MAX5858A Evaluation Kit
The MAX5858A evaluation kit (EV kit) is a fully assembled
and tested circuit board that contains all the components
necessary for evaluating the MAX5858A. The MAX5858A
is a dual,10-bit, 300Msps digital-to-analog converter
(DAC) with 4x/2x/1x-configurable interpolation filters. The
MAX5858A also features a phase-locked-loop (PLL) clock
multiplier that generates and distributes all internally synchronized high-speed clock signals required by the input
data latches, interpolation filters, and DAC cores. The EV
kit requires CMOS-compatible data and clock inputs, and
three separate 3V power supplies. The MAX5858A EV kit
can also evaluate the MAX5858 (no PLL) and the 8-bit
MAX5856A (with PLL).

MAX5858A Evaluation Kit
Detailed Description
The MAX5858A EV kit is designed to simplify the evaluation of the MAX5858A 10-bit, dual, 300Msps DAC with
PLL. The board contains all circuitry necessary to evaluate the dynamic performance of this high-speed converter, including circuitry to convert the DAC’s differential output into a single-ended output.
The EV kit provides PC board connector pads for
power supplies AVDDIN, DVDDIN, and PVDDIN. SMA
connectors are included for clock functions CLKIN,
CLKOUT, CLKD, and DAC outputs OUTA and OUTB
connections. The four-layer PC board is a high-speed
design that optimizes the dynamic performance of the
DAC by separating the analog and digital circuitry,
which implements impedance matching for the differential output signal PC board traces. The PC board
traces have been designed for 50Ω impedance.
Power Supplies
The MAX5858A EV kit requires separate analog, digital,
and PLL power supplies. Connect a 3V power supply to
the AVDDIN PC board pad to power the analog portion
of the DAC. Connect the second 3V power supply to the
DVDDIN PC board pad to power the digital portion of
the DAC. Connect the third 3V power supply to the PVDDIN PC board pad to power the PLL portion of the DAC.
Digital Inputs
The MAX5858A EV kit provides connector J1 for the
two 10-bit input data buses. Data bits DA9 through DA2
of channel A share a dual function for data and control
word. The control word is latched by the CW bit (J1-1).
The control word is latched on the falling edge of CW.
Refer to the MAX5858A data sheet for a detailed
description of the control and data word functions. The
data word is latched on the rising edge of the CLK output, pin 20 of the MAX5858A.
DAC Output
The MAX5858A EV kit is designed to provide two pairs
of analog outputs. The outputs can be configured for
either differential or single-ended mode of operation. In
differential mode and with transformer-coupled output
and 50Ω external termination, the MAX5858A delivers a
-2dBm output signal. In single-ended mode, the output
amplitude is 1VP-P at both positive and negative DAC
outputs. To configure the MAX5858A for single-ended
output operation, remove jumpers JU6–JU9, and measure the outputs at the A+, A-, and B+, B- 2-pin headers. To configure the MAX5858A for differential output
operation, install shunts on jumpers JU6–JU9, and
measure the outputs at the OUTA and OUTB SMA con-

Output DC Offset
The MAX5858A EV kit features an option to add a DC
offset to the analog output signals. To add a DC offset,
remove jumper JU2 and connect an appropriate DC
source across jumper JU2. The DC source has to be
able to sink at least 40mA of DC current. The DC offset
must be within 0 to 1.25V.
Interleaved Data Mode
The MAX5858A, MAX5858, and MAX5856A feature an
interleaved data mode that multiplexes the data inputs
of both channels through port A. This feature allows the
user to reduce the bit width of the input data bus. In
interleaved data mode, channel B data is latched on
the falling edge of the clock (CLK), and channel A data
is latched on the following rising edge of the clock
(CLK). Jumper JU3 sets the interleaved data mode
option. Table 4 lists the jumper selection.

Reference Voltage Options
The MAX5858A EV kit supports both internal and external reference configurations. The internal reference
voltage can be accessed at the REFO pad. The EV kit
also accepts an external reference voltage at the REFO
pad to set the full-scale analog-output signal level.
Jumper JU5 selects the reference voltage options for
the EV kit. Table 5 lists the jumper selection.
Evaluating the MAX5858
The MAX5858A EV kit also evaluates the pin-compatible
MAX5858. Refer to the MAX5858 data sheet for more
details on the MAX5858 functions. To evaluate the
MAX5858, replace U1 with the MAX5858 and install a
shunt on jumper JU4.
Evaluating the MAX5856A
The MAX5858A EV kit also evaluates the MAX5856A.
Refer to the MAX5856A data sheet for more details on
the MAX5856A functions. To evaluate the MAX5856A,
the following component changes on the MAX5858A
EV kit are necessary:
•
•
•
•
•
•
Replace U1 with the MAX5856A.
Install a shunt on J1-3 and J1-4.
Install a shunt on J1-5 and J1-6.
Install a shunt on J1-23 and J1-24.
Install a shunt on J1-25 and J1-26.
See Tables 6 and 7 for the data bits of the
MAX5856A, with respect to header J1 on the
MAX5858A EV kit.
PLL Clock Multiplier (MAX5858A and
MAX5856A only)
The MAX5858A (10 bit) and MAX5856A (8 bit) feature a
PLL clock multiplier that generates and distributes all
internally synchronized high-speed clock signals
required by the input data latches, interpolation filters,
and DAC cores. Jumper JU4 sets the PLL clock multiplier options. Table 8 lists the jumper selection.
Clock
The MAX5858A EV kit features two input clock options: a
single-ended input clock applied to CLKIN or a differential clock applied to CLKD. When evaluating the
MAX5858A or the MAX5856A, CLKIN is used in PLL
enabled mode, and CLKD is used in PLL disabled
mode. The clock signal applied to the CLKIN SMA input
connector has to meet CMOS logic-level requirements.
When evaluating the MAX5858, only the CLKD SMA input
connector is used. Jumpers JU1, JU4, JU10, and JU11
set the input clock mode for the MAX5858A. Table 9 lists
the jumper configurations.
