CMOS Clock Buffers

Our CMOS clock buffers are low jitter, non-PLL based fanout buffers offering industry-leading flexibility while delivering best-in-class performance. The devices feature CMOS output buffers with minimal cross-talk and superior supply noise rejection, simplifying low-jitter clock distribution in noisy environments. CMOS clock buffers are available in industrial and automotive grade2 temperature ranges.

Outputs
Up to 12
Additive jitter
150 fs RMS typ
