CY22393ZXI-510KN

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22393ZXI-510KN is a programmable clock generator manufactured by Infineon Technologies, formerly Cypress Semiconductor. It features three integrated phase-locked loops (PLLs) and supports flash programmability for configuration storage. The device provides up to three output clocks with a maximum frequency of 166 MHz, derived from an input frequency up to 30 MHz. It operates on a single 3.3V supply voltage within the 3.1V to 3.4V range. The component is housed in a 16-pin TSSOP package and is designed for low jitter applications. Key specifications include a maximum operating temperature of +70°C and a typical power consumption of 100 mA.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the lifecycle status carefully as this part number may be discontinued or obsolete. Confirm that the manufacturer has transitioned from Cypress Semiconductor to Infineon Technologies. Ensure compatibility with existing PCB footprints for the 16-pin TSSOP package. Check for moisture sensitivity levels if long-term storage is involved before reflow soldering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when three independent clock outputs are required from a single source. Verify that the input crystal frequency does not exceed 30 MHz and the desired output frequencies are within the 166 MHz limit. Consider the 3.3V operating voltage requirement and ensure the system power rail stability meets the 3.1V to 3.4V specification. Evaluate if the 400 ps jitter specification meets the signal integrity requirements of the downstream logic.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY22393 series of universal programmable clock generators. The series is characterized by its flexibility in generating various clock frequencies using internal PLLs. The 'ZXI' suffix typically denotes specific packaging and temperature grade variations within the Infineon portfolio. The device replaces older fixed-frequency oscillators in designs requiring frequency agility.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-to-pin replacements within the same family include CY22393ZXI-549. Verify electrical parameters such as max frequency and jitter against the original design requirements.
