sources directly to the device without external resistors
to define the DC level. The input resistance of CLKP
and CLKN is 5k
.
A convenient way to apply a differential signal is with a
balun transformer as shown in Figure 15. Alternatively,
these inputs may be driven from a CMOS-compatible
clock source, however it is recommended to use
sine-wave or AC-coupled differential ECL/PECL drive for
best dynamic performance.
Output Interface (OUTI, OUTQ)
The MAX5893 outputs complementary currents (OUTIP,
OUTIN) and (OUTQP, OUTQN), that can be utilized in a
differential configuration. Load resistors convert these
two output currents into a differential output voltage.
The differential output between OUTIP (OUTQP) and
OUTIN (OUTQN) can be converted to a single-ended
output using a transformer or a differential amplifier.
Figure 16 shows a typical transformer-based applica-
tion circuit for generation of IF output signals. In this
configuration, the MAX5893 operates in differential
mode, which reduces even-order harmonics, and
increases the available output power. Pay close atten-
tion to the transformer core saturation characteristics
when selecting a transformer. Transformer core satura-
tion can introduce strong second harmonic distortion,
especially at low output frequencies and high signal
