Pecl/cmos To Cmos Clock Divider
Manufacturer
Integrated Device Technology
Datasheet
PECL/CMOS TO CMOS CLOCK DRIVER
Description
The ICS558-01 accepts a high speed input of either PECL
or CMOS, integrates a divider of 1, 2, 3, or 4, and provides
four CMOS low skew outputs. The chip also has output
enables so that one, three, or all four outputs can be
tri-stated.
The ICS558-01 is a member of the ICS Clock Blocks™ family
of clock generation, synchronization, and distribution
devices.
