The ICS542 is a cost effective way to produce a
high quality clock output divided from a clock
input. The chip accepts a clock input up to
156 MHz, and produces a divide by 2, 4, 6, 8, 12,
or 16 of the input clock. There are two outputs on
the chip, one being a low-skew divide by two of
the other. So, for instance, if a 100 MHz clock is
used, the ICS542 can produce low skew 50 MHz
and 25 MHz clocks, or low skew 25 MHz and
12.5 MHz clocks. The chip has an all-chip power
down mode that stops the outputs low, and an OE
pin that tri-states the outputs.
The ICS542 is a member of the ICS
ClockBlocks family of clock building blocks.
See the ICS541 and ICS543 for other clock
dividers, and the ICS501, 502, 511, 512 and 525
for clock multipliers.
