SiTime SiT92 Ultra Low Jitter Buffers
SiTime SiT92 Ultra-Low Jitter Buffers is a portfolio of high-performance clock buffers featuring up to 2.1GHz output frequency. The SiTime SiT92 features ultra-low output-to-output jitter, low additive jitter, minimal propagation delay, and broad voltage compatibility. Additionally, the portfolio introduced an automotive-grade, AEC-Q100-qualified fanout clock buffer with a low additive phase jitter of 50fs RMS. This model supports a glitch-free output enable function, reducing the risk of incorrect output clock cycles during activation or deactivation.
