49FCT20805QGI8

Overview

The 49FCT20805QGI8 is a dual 1:5 clock driver manufactured by Renesas Electronics. It operates on a single 2.5V supply voltage, with a specified range of 2.3V to 2.7V. The device supports maximum output frequencies up to 166 MHz and features CMOS or LVTTL outputs. Packaged in a 20-lead QSOP (0.154 inch width), it is designed for high-speed clock distribution applications requiring low skew and signal integrity.

Feature Summary

Dual 1:5 fanout clock driver architecture
2.5V nominal supply voltage operation
Maximum frequency capability of 166 MHz
CMOS/LVTTL compatible output levels

Applications

High-speed clock distribution networks
Address bus distribution systems
Point-to-point transmission line driving

Part Context

This component belongs to the 49FCT family of FCT-compatible clock drivers. While the specific QGI8 suffix denotes the QSOP package and tape-and-reel quantity, the core electrical characteristics align with the standard 49FCT20805 series specifications provided in public documentation.

Replacement Considerations

Public data identifies the 5PB1106PGGI as a manufacturer-recommended replacement for the 49FCT20805 series. Verification of pin compatibility and electrical parameters against the specific QGI8 variant is required before substitution.
