ICST ICS554G-01, ICS554G-01T Datasheet
PRELIMINARY INFORMATION
ICS554-01
LOW SKEW 1 TO 4 CLOCK BUFFER PECL IN, PECL OUT
Description
The ICS554-01 is a low skew clock buffer with a single
complimentary PECL input to four PECL outputs. Part
of ICS’ Clock Blocks
PECL clock buffer. For parts which do not require PECL
inputs or outputs, see the ICS553 for a 1 to 4 low skew
buffer, or the ICS552-02 for a 1 to 8 low skew buffer. For
more than 8 outputs see the MK74CBxxx Buffalo
series of clock drivers.
ICS 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.
