CY2DP818ZXC

Overview

The CY2DP818ZXC is a fanout buffer manufactured by Cypress Semiconductor Corp, designed for clock distribution applications. It features a 1:8 input-to-output ratio and supports differential LVDS, LVPECL, and LVTTL inputs with LVPECL outputs. The device operates at a maximum frequency of 350 MHz within a supply voltage range of 3.135V to 3.465V. Packaged in a 38-TSSOP (38-TFSOP) surface-mount case, it functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• 1:8 Fanout Buffer Configuration
• Supports LVDS, LVPECL, and LVTTL Inputs
• LVPECL Output Standard
• 350 MHz Maximum Frequency

Applications

• Clock Distribution Networks
• High-Speed Digital Systems
• Telecommunications Equipment

Procurement Notes

Verify the specific package variant against the 38-TFSOP specification. Confirm that the required input signal standards (LVDS, LVPECL, or LVTTL) align with the system design. Ensure the operating environment remains within the 0°C to 70°C temperature range and the power supply stays between 3.135V and 3.465V for proper functionality.

Selection Notes

Select this component when a single differential or single-ended clock source needs to drive eight LVPECL loads. Verify compatibility with the available input formats (LVDS, LVPECL, LVTTL). Ensure the PCB layout accommodates the 38-TSSOP footprint and that the thermal conditions support the commercial temperature grade.

Part Context

This part belongs to the Cypress clock buffer family, specifically engineered for high-speed signal integrity. It serves as a critical interface for distributing reference clocks in complex digital architectures where multiple synchronized outputs are required from a single source.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that match the 1:8 ratio and 350 MHz speed. Verify if other packages like TQFP are available for similar performance requirements.
