EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within an input voltage range of 0 V to 3.3 V.

Exceeding the specified input range may cause unexpected operation and/or irreversible

damage to the EVM. If there are questions concerning the input range, please contact a TI

field representative prior to connecting the input power.

Applying loads outside of the specified output range may result in unintended operation and/or

possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to

connecting any load to the EVM output. If there is uncertainty as to the load specification,

please contact a TI field representative.

During normal operation, some circuit components may have case temperatures greater than

40°C. The EVM is designed to operate properly with certain components above 40°C as long

as the input and output ranges are maintained. These components include but are not limited

to linear regulators, switching transistors, pass transistors, and current sense resistors. These

types of devices can be identified using the EVM schematic located in the EVM User’s Guide.

When placing measurement probes near these devices during operation, please be aware

that these devices may be very warm to the touch.

Purpose

1-2

1.1 Purpose

The DAC5674 EVM provides a platform for evaluating the DAC5674

digital-to-analog converter (DAC) under various signal, reference, and supply

conditions. This document should be used in combination with the EVM

schematic diagram supplied.

1.2 EVM Basic Functions

Digital inputs to the DAC can be provided with CMOS level signals up to

200 MSPS through a 40-pin header. This enables the user to provide

high-speed digital data to the DAC5674.

The analog output from the DAC is available via SMA connectors. Because

of its flexible design, the analog output of the DAC5674 can be configured to

drive a 50-Ωterminated cable using a 4:1 or 1:1 impedance ratio transformer,

or single-ended referred to GND.

The EVM allows for different clock configurations. The user can input a

differential ECL/PECL or TTL/CMOS level signal, to be used to generate a

single-ended or differential clock source. See the clock section for proper

configuration and operation.

Power connections to the EVM are via banana jack sockets. Separate sockets

are provided for the analog, digital, PLL, and I/O supply.

In addition to the internal bandgap reference provided by the DAC5674 device,

options on the EVM allow external reference to be provided to the DAC.

1.3 Power Requirements

The demonstration board has four power inputs. The first, +3.3VA, is required

to be +3.3 Vdc at banana jack J9 with the return going to J11. This is the analog

supply for the DAC5674. The second, +1.8 VD, is required to be +1.8 Vdc at

banana jack J14 with the return to J16. This is the digital +1.8-V supply for the

DAC5674. The third, +3.3VCLK, is required to be +3.3 Vdc at banana jack J10

with the return at J13. This is the digital supply for the internal PLL circuitry. The

fourth, +1.8/3.3VD_IO, is required to be either +1.8 or +3.3 Vdc at banana jack

J12 with the return at J15. This is the supply for the digital I/Os. The EVM can

be powered using only two supplies, but powering from four separate supplies

provides higher performance.

Note: Voltage Limits

Exceeding the maximum input voltages can damage EVM components.

Undervoltage may cause improper operation of some or all of the EVM

components.

DAC5674 EVM Operational Procedure

1-3

Overview

1.4 DAC5674 EVM Operational Procedure

The DAC5674 EVM can be set up in a variety of configurations to

accommodate a specific mode of operation. Before starting evaluation, the

user should decide on the configuration and make the appropriate

connections or changes. The demonstration board comes with the following

factory-set configuration:

-Differential clock mode using transformer T2 and a clock input at J4

-Transformer coupled output using transformer T1

-The converter is set to operate with internal reference. Jumper W2 is

installed between pins 1 and 2.

-Full-scale output current set to 20 mA through RBIAS resistor R1

-The DAC5674 output is enabled (sleep mode disabled). Jumper W3 is

installed between pins 1 and 2.

-Reset operation controlled through S1. Jumper W5 is installed between

pins 2 and 3.

-Internal PLL is disabled. Jumper W4 is installed between pins 1 and 2.
