Programmable Timers And Oscillators Procurement Notes

Verify the manufacturer designation carefully, as the part number prefix 'PY' may indicate a specific variant or distributor-specific marking distinct from the standard 'CY' series. Confirm the exact programming status (factory vs. field) and voltage configuration (5V or 3.3V) required for your application. Ensure compatibility with the 8-pin SOIC package dimensions. Cross-reference with official Cypress/Infineon documentation to confirm that the 'PY' prefix does not imply a non-standard or obsolete revision compared to the CY2071A family specifications.

Programmable Timers And Oscillators Selection Notes

Select this component when a single PLL solution is needed to generate multiple related frequencies from one device. Consider the EPROM programmability for easy customization and fast turnaround without external components. Evaluate the input frequency range requirements, noting support for external crystals (10 MHz–25 MHz) or reference clocks (1 MHz–30 MHz). Choose based on the necessary output count and voltage level compatibility. This device alleviates board space constraints through its industry-standard packaging and integrated features.

Programmable Timers And Oscillators Part Context

The PY2071ASC-353 is part of the CY2071A family of single-PLL general-purpose EPROM programmable clock generators. This family is designed to generate custom frequencies from an external source, supporting up to three configurable outputs. The series includes variants like CY2071A, CY2071AI, CY2071AF, and CY2071AFI, differing primarily in programmability options and temperature ranges. These devices are intended to meet critical timing requirements while reducing the need for external components.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes within the same family include CY2071A, CY2071AI, CY2071AF, and CY2071AFI. Verify if the specific 'PY' prefix denotes a unique binning or packaging variation that requires electrical equivalence confirmation. Replacement should maintain the single-PLL architecture and EPROM programmability features unless system design allows for fixed-frequency alternatives.
