CY22393ZXC-F11KN

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22393ZXC-F11KN is a three-PLL serial-programmable and flash-programmable clock generator manufactured by Cypress Semiconductor. It integrates three phase-locked loops with ultra-wide divide counters (8-bit Q, 11-bit P, and 7-bit post divide) to generate low-jitter, high-accuracy outputs. The device supports I2C serial interface for in-system configurability and features configurable crystal drive strength and frequency select via external LVTTL inputs. It operates at 3.3V and is housed in a 16-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix F11KN against official Cypress/Infineon documentation to confirm pinout and electrical characteristics. Check current lifecycle status as Cypress semiconductor assets are managed by Infineon Technologies. Ensure compatibility with existing I2C programming infrastructure if in-system reconfiguration is required.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple independent clock domains are needed from a single crystal source. The three-PLL architecture allows simultaneous generation of different frequencies. Verify that the required output voltage levels (CMOS/LVPECL) match the target loads, noting that specific LVPECL capabilities may vary by sub-model within the CY22393 family.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY22393 series of universal programmable clock generators. The series is characterized by its dual programmability (flash and serial) and support for CyClocksRT software. It serves as a replacement for fixed-frequency oscillators in designs requiring flexibility or reduced BOM count.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY22393 variants such as CY22393FC or CY22393FCT. Cross-reference pinouts and output buffer configurations carefully, as differences between FC, FX, and ZXC suffixes may affect electrical performance and package dimensions.
