CLOCK SLICER USER CONFIGURABLE PECL INPUT ZERO DELAY BUFFER
IDT™ / ICS™ CLOCK SLICER USER CONFIGURABLE PECL INPUT ZERO DELAY BUFFER 1
Description
The ICS527-02 Clock Slicer is the most flexible way to
generate a CMOS output clock from a PECL 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. A
SYNC pulse indicates when the rising clock edges are
aligned with zero skew. 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 ICS527-02 aligns rising edges on PECLIN with
FBIN at a ratio determined by the reference and
feedback dividers.
For a PECL input and output clock with zero delay, use
the ICS527-04.
For a CMOS input and PECL output with zero delay,
use the ICS527-03.
