Functional Description
The ASM2P20805A is a 2.5V 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 ASM2P20805A offers low
capacitance inputs. The ASM2P20805A is designed for
high speed clock distribution where signal quality and skew
are critical. The ASM2P20805A also allows single point-to-
point 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.
