49FCT3805EQGI8

Overview

The 49FCT3805EQGI8 is a dual clock fanout buffer manufactured by Renesas Electronics Corporation. It features two independent driver banks, each providing a 1:5 input-to-output ratio. The device operates on a single supply voltage ranging from 3V to 3.6V and supports CMOS and LVTTL logic levels for both inputs and outputs. Packaged in a 20-SSOP (0.154" width) surface-mount enclosure, it functions within an industrial temperature range of -40°C to +85°C. Designed for high-speed applications, the component ensures low skew and signal integrity for critical clock distribution networks.

Feature Summary

• Dual independent driver banks with individual output enable controls
• Heartbeat monitor output for diagnostic verification and PLL driving
• Low capacitance inputs designed for high-speed signal quality
• Supports single point-to-point transmission line driving

Applications

• High-speed clock distribution systems requiring low skew
• Address distribution where one signal drives multiple receivers
• PLL driving applications utilizing heartbeat monitoring
• Critical signal integrity network routing

Procurement Notes

Verify the specific suffix 'EQ' against official Renesas documentation to confirm package dimensions and electrical characteristics match project requirements. Ensure compatibility with 3V to 3.6V supply rails and LVTTL/CMOS interface standards. Confirm lead-free status and RoHS compliance through current datasheets before finalizing procurement specifications.

Selection Notes

Select this component when dual independent 1:5 clock buffering is required with integrated diagnostic capabilities. The inclusion of a heartbeat monitor distinguishes it from standard buffers, offering direct feedback for system health. It is suitable for designs prioritizing signal quality and minimal skew over simple fanout expansion.

Part Context

This part belongs to the 49FCT series of high-performance clock drivers built using advanced dual metal CMOS technology. It serves as a specialized solution for distributing clock signals across complex digital systems while maintaining precise timing relationships between source and destination nodes.
