AD9854 PRELIMINARY TECHNICAL DATA
_____________________________________________________________________________________________________
increased EVM (error vector magnitude). The inverse
SINC function may be by-passed to significantly
reduce power consumption, especially at higher clock
speeds. When the Q-DAC is configured as a “control”
DAC, the inverse sinc function does not apply.

Inverse sinc is engaged by default and is bypassed by
bringing the “
Bypass Inv Sinc
” bit high in control
register 20 (hex) in the Register Layout Table.

REFCLK Multiplier
– this is a programmable PLL
reference clock multiplier that allows the user to select
an integer clock multiplying value over the range of 4
×
to 20
×
by which the REFCLK input will be multiplied.
Use of this function allows users to input as little as 15
MHz to produce a 300 MHz
system clock.
Five bits in
control register 1E hex set the multiplier value as
follows:
