PY2071ASL-648

Programmable Timers And Oscillators Overview

The CY2071ASL-648 is a single-phase-locked loop (PLL) general-purpose EPROM programmable clock generator manufactured by Cypress Semiconductor. It features an internal loop filter and supports up to three configurable outputs with low skew, low jitter, and high accuracy. The device accepts input frequencies of 10 MHz–25 MHz via an external crystal or 1 MHz–30 MHz via a reference clock. It offers configurable 5V or 3.3V operation and includes power management capabilities through an output enable pin.

Programmable Timers And Oscillators Feature Summary

• Single PLL architecture with EPROM programmability for custom frequency generation
• Up to three configurable outputs with low skew and low jitter characteristics
• Internal loop filter eliminates the need for external components
• Supports both factory-programmable and field-programmable options

Programmable Timers And Oscillators Applications

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

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix '648' against official Cypress documentation to confirm exact factory programming parameters. Ensure compatibility with the required input frequency range (10–25 MHz crystal or 1–30 MHz reference). Confirm that the 8-pin SOIC package aligns with board layout constraints. Check for available programming support if field-programmable variants are preferred over factory-programmed units.

Programmable Timers And Oscillators Selection Notes

Select this component when a single device must generate multiple related frequencies from one input source. Choose between factory-programmable (CY2071A/AI) or field-programmable (CY2071AF/AFI) versions based on customization needs. Ensure the input signal matches the specified frequency ranges. Verify that the 8-pin SOIC package fits the design footprint.

Programmable Timers And Oscillators Part Context

The CY2071A series belongs to Cypress's family of general-purpose programmable clock generators. These devices are designed to alleviate the need for multiple discrete timing components. The series supports various packaging options and voltage configurations to integrate easily into standard design platforms.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes within the CY2071A family include CY2071A, CY2071AI, CY2071AF, and CY2071AFI. Selection depends on whether factory or field programmability is required. Verify that any replacement maintains the same output count and voltage configuration.
