PY2071ASC-101

Programmable Timers And Oscillators Overview

The CY2071A is a single-PLL general-purpose EPROM programmable clock generator manufactured by Cypress Semiconductor Corp. It features a single phase-locked loop architecture with up to three configurable outputs, designed for low skew, low jitter, and high-accuracy timing applications. The device supports configurable 5V or 3.3V operation and includes an internal loop filter. Input frequency ranges include 10 MHz–25 MHz for external crystals and 1 MHz–30 MHz for reference clocks. It is housed in an 8-pin 150-mil SOIC package.

Programmable Timers And Oscillators Feature Summary

• Single phase-locked loop architecture

• Up to three configurable outputs
• Configurable 5V or 3.3V operation

Programmable Timers And Oscillators Applications

• Generating custom frequencies from external sources
• Meeting critical industry standard timing requirements
• Supporting low-power applications

Programmable Timers And Oscillators Procurement Notes

Verify the exact suffix of the part number against official Cypress documentation to confirm voltage levels and programming type. Factory-programmable variants (e.g., CY2071A) differ from field-programmable ones (e.g., CY2071AF). Ensure the input source matches the specified crystal or reference clock range.

Programmable Timers And Oscillators Selection Notes

Select based on required output count and voltage compatibility. Choose factory-programmable versions for fixed designs or field-programmable versions for flexibility. Verify input frequency constraints: 10–25 MHz for crystals or 1–30 MHz for reference clocks. Ensure the 8-pin SOIC package fits the board layout.

Programmable Timers And Oscillators Part Context

The CY2071A belongs to Cypress's family of programmable clock generators. It serves as a replacement for discrete oscillator solutions, reducing component count. Variants like CY2071AI offer industrial temperature ranges, while AF/AFI allow field programming.
