CY2PD817ZC

Overview

The CY2PD817ZC is a single-circuit fanout buffer manufactured by Cypress Semiconductor Corp, designed for clock distribution applications. It accepts an LVPECL differential input and provides seven outputs configurable as LVCMOS, LVPECL, or LVTTL. The device supports a maximum operating frequency of 320 MHz and operates within a supply voltage range of 2.375V to 2.625V. It is housed in a 24-TSSOP surface-mount package with a width of 4.40mm and functions reliably across an ambient temperature range of 0°C to 85°C.

Feature Summary

• Single circuit fanout buffer with 1:7 input-to-output ratio
• LVPECL differential input supporting up to 320 MHz operation
• Configurable output levels including LVCMOS, LVPECL, and LVTTL
• Operates on a 2.375V to 2.625V power supply

Applications

• Clock distribution networks requiring signal buffering
• High-speed digital systems utilizing LVPECL inputs
• Interface circuits converting LVPECL to LVCMOS or LVTTL standards

Procurement Notes

Verify the component status is current before procurement. Confirm that the 24-TSSOP package dimensions match the design constraints. Ensure the power supply voltage remains strictly within the 2.375V to 2.625V specification to maintain operational integrity. Check for RoHS compliance requirements if applicable to the target assembly process.

Selection Notes

Select this component when a single LVPECL source must drive multiple loads with varying logic level requirements. The fixed 1:7 ratio limits scalability; ensure the load count does not exceed seven outputs. Verify that the system environment stays within the 0°C to 85°C operating temperature range. Confirm that the 320 MHz frequency limit meets the highest clock speed requirement in the design.

Part Context

This part belongs to the Clock Buffers and Drivers category under Cypress Semiconductor Corp's integrated circuit portfolio. It serves as a specialized timing component distinct from memory or interface controllers found in other product lines. The specific designation identifies it as a high-speed buffer optimized for low-voltage PECL applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative buffers only after verifying pin compatibility and electrical parameter alignment with the original specifications.
