frequencies. Their differential characteristic supports
the transmission of high-speed data patterns without
the negative effects of electromagnetic interference
(EMI). All MAX5888 LVDS inputs feature on-chip termi-
nation with differential 100
resistors. See Figure 6 for
a simplified block diagram of the LVDS inputs.
A common-mode level of 1.25V and an 800mV differen-
tial input swing can be applied to these inputs.
Segment Shuffling (SEL0)
Segment shuffling can improve the SFDR of the
MAX5888. The improvement is most pronounced at
higher output frequencies and amplitudes. Note that an
improvement in SFDR can only be achieved at the cost
of a slight increase in the DAC
’
s noise floor.
Pin SEL0 controls the segment-shuffling function. If
SEL0 is pulled low, the segment-shuffling function of
the DAC is disabled. SEL0 can also be left open,
because an internal pulldown resistor helps to deacti-
vate the segment-shuffling feature. To activate the
MAX5888 segment-shuffling function, SEL0 must be
pulled high.
Power-Down Operation (PD)
The MAX5888 also features an active-high power-down
mode, which allows the user to cut the DAC
’
s digital
current consumption to less than 6μA and the analog
current consumption to less than 0.3mA. A single pin
(PD) is used to control the power-down mode (PD = 1)
or reactivate the DAC (PD = 0) after power-down.
Enabling the power-down mode of the MAX5888 allows
the overall power consumption to be reduced to less
than 1mW. The MAX5888 requires 10ms to wake up
from power-down and enter a fully operational state.
Applications Information
Differential Coupling Using a
Wideband RF Transformer
The differential voltage existing between IOUTP and
IOUTN can also be converted to a single-ended volt-
age using a transformer (Figure 7) or a differential
amplifier configuration. Using a differential transformer
coupled output, in which the output power is limited to
0dBm, can optimize the dynamic performance.
However, make sure to pay close attention to the trans-
former core saturation characteristics when selecting a
transformer for the MAX5888. Transformer core satura-
tion can introduce strong 2nd-harmonic distortion,
especially at low output frequencies and high signal
