49FCT3805QG

Overview

The Renesas 49FCT3805QGI is a dual 1:5 clock buffer/driver operating at 3.3V, built on advanced CMOS technology. It features two independent driver banks, each providing five outputs with individual output enable controls. Designed for high-speed clock distribution, the device ensures low skew and high signal quality, making it suitable for applications requiring precise timing. The component supports LVCMOS/LVTTL input and output types, operates within a supply voltage range of 3.0V to 3.6V, and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:5 fanout configuration with independent output enables
• Low capacitance inputs for high-speed performance
• Heartbeat monitor output for diagnostics and PLL driving
• LVCMOS/LVTTL compatible input and output levels

Applications

• High-speed clock distribution systems
• Address bus distribution in memory architectures
• Point-to-point transmission line driving
• PLL driving circuits requiring diagnostic monitoring

Part Context

The 49FCT3805Q belongs to the 49FCT series of clock drivers from Renesas Electronics. This series is engineered for applications demanding low skew and high signal integrity. The 'Q' suffix typically denotes specific packaging or qualification standards within the product family, often associated with QSOP-20 packages as seen in related variants like the 49FCT3805QGI8.

Replacement Considerations

Direct replacements include the IDT49F3805QGI and other variants within the 49FCT3805 family such as the 49FCT3805APYGI8 or 49FCT3805ASOGI8, provided pin compatibility and electrical specifications match the design requirements.
