The Si534xH coherent optical clock family replaces discrete timing solutions that rely on large footprint voltage controlled SAW oscillators (VCSOs) to provide low-jitter reference timing for data converters. Unlike VCSOs that support single, fixed frequencies, the Si534xH clocks support frequencies of up to 2.7GHz without the need to change components.
The Si5344H and Si5342H clocks combine frequency flexibility with jitter performance of 50fs RMS. With a jitter attenuating PLL, high-frequency output drivers, fractional frequency synthesis and digitally controlled oscillator technology, the Si534xH family is said to provide all the clocking functions required for coherent optical transceiver applications while enabling 40% smaller footprint and 40% lower power than competing solutions.
