CY22395FXI

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22395FXI is a three-PLL serial-programmable flash-programmable clock generator manufactured by Cypress Semiconductor Corp. It features ultra-wide divide counters, including an 8-bit Q counter, an 11-bit P counter, and a 7-bit post-divider. The device supports low jitter and high accuracy outputs with configurable crystal drive strength. It operates at 3.3V and includes power management options such as shutdown, output enable, and suspend modes. The component utilizes an I2C serial interface for in-system configurability and offers digital VCXO capabilities.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Devices utilizing digital VCXO functionality

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY22395FXI belongs to the CY22395 series of clock generators. It shares architectural similarities with the CY22394FXI but differs in output voltage capabilities, supporting 3.3V/2.5V outputs specifically in the CY22395 variant. Both devices utilize the same CyClocksRT software support framework.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The CY22395FXIT is a tape-and-reel version of the CY22395FXI. For applications requiring LVPECL outputs, the CY22394FXI is a related model within the same family, though it lacks the specific 3.3/2.5V output configuration of the CY22395.
