The LMK5B33414 employs 6 output multiplexers or muxes to distribute frequency sources to the respective output banks. OUT0 and OUT1 each have a separate 6:1 mux to individually select a source. OUT2 and OUT3 output channels share one 3:1 mux . The output bank OUT4 to OUT7 share one 2:1 mux and a second 2:1 mux is shared across the output bank OUT8 to OUT13.

The 6:1 MUX on OUT0 and OUT1 are the most flexible providing selection among APLL3 post divider, APLL2 post divider, the APLL1 primary post divider, APLL secondary post divider, buffered XO or reference input as a frequency source. The 3:1 MUX feeding the OUT2 and OUT3 can select a source between the APLL3 post divider, APLL2 post divider or the APLL1 primary post divider. OUT4 to OUT7 bank or OUT8 to OUT13 bank can each select a frequency source from the APLL3 post divider or the APLL2 post divider. The two 2:1 muxes for the
