The ICS541 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
135 MHz at 3.3 V, and by using proprietary Phase
Locked Loop (PLL) techniques, produces a divide
by 1, 2, 4, or 8 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 an 80 MHz
input clock is used, the ICS541 can produce low
skew 80 MHz and 40 MHz clocks, or 40 MHz
and 20 MHz clocks, or 20 MHz and 10MHz
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 ICS541 is a member of the ICS
ClockBlocks family of clock building blocks.
See the ICS542 and ICS543 for other clock
dividers, and the ICS300, 501, 502, and 503 for
clock multipliers.
