CLOCK SLICER USER CONFIGURABLE ZERO DELAY BUFFER
IDT™ / ICS™ CLOCK SLICER USER CONFIGURABLE ZERO DELAY BUFFER 1
Description
The ICS527-01 Clock Slicer 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. 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 ICS527-01 aligns rising edges on ICLK and FBIN
at a ratio determined by the reference and feedback
dividers.
For configurable clocks that do not require zero delay,
use the ICS525.
