CY2DP818ZI

Overview

The CY2DP818ZI is a fanout buffer manufactured by Cypress Semiconductor Corp, designed for clock distribution applications. It features a single circuit with a 1:8 input-to-output ratio and supports differential signaling on both input and output sides. The device operates at a maximum frequency of 350 MHz and requires a supply voltage between 3.135V and 3.465V. Input signal compatibility includes LVDS, LVPECL, and LVTTL, while the outputs provide LVPECL signals. It is housed in a 38-TSSOP package and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• 1:8 Fanout Buffer (Distribution) with differential input/output support
• Maximum operating frequency of 350 MHz
• Input compatibility with LVDS, LVPECL, and LVTTL standards
• LVPECL output signaling

Applications

Procurement Notes

Verify the specific ordering suffix against official Cypress documentation to confirm pinout and electrical characteristics. Ensure the 38-TSSOP package dimensions align with PCB layout requirements. Confirm that the 3.135V to 3.465V supply voltage range matches the system power design. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 1:8 split is required from LVDS, LVPECL, or LVTTL inputs to LVPECL outputs. Ensure the system can accommodate the 350 MHz maximum frequency and the specified 3.135V-3.465V supply voltage. Verify that the 38-TSSOP surface mount package fits the mechanical constraints. Consider thermal performance within the -40°C to 85°C operating range.
