IDT49FCT3805BPYI

Clock Buffers, Drivers Overview

The IDT49FCT3805BPYI is a dual 1-to-5 clock driver manufactured by Renesas Electronics. It utilizes advanced CMOS technology to provide two independent banks of drivers, each with a 1:5 fanout ratio and individual output enable controls. The device operates on a single 3.3V supply voltage (3.0V to 3.6V) and features low capacitance inputs with hysteresis for high-speed signal integrity. A dedicated 'heartbeat' monitor output allows for diagnostics and PLL driving, replicating the input signal characteristics. Designed for applications requiring critical skew control and high signal quality in address distribution or clock networks.
