49FCT3805BQGI

Overview

The Renesas 49FCT3805BQGI is a dual 1:5 non-inverting clock driver built using advanced dual metal CMOS technology. Operating at 3.3V, the device features two independent driver banks, each providing five outputs with individual output enable controls. It incorporates a 'heartbeat' monitor for diagnostics and PLL driving, where the MON output mirrors standard output specifications. Designed for high-speed clock distribution, it ensures low skew and high signal quality, supporting single point-to-point transmission line driving for applications like address distribution.

Feature Summary

• Dual 1:5 fanout configuration with independent output enable control per bank
• Integrated 'heartbeat' monitor output for diagnostics and PLL driving
• Low capacitance inputs with hysteresis for improved signal integrity
• Advanced dual metal CMOS technology optimized for 3.3V operation

Applications

• High-speed clock distribution systems requiring low skew
• Address distribution networks with multiple receivers
• Single point-to-point transmission line driving
• PLL driving circuits with diagnostic monitoring

Part Context

The 49FCT3805BQGI belongs to the FCT3805 family of clock drivers. The 'B' suffix typically denotes specific electrical or packaging variations within this series, while 'QGI' indicates automotive-grade qualification and a QSOP-20 package. This component serves as a buffer/driver in the broader 49FCT product line, distinct from synthesizers like the 8T49N series.
