High Performance 2-Output, LVCMOS Automotive Clock Buffer


The SiT92182 is an automotive grade 1 (-40°C to 125°C), AEC-Q100-qualified, high-performance LVCMOS fanout clock buffer with low additive phase jitter of just 50 fs RMS.

This buffer 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.
