CLOCK SLICER USER CONFIGURABLE PECL OUTPUT ZDB
IDT™ / ICS™ CLOCK SLICER USER CONFIGURABLE PECL OUTPUT ZDB 1
Description
The ICS527-03 is the most flexible way to generate an
output clock from an input clock with zero skew. The
user can easily configure the device to produce nearly
any output clock that is multiplied or divided from the
input clock. The part supports non-integer
multiplications and divisions. Using Phase-Locked
Loop (PLL) techniques, the device accepts an input
clock up to 200 MHz and produces an output clock up
to 160 MHz.
The ICS527-03 aligns rising edges on CLKIN with
FBPECL at a ratio determined by the reference and
feedback dividers.
For a PECL input and output clock with zero delay, use
the ICS527-04.
