX or MSOP package and is designed for applications requiring low jitter and electromagnetic interference reduction through spread spectrum modulation.

Feature Summary

• Integrates a phase-locked loop for stable clock multiplication
• Supports spread spectrum modulation to reduce electromagnetic interference
• Accepts both crystal oscillator and external clock inputs
• Generates LVCMOS output signals suitable for digital logic interfaces

Applications

• Clock generation for microprocessors and memory systems
• Spread spectrum clocking for EMI reduction in digital circuits
• Frequency synthesis for communication interface modules

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm the '-80' designation matches the required output frequency specifications for your design. Check current lifecycle status as older Maxim products may have limited availability or obsolescence notices from Analog Devices.

Selection Notes

Select this component if a compact 8-pin solution is required for clock multiplication. Ensure the input source supports the device's PLL requirements. Verify that the LVCMOS output voltage levels are compatible with the downstream digital loads. Consider thermal dissipation within the small TSSOP or uMAX footprint during operation.

Part Context

This part belongs to the DS1065 series of clock multipliers. It shares functional similarities with the DS1080LU+ but differs in package type and specific frequency characteristics. The series is designed for general-purpose clock generation in embedded systems where space constraints limit the use of larger packages.

Replacement Considerations

The DS1080LU+ is a documented alternative within the same manufacturer portfolio. Verify pin compatibility and output frequency ranges before substitution. Other family members may require different input configurations or offer varying spread spectrum capabilities.
