LOW SKEW 2 INPUT MUX AND 1 TO 8 CLOCK BUFFER DATASHEET ICS552-02 The ICS552-02 is a low skew, single-input to eightoutput clock buffer. The device offers a dual input with pin select for switching between two clock sources. It is part of IDT’s ClockBlocksTM family. See the ICS553 for a 1 to 4 low skew buffer. For more than 8 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.
