Description

The 621 is a low skew, single input to four output, clock buffer. The device operates from a single 1.2 to 1.8 volt supply and has a 3.3 volt tolerant input, making it ideal for level translation. 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.
