Description
The ICS542 is 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 at 3.3 V 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.
For instance, if an 100 MHz input 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.
See the ICS541 and ICS543 for other clock dividers, and
the ICS501, 502, 511, 512, and 525 for clock multipliers.
