MAX5876/MAX5877/MAX5878 Evaluation Kits
The MAX5876/MAX5877/MAX5878 evaluation kits (EV
kit) are fully assembled and tested printed circuit boards
(PCBs) that contain all the components necessary to
evaluate the performance of the MAX5876/MAX5877/
MAX5878 digital-to-analog converters (DACs). The
MAX5876 (12-bit)/MAX5877 (14-bit)/MAX5878 (16-bit)
are 250Msps, dual DACs with interleaved LVDS inputs,
integrated 1.2V voltage reference, and differential current outputs. The EV kits operate with LVDS-compatible
digital data inputs, a single-ended clock input, and a
3.3V/1.8V dual power supply for simple board operation.
The MAX5876/MAX5877/MAX5878 EV kits also contain
an external 1.25V voltage-reference circuit that can be
used to drive the MAX5876/MAX5877/MAX5878 input
reference voltage pin.

Detailed Description
The MAX5876/MAX5877/MAX5878 EV kits are designed
to simplify the evaluation of the MAX5876/MAX5877/
MAX5878 dual, 12-bit/14-bit/16-bit, 250Msps, currentoutput DACs. The MAX5876/MAX5877/MAX5878 operate
with LVDS-compatible digital data inputs, a differential or
single-ended clock input signal, and two power supplies
(3.3V and 1.8V). The MAX5876/MAX5877/MAX5878
feature internal 1.2V reference voltage.

MAX5876/MAX5877/MAX5878 Evaluation Kits
The MAX5876/MAX5877/MAX5878 EV kits provide header connectors J1 and J2 to interface with a pattern generator, circuitry that converts the differential current
outputs to single-ended voltage signals, and circuitry to
convert a user-supplied single-ended clock signal to a
differential clock signal. The EV kit circuit also includes
an external 1.25V reference source U2 (MAX6161) and
a test point connector that can be used to overdrive the
MAX5876/MAX5877/MAX5878 internal 1.2V bandgap
reference. The EV kit board layout separates the circuit
power into digital, analog, and clock planes to improve
dynamic performance. The input data PC traces are
100Ω differential controlled impedance and the analog
output PC traces are 50Ω controlled impedance.
Power Supplies
The MAX5876/MAX5877/MAX5878 EV kits operate from
a single 1.8V power supply connected to the DVDD1
and AVDD1 input power pads, and a single 3.3V power
supply connected to the DVDD2, AVDD2, and VDD_CK
input power pads for simple operation. However, five
separate power supplies are recommended to optimize
dynamic performance. The EV kit PCB layout is divided
into three sections: digital, analog, and clock. Using separate power supplies for each section reduces noise and
improves the integrity of the analog output signal. When
using separate power supplies, connect a 1.8V power
supply across the DVDD1 and DGND pads and a 3.3V
power supply across DVDD2 and DGND pads (digital).
Connect a 1.8V power supply across the AVDD1 and
AGND pads and a 3.3V power supply across AVDD2
and AGND pads (analog). Connect a 3.3V power supply
across VDD_CK and GND_CK pads (clock).
LVDS Digital Input Data
The MAX5876/MAX5877/MAX5878 EV kits provide two
0.1in, 2 x 20 headers (J1, J2) to interface an LVDS pattern generator to the EV kit. The header data pins are
labeled on the PCB with their appropriate LVDS data bit
designator. Use the labels on the EV kit board to match
the data bits from the pattern generator to the corresponding data pins on headers J1 and J2. The input
data is latched on the rising edge of the clock signal.
The MAX5876/MAX5877/MAX5878 SELIQ and XOR functions can also be controlled by applying an LVDS logic
signal to the J1 header pins labeled SELIQP, SELIQN,
XORP, and XORN. Refer to the LVDS-Compatible Digital
Inputs section in the MAX5876/MAX5877/MAX5878 IC
data sheets for detailed information on the SELIQ and
XOR functions. When using the XOR function, install a
100Ω resistor at the EV kit R14 PCB pad.
4
Clock Signal
The MAX5876/MAX5877/MAX5878 operate with a differential clock input signal. However, the EV kit boards only
require an external single-ended clock signal connected
to the CLK SMA connector. The EV kits feature circuitry
that converts the single-ended clock signal to a differential clock signal. The clock signal can be either a sine or
a square wave. A minimum signal power amplitude of
+8dBm is recommended to drive the clock input. The
MAX5876/MAX5877/MAX5878 accept a clock input frequency in the 2MHz to 500MHz range.
Two’s-Complement/Offset-Binary
Input Format
The two’s-complement or offset-binary input modes of
the MAX5876/MAX5877/MAX5878 are configured with
jumper JU2. Apply either a two’s-complement or offsetbinary formatted input pattern to connectors J1 and J2.
See Table 1 for the jumper JU2 configuration.
Reference Voltage
The MAX5876/MAX5877/MAX5878 require a reference
voltage to set the full-scale output current of the DAC.
The MAX5876/MAX5877/MAX5878 integrate a stable onchip bandgap reference of 1.2V that is selected by
default during initial power-up. An external voltage reference must be connected to test point TP1 when the
internal voltage reference is overdriven. The EV kits circuit also features an on-board, external 1.25V voltage
reference (U2, MAX6161) that can be used to overdrive
the internal bandgap reference. U2 has a tighter voltage-output tolerance and is less susceptible to temperature variations. See Table 2 to select the voltage reference source.
Full-Scale Output Current
The MAX5876/MAX5877/MAX5878 require an external
resistor to set the full-scale output current. The
MAX5876/MAX5877/MAX5878 EV kits full-scale current
are set to 20mA with resistor R7 (2kΩ). Replace resistor
R7 to adjust the full-scale output current. Refer to the
Reference Architecture and Operation section in the
MAX5876/MAX5877/MAX5878 IC data sheets to select
different values for resistor R7.
_______________________________________________________________________________________
MAX5876/MAX5877/MAX5878 Evaluation Kits
To evaluate the converter’s single-ended outputs,
remove transformers T1, T2, and install SMA connectors at the OUTIP, OUTIN, OUTQP, and OUTQN locations. Probe the single-ended signals at the OUTIP and
OUTIN SMA connectors for I-DAC. Probe the singleended signals at the OUTQP and OUTQN SMA connectors for Q-DAC. In a single-ended configuration the
DAC output signal amplitude is equal to 1VP-P at each
of the outputs.
Power-Down Mode
The MAX5876/MAX5877/MAX5878 EV kits powerdown/normal operation mode can be configured with
jumper JU1. See Table 3 for jumper JU1 configuration.
PCB Layout
The MAX5876/MAX5877/MAX5878 EV kits are 4-layer
PCB designs optimized for high-speed signals. All
high-speed digital signal lines are routed through 100Ω
differential impedance-matched transmission lines. All
analog output traces are routed through 50Ω impedance-matched transmission lines. The length of these
100Ω and 50Ω transmission lines is matched to within
40 mils (1mm) to minimize layout-dependent data skew.
The PCB layout separates the digital, analog, and clock
sections of the circuit for optimum performance.

Outputs
The dual-output channels of the MAX5876/MAX5877/
MAX5878 are configured for differential current mode to
achieve the best dynamic performance. The resistor
and transformer networks at the DAC outputs are
designed to convert the differential current signals into
single-ended voltage signals with a 50Ω output impedance. When an LVDS logic-high input signal is applied
to the SELIQP/SELIQN pins, the data on the input bus
(J1 and J2) is loaded into I-DAC and the reconstructed
single-ended signal is available at the OUTPUTI SMA
connector. When an LVDS logic-low input signal is
applied to the SELIQP/SELIQN pins, the data on the
input bus is loaded into Q-DAC and the reconstructed
single-ended signal is available at the OUTPUTQ SMA
connector. When outputs OUTPUTQ and OUTPUTI are
terminated with 50Ω external loads, the full-scale output
signal level is equal to -2dBm.
