ICS542

Clock Divider

Description

Features

• Packaged as 8 pin SOIC

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.

• ICS’ lowest cost clock divider

• Low skew (500ps) outputs. One is ÷ 2 of other.

• Easy to use with other generators and buffers

• Input clock frequency up to 156 MHz

• Output clock duty cycle of 45/55

• Power Down turns off chip

• Output Enable

• Advanced, low power CMOS process

• Operating voltages of 3.0 to 5.5 V

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.
