49FCT3805PYGI

Overview

The Renesas 49FCT3805PYGI is a dual 1-to-5 clock driver built using advanced CMOS technology, designed for high-speed clock distribution where signal quality and skew are critical. It operates at 3.3V with LVCMOS input and output types. The device features two independent driver banks, each providing a 1:5 fanout with individual output enable control. It includes a 'heartbeat' monitor output identical to other outputs for diagnostics and PLL driving. The component supports low capacitance inputs and allows single point-to-point transmission line driving.

Feature Summary

• Dual 1-to-5 clock driver configuration with independent output enables
• Heartbeat monitor output for diagnostics and PLL driving
• Low capacitance inputs for high-speed performance
• LVCMOS compatible input and output signaling

Applications

• High-speed clock distribution systems requiring low skew
• Address distribution in point-to-point transmission lines
• PLL driving applications
• Diagnostics monitoring via heartbeat output

Part Context

The 49FCT3805PYGI belongs to the FCT3805 family of 3.3V clock drivers. It is functionally equivalent to variants such as the 49FCT3805QGI and 49FCT3805APYGI, differing primarily in package type (SSOP-20) and specific suffix designations. The core functionality remains consistent across the series, offering dual 1:5 fanout capabilities.

Replacement Considerations
