MAX31D80T-003+

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX31D80T-003+ is a spread-spectrum clock generator from the MAX31C80/MAX31D80 family, designed for automotive applications operating between -40°C and +125°C. It utilizes an internal phase-locked loop to generate a 12MHz output clock from a 12MHz input source. The device provides down-dithered frequency modulation with a factory-programmable dither rate of 25kHz. Powered by a 3.3V supply (range 3.0V to 3.6V), it features low cycle-to-cycle jitter and operates within a compact 10-pin TDFN package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates down-dithered spread-spectrum clocks in the 2MHz to 134MHz range
• Factory-programmed for 12MHz input to 12MHz output conversion with 25kHz dither rate
• Supports crystal or clock inputs ranging from 8MHz to 134MHz
• Low cycle-to-cycle jitter of 75ps typical at 100MHz output

Clock Generators, PLLs, Frequency Synthesizers Applications

• Automotive infotainment systems
• Graphics cards
• Set-top boxes
• Printers

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific '003' suffix configuration against the official Selector Guide to confirm the 12MHz input/output parameters. Confirm the 'T' suffix indicates tape-and-reel packaging. Ensure compatibility with the -40°C to +125°C automotive temperature rating required for the target application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a down-dithered spread-spectrum profile is required to reduce EMI. Compare against the MAX31C80 variant if center-dithering is preferred instead. Verify that the 12MHz factory-programmed frequency matches the system requirements, as custom frequencies require direct factory ordering.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MAX31C80/MAX31D80 series of spread-spectrum clock generators. The MAX31D80 specifically offers down-dithering capabilities, whereas the MAX31C80 provides center-dithering. Both share identical pinouts and package styles but differ in their frequency modulation modes.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MAX31C80T-UGQ+ serves as a functional alternative if center-dithering is acceptable, though it differs in modulation type. Direct replacement requires matching the 12MHz I/O frequency and dither rate specifications found in the Selector Guide.
