49FCT3805EPYGI8 - Renesas Electronics

Description: The FCT3805 is a 3.3 volt clock driver built using advanced CMOS technology. The device consists of two banks of drivers, each with a 1:5 fanout and its own output enable control. The device has a "heartbeat" monitor for diagnostics and PLL driving. The MON output is identical to all other outputsand complies with the output specifications in this document. The FCT3805 offers low capacitance inputs.The FCT3805 is designed for high speed clock distribution where signal quality and skew are critical. The FCT3
