Detailed Description
The MAX5858A dual, high-speed, 10-bit, current-output
DAC provides superior performance in communication
systems requiring low-distortion analog-signal recon-
struction. The MAX5858A combines two DAC cores with
2x/4x programmable digital interpolation filters, a PLL
clock multiplier, divide-by-N clock output, and an on-
chip 1.24V reference. The current outputs of the DACs
can be configured for differential or single-ended opera-
tion. The full-scale output current range is adjustable
from 2mA to 20mA to optimize power dissipation and
gain control.
The MAX5858A accepts an input data rate of up to
165MHz or a DAC conversion rate of up to 300MHz. The
inputs are latched on the rising edge of the clock where-
as the output latches on the following rising edge.
The two-stage digital interpolation filters are program-
mable to 4x, 2x, or no interpolation. When operating in
4x interpolation mode, the interpolator increases the
DAC conversion rate by a factor of four, providing a
four-fold increase in separation between the recon-
structed waveform spectrum and its first image.
The on-chip PLL clock multiplier generates and distrib-
utes all internal, synchronized high-speed clock signals
required by the input data latches, interpolation filters,
and DAC cores. The on-chip PLL includes phase-detec-
tor, VCO, prescalar, and charge-pump circuits. The PLL
can be enabled or disabled through PLLEN.
The analog and digital sections of the MAX5858A have
separate power-supply inputs (AVDD and DVDD). Also,
a separate supply input is provided for the PLL clock
multiplier (PVDD). AVDD, DVDD, and PVDD operate from
a 2.7V to 3.3V single supply.
The MAX5858A features three modes of operation: nor-
mal, standby, and power-down. These modes allow effi-
cient power management. In power-down, the MAX5858A
consumes only 1A of supply current. Wake-up time from
standby mode to normal DAC operation is 0.7s.
Programming the DAC
An 8-bit control word routed through channel A’s data
port programs the gain matching, interpolator configura-
tion, and operational mode of the MAX5858A. The con-
trol word is latched on the falling edge of CW. Table 1
describes the control word format and function.
The gain on channel A can be adjusted to achieve gain
matching between two channels in a user’s system.
The gain on channel A can be adjusted from +0.4dB to
-0.35dB in steps of 0.05dB by using bits G3 to G0 (see
Table 3).
