7) Connect a 1.8V power supply to the AVDD1 PC

board pad. Connect the ground terminal of this

supply to the AGND pad.

8) Connect a 3.3V power supply to the AVDD2 PC

board pad. Connect the ground terminal of this

supply to the AGND pad.

9) Connect a 1.8V power supply to the DVDD1 PC

board pad. Connect the ground terminal of this

supply to the DGND pad.

10) Connect a 3.3V power supply to the DVDD2 PC

board pad. Connect the ground terminal of this

supply to the DGND pad.

11) Connect a 3.3V power supply to the VDD_CK PC

board pad. Connect the ground terminal of this

supply to the GND_CK pad.

12) Turn on all five power supplies.

13) Enable the clock signal generator and the digital

pattern generator.

14) Set the clock signal generator output power

between +8dBm to +12dBm and the frequency

≤ 500MHz.

15) An LVDS logic-high signal at SELIQP/SELIQN

directs data into the I-DAC register. An LVDS logic-

low signal at SELIQP/SELIQN directs data into the

Q-DAC register. Refer to the LVDS-Compatible

Digital Inputs section in the MAX5876/MAX5877/

MAX5878 IC data sheets for detailed information on

the SELIQ function.

16) Use the spectrum analyzer to view the MAX5876/

MAX5877/MAX5878 output spectrums or view the

single-ended output waveforms by connecting an

oscilloscope to OUTPUTQ or OUTPUTI SMA con-

nectors.

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, current-

output 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.
