49FCT3805AQGI

Overview

The 49FCT3805AQGI is a dual 1-to-5 clock driver manufactured by Renesas Electronics. It operates on a single 3V to 3.6V supply and utilizes advanced CMOS technology for high-speed clock distribution. The device features two independent driver banks, each providing five outputs with individual output enable controls. Designed for applications requiring low skew and high signal quality, it includes a 'heartbeat' monitor output identical to standard outputs for diagnostics and PLL driving. The component is housed in a 20-QSOP package.

Feature Summary

• Dual 1:5 fanout configuration with independent output enables
• Low capacitance inputs for high-speed performance
• Integrated heartbeat monitor (MON) output for diagnostics
• LVCMOS input/output compatibility

Applications

• High-speed clock distribution systems
• Address distribution networks
• Single point-to-point transmission line driving
• PLL driving circuits

Part Context

This component belongs to the 49FCT3805A series of clock drivers. It is functionally equivalent to other suffixes such as 49FCT3805ASOGI8 or 49FCT3805APYGI8, differing primarily in packaging type and manufacturing lot specifications rather than electrical functionality.

Replacement Considerations

Verify pin compatibility with alternative packages like SOIC-20 or SSOP-20 variants within the same family. Ensure the replacement part supports the required 3.3V operation and LVCMOS signaling levels.
