LOW SKEW 1 TO 4 CLOCK BUFFER
DATASHEET
ICS553
Description
The ICS553 is a low skew, single input to four output,
clock buffer. Part of IDT’s ClockBlocksTM family, this is
our lowest skew, small clock buffer.
See the ICS552-02 for a 1 to 8 low skew buffer. For
more than eight outputs, see the MK74CBxxx
BuffaloTM series of clock drivers.
IDT makes many non-PLL and PLL based low skew
output devices as well as Zero Delay Buffers to
synchronize clocks. Contact us for all of your clocking
needs.
