They are used in applications that demand the highest level 69 fs RMS (Grade P) of integration and jitter performance. All PLL components are integrated on-chip, 71 fs RMS (Grade E) eliminating the risk of noise coupling associated with discrete solutions. Device grades J/K/L/M/E have an integrated reference to save board space, improve sys- 85 fs RMS (integer mode) tem reliability and reduces the effect of acoustic emissions noise caused by temper- 100 fs RMS (fractional mode) ature ramps.

These devices are programmable via a serial interface with in-circuit programmable non-volatile memory (NVM) so they always power up Output frequency range with a known frequency configuration. Programming the Si5395/94/92 is easy with Differential: 100 Hz to 1028 MHz TM Skyworks ClockBuilder Pro software. Factory preprogrammed devices are also LVCMOS: 100 Hz to 250 MHz available.
