MAX5898
16-Bit, 500Msps, Interpolating and Modulating
Dual DAC with Interleaved LVDS Inputs
12
______________________________________________________________________________________
Detailed Description
The MAX5898 dual, 500Msps, high-speed, 16-bit, cur-
rent-output DAC provides superior performance in com-
munication systems requiring low-distortion analog-signal
reconstruction. The MAX5898 combines two DAC cores
with 8x/4x/2x programmable digital interpolation filters, a
digital quadrature modulator, an SPI-compatible serial
interface for programming the device, and an on-chip
1.2V reference. Individual DAC channel gain and offset
adjustments are available to compensate for downstream
signal-path imbalances. The full-scale output current
range is adjustable from 2mA to 20mA to optimize power
dissipation and gain control.
Each channel contains three selectable interpolating fil-
ters making the MAX5898 capable of 2x, 4x, 8x, or no
interpolation, which allows for low input data rates and
high DAC update rates. When operating in 8x interpola-
tion mode, the interpolator increases the DAC conversion
rate by a factor of eight, providing an eight-fold increase
in separation between the reconstructed waveform spec-
trum and its first image. The MAX5898 accepts either
two’s complement or offset binary input data format on a
single interleaved LVDS input bus.
The MAX5898 includes modulation modes at fIM / 2 and
fIM / 4, where fIM is the data rate at the input of the mod-
ulator. If 2x interpolation is used, this data rate is 2x the
input data rate. If 4x or 8x interpolation is used, this data
rate is 4x the input data rate. Table 1 summarizes the
modulator operating data rates.
The power-down modes can be used to turn off each
DAC’s output current or the entire digital section.
Programming both DACs into power-down simultane-
ously powers down the digital interpolation filters. Note
that the SPI section is always active.
The analog and digital sections of the MAX5898 have
separate power-supply inputs (AVDD3.3, AVDD1.8,
