The MAX5858A can operate in interleave data mode by
setting IDE = 1. In interleave data mode, data for both
DAC channels is written through input port A. Channel
B data is written on the falling edge of the CLK signal
and then channel A data is written on the following ris-
ing edge of the CLK signal. Both DAC outputs (channel
A and B) are updated simultaneously on the next rising
edge of CLK. In interleave data mode, the maximum
input data rate per channel is one-half the rate of nonin-
terleave mode. Interleave data mode is an attractive
feature that lowers digital I/O pin count, reduces digital
ASIC cost and improves system reliability (Figure 7).
Applications Information
Differential-to-Single-Ended Conversion
The MAX5858A exhibits excellent dynamic performance
to synthesize a wide variety of modulation schemes,
including high-order QAM modulation with OFDM.
Figure 8 shows a typical application circuit with output
transformers performing the required differential-to-sin-
gle-ended signal conversion. In this configuration, the
MAX5858A operates in differential mode, which
reduces even-order harmonics, and increases the avail-
able output power.

1. CLKXP AND CLKXN MUST BE PRESENT WHEN PLL IS DISABLED, WITH PLLEN CONNECTED TO GND. THE DIAGRAM SHOWS 4x INTERPOLATION.
2. CLK IS AN OUTPUT WHEN PLL IS DISABLED WITH PLLEN CONNECTED TO GND, OTHERWISE, IT IS AN INPUT.
