Production

The SiT92114 is a high-performance LVCMOS fanout clock buffer with low additive phase jitter of 50 fs RMS.

The SiT92114 supports a synchronous glitch-free output enable (OE) function to eliminate potential intermediate incorrect output clock cycles when enabling or disabling outputs. It can operate from a 1.8 V to 3.3 V supply.
