1:5 fanout per bank
"Heartbeat" monitor output
V
CC
= 3.3V ± 0.3V
Available in SSOP and QSOP packages
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 outputs
and 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 FCT3805 also allows single point-to-point
transmission line driving in applications such as address distribution, where one
signal must be distributed to multiple recievers with low skew and high signal
quality.
For more information on using the FCT3805 with two different input
frequencies on bank A and B, please see AN-236.
