Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer origin, noting that Cypress Semiconductor has been acquired by Infineon Technologies. Confirm the specific suffix 'ZXC-20' matches the required 18.432MHz specification and 3.3V operation. Ensure the package type is strictly 16-TSSOP. Check RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference the base part number CY26049 to ensure functional compatibility with system requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a dedicated clock generator is needed for 3.3V logic systems. The choice depends on the requirement for a single-channel frequency synthesizer with a 16-pin surface-mount footprint. Consider the 18.432MHz input constraint during design. Compare against other CY26049 variants like the ZXC-36 only if different frequency outputs are required. Ensure the TSSOP package fits the PCB layout constraints.
