CY25404ZXI012T

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY25404ZXI012T is a quad PLL programmable clock generator with spread spectrum capability, housed in a 20-pin TSSOP package. It supports an input frequency range of 8 to 48 MHz for crystals and 8 to 166 MHz for external clocks. The device generates up to nine clock outputs within a frequency range of 3 to 166 MHz (or 3 to 50 MHz at 1.8 V). It operates on a VDD supply voltage between 2.25 V and 3.60 V, while output banks support 1.71 V to 3.60 V. Cycle-to-cycle jitter is typically 100 ps or less. The component is rated for industrial temperature ranges from -40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration associated with the suffix '012' against official Infineon documentation before procurement. Confirm that the required operating temperature range aligns with the Industrial grade designation indicated by the 'I' in the part number. Ensure compatibility with the 20-pin TSSOP footprint during board layout planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple independent clock frequencies are required from a single crystal or reference input. Verify that the target application requires glitch-free switching capabilities and programmable drive strength settings. Ensure the design accommodates separate power supplies for the three output banks if different voltage levels are needed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the CY25404 family of quad PLL programmable clock generators. The 'ZXI' designation indicates the 20-pin TSSOP package and Industrial temperature rating.
