The MAX5873/MAX5874/MAX5875 EV kits are designed
to simplify the evaluation of the MAX5873 (12-bit),
MAX5874 (14-bit), or MAX5875 (16-bit), 200Msps, dual
current-output DACs. The DACs operate with CMOS-
compatible digital data inputs, a single-ended clock input
signal, an internal 1.20V reference voltage, 3.3V and 1.8V
power supplies.
The 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 volt-
age source U2 (MAX6161) and a test point connector
that can be used to overdrive the DACs’ internal 1.20V
bandgap reference. The EV kit board layout separates
the circuit power into digital, analog, and clock planes
to improve dynamic performance.
The EV kits can operate from a single 1.8V power sup-
ply 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
board operation. However, five separate power supplies
are recommended for optimum dynamic performance.
