Fref = reference c lock frequency
R = 4 when 140 MHz < Fref ≤ 240 MHz
R = 2 when 70 MHz < Fref ≤ 140 MHz
R = 1 when 35 MHz ≤ Fref ≤ 70 MHz

Descrip
tion
The ext
ernal clock input can be used to create the DAC sample clock. This clock must always
operate in the octave range specified below. It is m ultiplied and divided to create the actual
DAC sample clock.
