Description

The 553 is a low skew, single input to four output, clock buffer. Part of Renesas' ClockBlocks™ family, this is our lowest skew, small clock buffer. See the 552-02 for a 1 to 8 low skew buffer. For more than eight outputs, see the MK74CBxxx Buffalo™ series of clock drivers. Renesas makes many non-PLL and PLL based low skew output devices as well as Zero Delay Buffers to synchronize clocks.
