CY25404ZXI014T

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY25404ZXI014T is a quad PLL programmable clock generator with spread spectrum capability, housed in a 20-pin TSSOP package. It supports input frequencies from 8 to 48 MHz via crystal or 8 to 166 MHz via external clock. The device generates up to nine independent output clocks ranging from 3 to 166 MHz (or 3 to 50 MHz at 1.8 V). It features four fully integrated PLLs, selectable VDD supply voltages of 2.5 V, 3.0 V, and 3.3 V, and independent output bank voltages of 1.8 V, 2.5 V, 3.0 V, and 3.3 V. Operating temperature ranges from -40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '014T' against official Infineon/Cypress documentation to confirm factory-programmed configuration details. Ensure the industrial temperature grade (-40°C to +85°C) matches system requirements. Confirm tape and reel packaging specifications if automated assembly is planned. Cross-reference ordering codes to avoid confusion with commercial variants.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple independent clock frequencies are required from a single oscillator source. Verify that the required output voltage levels (1.8V, 2.5V, 3.0V, or 3.3V) align with the target load devices. Consider the spread spectrum feature if EMI compliance is a critical design constraint. Ensure the input frequency range (crystal or external clock) fits the available reference source.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY25404 family of quad PLL clock generators. The 'ZXI' designation indicates the 20-pin TSSOP package and industrial temperature rating. The 'T' suffix typically denotes tape and reel packaging. This series is designed for applications requiring flexible clock distribution with low jitter and programmable EMI mitigation strategies.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Check for direct replacements within the CY25404 family with different temperature grades or packaging options. Verify pin-to-pin compatibility with other Cypress/Infineon clock generators featuring similar PLL counts and output configurations. Ensure functional equivalence regarding spread spectrum capabilities and glitch-free switching requirements.
