Description

The ICS542M 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 ICS542M 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.
