PY2071ASL-528

Programmable Timers And Oscillators Overview

The CY2071ASXL is a single-PLL general-purpose EPROM programmable clock generator manufactured by Cypress Semiconductor. It features an internal loop filter and supports configurable 5V or 3.3V operation within an 8-pin SOIC package. The device generates up to three configurable outputs with low skew, low jitter, and high accuracy. Input frequency ranges include 10 MHz–25 MHz for external crystals and 1 MHz–30 MHz for reference clocks. Factory-programmable options (CY2071A) and field-programmable options (CY2071AF) are available, providing flexibility for custom frequency generation from external sources while alleviating the need for external components.

Programmable Timers And Oscillators Part Context

The CY2071A series belongs to Cypress's portfolio of general-purpose programmable clock generators. This family includes variants such as CY2071A, CY2071AI, CY2071AF, and CY2071AFI, which differ primarily in their programmability method (factory vs. field) and operating temperature range. These devices are designed to replace multiple discrete clock components, simplifying board design and reducing component count.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the single-PLL architecture and EPROM programmability. Verify input frequency compatibility (10-25 MHz crystal or 1-30 MHz reference) and output configuration needs. Ensure voltage level (3.3V/5V) and package type (8-pin SOIC) alignment. Field-programmable variants (CY2071AF/AFI) may be substituted for factory-programmable ones if reprogramming capability is required.
