Functional Description
The ASM2P3805AH is a 3.3V, non-inverting 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 ASM2P3805AH offers
low capacitance inputs.
The ASM2P3805AH is designed for high speed clock
distribution where signal quality and skew are critical. The
ASM2P3805AH
also
allows
transmission line driving in applications such as address
distribution, where one signal must be distributed to
multiple receivers with low skew and high signal quality.
