CY22393ZXC-551

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22393ZXC-551 is a three-phase-locked loop (PLL) serial-programmable and flash-programmable clock generator manufactured by Cypress Semiconductor. It operates on a single 3.3V supply and utilizes a 16-pin TSSOP package. The device integrates ultra-wide divide counters, including an 8-bit Q counter, an 11-bit P counter, and a 7-bit post-divider, allowing for flexible frequency synthesis. It supports low jitter and high accuracy outputs with configurable crystal drive strength. The component features power management options such as shutdown, output enable, and suspend modes to optimize energy consumption during operation.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer origin, as Infineon Technologies acquired Cypress Semiconductor. Confirm the specific suffix '551' corresponds to the required frequency configuration and pinout. Check RoHS compliance status against current environmental regulations. Ensure the source provides valid datasheets referencing the CY22393 family specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-chip solution for multiple clock domains is required. The CY22393 series offers flexibility through serial programming and flash storage. Compare input frequency ranges and output voltage levels against system requirements. Consider the TSSOP-16 package constraints for PCB layout and thermal management.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY22393 belongs to the CyClocksRT family of universal programmable clock generators. This series is designed to replace multiple discrete clock oscillators and buffers. The ZXC suffix indicates a specific tape-and-reel packaging variant within the TSSOP-16 form factor. It shares architectural similarities with the CY22394 and CY22395 models.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY22393 variants with different suffixes for temperature range or packaging. Cross-reference with CY22394 if LVPECL outputs are needed. Verify compatibility with existing I2C interfaces and programming tools before substitution.
